What is AndroidX and Why It is Important to Migrate to AndroidX

If you're unfamiliar with the phrase, AndroidX is a brand-new open-source initiative that Google is introducing to package libraries with Jetpack. In short, Google decided to start cleaning up their act and utilise a new approach along with new library names because the old method of managing libraries was becoming difficult.

AndroidX Overview

The Android team leverages the new open-source project called AndroidX to create, test, and distribute libraries for Jetpack.

A significant improvement over the original Android Support Library is AndroidX. Similar to the Support Library, AndroidX is developed separately from the Android OS and offers backward compatibility between different Android releases. By offering feature parity and additional libraries, AndroidX completely replaces the Support Library. Additionally, AndroidX has the following capabilities:

All AndroidX packages are located in a single namespace that begins with the letters android x. The comparable AndroidX.* packages have been mapped to the Support Library packages. See the Package Refactoring page for a complete mapping of all the old classes and build objects to the new ones.

Why migrate to AndroidX?

The support library is no longer being maintained and is now at version 28.0.0. Therefore, moving to AndroidX is crucial and necessary if we want bug fixes or new features that would previously have been included in the Support Library. The AndroidX namespace will be used for the release of all new Jetpack libraries.

There are a lot of benefits to switching from Android Support Library to AndroidX. The most recent version information is below:

Android 10 (API level 29)*

August 3, 2020: Required for new apps

November 2, 2020: Required for app updates

Better package management:

You get better consistent naming, more regular releases, and independent yet standardised versioning with AndroidX. Other libraries, such as Google Play services, Firebase, Butterknife, Databinding Mockito, and SQL Delight, have switched to using the AndroidX namespace libraries..

Migration is mandatory:

The AndroidX namespace will be used for the release of all new Jetpack libraries. You must switch to the AndroidX namespace in order to utilise features like Jetpack Compose or CameraX, for instance.

Hassle-free App Architecture:

If you want to create an app using Google's Single-Activity Architecture recommendation, you must use the Jetpack Navigation Component.

Google recommended arch:

MVVM pattern combined with Repos and Arch Components. To make the code base scalable, maintainable, and to get better CC, it is inevitable to create big scale programmes using a modular architecture to isolate via modules. Writing exams is made simple.

Conclusion:

There is no getting around this migration because the support library artefacts are being deprecated and all future development is moving to AndroidX. XcelTec is the best option if you want to transfer an existing Android app to Android X. We are a software company that has long offered the top mobile and web solutions.

Why You Choose Kotlin Over Java For The Android App Development?

If you meet with an experienced Android app developer, working for long years, then JAVA is perhaps his or her first preferable go-to language. Although JAVA 8 is already released, there are some rumors that remains waving that, it'll become obsolete within a couple of years.

The rumor is sort of true due to its endless try-catch blocks, lack of support for functional programming features, the notorious NullPointerException, and Verbose syntax and it's created to be a backward-compatible language. It means the newly launched version has got to support the previous version. And there also are some problems with adding new features thereto.

Whereas Kotlin is an open-source newly developed a politician programming language for Android since 2018. Supported the Java Virtual Machine (JVM) and JavaScript, it's statically typed language.

Before diving within the context, let's determine why Kotlin is introduced. It’s introduced to enhance syntax, also as concise expressions and abstractions.

>Kotlin is suggested by many app developers and Google, because

1. Using the Kotlin Multiplatform Framework you'll compile to almost every platform including Android, JVM, JavaScript, and native. Ready to you'll able to extract one common database which will target all of them at an equivalent time.

2. Switching JAVA to Kotlin may be a very easy process. Just install the recyclerview in kotlin, add it to the Gradle build files and click on for conversion.

3. New modules written by Kotlin can run smoothly alongside the prevailing Java code. It compatible with all Java libraries and frameworks, the JVM, and may integrate with the Gradle or Maven build systems.

4. The matter with Java is that it allows developers to assign a null to any variable. Once you attempt to use an object reference, features a null value then you'll face the NullPointer Exception. But in Kotlin, by default, there's not any nullable variable is present.

5. An extension function is missing in Java. Whereas Kotlin allows adding behavior and new functionality to a category without actually directly extending it or employing a design pattern. This is often an excellent feature that comes from C#.

6. The most feature of Kotlin is higher-order functions. It needs 20% less coding than Java and adopting Kotlin doesn't cost anything.

Kotlin provides many extraordinary safety mechanisms available while being more concise and revealing than Java at an equivalent time. That's why most Android app developers in Sydney are using it to develop an application.

There are some business benefits also. List in kotlin reduced the timelines allocated for projects because the language can solve more problems with fewer lines of code. And therefore the feature also supports maintenance needs. There’s little or no area for bugs to cover and therefore the excellent readability of the language makes locating bugs easier for developers, leading to fewer crashes.

Kotlin is proved a superior programming for mobile app development and presents app developers with a scope of opportunity with modern programming. Overall, Kotlin is setting a replacement standard. Since 2018, nearly 1.5 million developers wrote in Kotlin code which number has nearly doubled in August 2019. With immense support from JetBrains and Google, it's getting to prove that Kotlin is going to be the game-changer.

What is AndroidX and Why It is Important to Migrate to AndroidX

If you haven’t heard the term yet, AndroidX is the new open-source project being rolled out by Google to package libraries with Jetpack. Basically, the old way of managing libraries was becoming complicated and so Google decided to start cleaning up their act and use a new system, along with new library terms.

AndroidX Overview

AndroidX is the new open-source project that the Android team uses to develop, test, and package, version, and release libraries within Jetpack.

AndroidX is a major enhancement to the original Android Support Library. Like the Support Library, AndroidX crafts independently from the Android OS and delivers backward-compatibility across Android releases. AndroidX fully replaces the Support Library by providing feature equivalence and new libraries.

In addition, AndroidX includes the following features:

All packages in AndroidX live in a consistent namespace starting with the string android x. The Support Library packages have been mapped into the equivalent AndroidX.* packages. For a full mapping of all the old classes and build objects to the new ones, see the Package Refactoring page.

Unlike the Support Library, AndroidX packages are independently maintained and updated. The AndroidX packages use strict Semantic Versioning starting with version 1.0.0. You can update AndroidX libraries in your project independently.

All new Support Library development will occur in the AndroidX library. This includes maintenance of the original Support Library artefacts and the introduction of new Jetpack components.

Why migrate to AndroidX?

The final version of the support library is 28.0.0 and it’s no longer maintained. So, if we want bug fixes or new features that would have previously gone into the Support Library, It is important and mandatory to migrate to AndroidX. All new Jetpack libraries will be released in AndroidX namespace.

There are many reasons to migrate Android Support Library to AndroidX – The latest version details are below:

Android 10 (API level 29)*

August 3, 2020: Required for new apps

November 2, 2020: Required for app updates

Better package management:

With AndroidX, you get standardized and independent versioning, as well as better standardized naming and more frequent releases. Other libraries have migrated to use the AndroidX namespace libraries, including Google Play services, Firebase, Butter knife, Data binding Miskito, and SQL Delight among others.

Migration is mandatory:

All new Jetpack libraries will be released in AndroidX namespace. So, for example, to take advantage of Jetpack Compose or CameraX, you need to migrate to the AndroidX namespace.

Hassle-free App Architecture:

Jetpack Navigation Component is imperative to follow Google recommended Single-Activity Architecture app approach.

Google recommended arch:

MVVM pattern with Repos, as well as Arch Components. They’re inevitable to build large scale apps in the modular arch to isolate via modules to make the code base maintainable, scalable, and to get better CC. Writing tests made easy.

Conclusion:

The support library artefacts are being deprecated and all future development is going into AndroidX, so there’s no avoiding this migration. If you want to migrate your existing Android app to the Android X; XcelTec is the right choice for you. We are a tech firm providing the best solution on the web and mobile for many years.

Little about XcelTec:

XcelTec operates following the mission of “Delivering Excellence in Technology” by constantly converting customer’s requirements into creative & valuable solutions.

Getting Started with the React Native Navigation Library

One of the most important aspects of React Native app development is the navigation. It’s what allows users to get to the pages they’re looking for. That’s why it’s important to choose the best navigation library to suit your needs.

If your app has a lot of screens with relatively complex UI, it might be worth exploring React Native Navigation instead of React Navigation. This is because there will always be performance bottlenecks with React Navigation, since it works off the same JavaScript thread as the rest of the app. The more complex your UI, the more data has to be passed to that bridge, which can potentially slow it down.

In this tutorial, we’ll be looking at the React Native Navigation library by Wix, an alternative navigation library for those who are looking for a smoother navigation performance for their React Native apps.

Prerequisites

Knowledge of React and React Native is required to follow this tutorial. Prior experience with a navigation library such as React Navigation is optional.

App Overview

In order to demonstrate how to use the library, we’ll be creating a simple app that uses it. The app will have five screens in total:

Initialization: this serves as the initial screen for the app. If the user is logged in, it will automatically navigate to the home screen. If not, the user is navigated to the login screen.

Login: this allows the user to log in so they can view the home, gallery, and feed. To simplify things, the login will just be mocked; no actual authentication code will be involved. From this screen, the user can also go to the forgot-password screen.

ForgotPassword: a filler screen, which asks for the user’s email address. This will simply be used to demonstrate stack navigation.

Home: the initial screen that the user will see when they log in. From here, they can also navigate to either the gallery or feed screens via a bottom tab navigation.

Gallery: a filler screen which shows a photo gallery UI.

Feed: a filler screen which shows a news feed UI.

Here’s what the app will look like:

You can find the source code of the sample app on this GitHub repo.

Bootstrapping the App

Let’s start by generating a new React Native project:

react-native init RNNavigation --version [email protected]

Note: we’re using a slightly older version of React Native, because React Native Navigation doesn’t work well with later versions of React Native. React Native Navigation hasn’t really kept up with the changes in the core of React Native since version 0.58. The only version known to work flawlessly with React Native is the version we’re going to use. If you check the issues on their repo, you’ll see various issues on version 0.58 and 0.59. There might be workarounds on those two versions, but the safest bet is still version 0.57.

As for React Native version 0.60, the core team has made a lot of changes. One of them is the migration to AndroidX, which aims to make it clearer which packages are bundled with the Android operating system. This essentially means that if a native module uses any of the old packages that got migrated to the new androidx.* package hierarchy, it will break. There are tools such as jetifier, which allows for migration to AndroidX. But this doesn’t ensure React Native Navigation will work.

Next, install the dependencies of the app:

react-native-navigation — the navigation library that we’re going to use.

@react-native-community/async-storage — for saving data to the app’s local storage.

react-native-vector-icons — for showing icons for the bottom tab navigation.

yarn add react-native-navigation @react-native-community/async-storage react-native-vector-icons

In the next few sections, we’ll be setting up the packages we just installed.

Setting up React Native Navigation

First, we’ll set up the React Native Navigation library. The instructions that we’ll be covering here are also in the official documentation. Unfortunately, it’s not written in a very friendly way for beginners, so we’ll be covering it in more detail.

Note: the demo project includes an Android and iOS folders as well. You can use those as a reference if you encounter any issues with setting things up.

Since the name of the library is very long, I’ll simply refer to it as RNN from now on.

Android Setup

In this section, we’ll take a look at how you can set up RNN for Android. Before you proceed, it’s important to update all the SDK packages to the latest versions. You can do that via the Android SDK Manager.

settings.gradle

Add the following to your android/settings.gradle file:

include ':react-native-navigation' project(':react-native-navigation').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-navigation/lib/android/app/')

Gradle Wrapper Properties

In your android/gradle/wrapper/gradle-wrapper.properties, update Gradle’s distributionUrl to use version 4.4 if it’s not already using it:

distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip

build.gradle

Next, in your android/build.gradle file, add mavenLocal() and mavenCentral() under buildscript -> repositories:

buildscript { repositories { google() jcenter() // add these: mavenLocal() mavenCentral() } }

Next, update the classpath under the buildscript -> dependencies to point out to the Gradle version that we need:

buildscript { repositories { ... } dependencies { classpath 'com.android.tools.build:gradle:3.0.1' } }

Under allprojects -> repositories, add mavenCentral() and JitPack. This allows us to pull the data from React Native Navigation’s JitPack repository:

allprojects { allprojects { repositories { mavenLocal() google() jcenter() mavenCentral() // add this maven { url 'https://jitpack.io' } // add this } }

Next, add the global config for setting the build tools and SDK versions for Android:

allprojects { ... } ext { buildToolsVersion = "27.0.3" minSdkVersion = 19 compileSdkVersion = 26 targetSdkVersion = 26 supportLibVersion = "26.1.0" }

Lastly, we’d still want to keep the default react-native run-android command when compiling the app, so we have to set Gradle to ignore other flavors of React Native Navigation except the one we’re currently using (reactNative57_5). Ignoring them ensures that we only compile the specific version we’re depending on:

ext { ... } subprojects { subproject -> afterEvaluate { if ((subproject.plugins.hasPlugin('android') || subproject.plugins.hasPlugin('android-library'))) { android { variantFilter { variant -> def names = variant.flavors*.name if (names.contains("reactNative51") || names.contains("reactNative55") || names.contains("reactNative56") || names.contains("reactNative57")) { setIgnore(true) } } } } } }

Note: there are four other flavors of RNN that currently exist. These are the ones we’re ignoring above:

reactNative51

reactNative55

reactNative56

reactNative57

android/app/build.gradle

On your android/app/build.gradle file, under android -> compileOptions, make sure that the source and target compatibility version is 1.8:

android { defaultConfig { ... } compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 targetCompatibility JavaVersion.VERSION_1_8 } }

Then, in your dependencies, include react-native-navigation as a dependency:

dependencies { implementation fileTree(dir: "libs", include: ["*.jar"]) implementation "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}" implementation "com.facebook.react:react-native:+" implementation project(':react-native-navigation') // add this }

Lastly, under android -> defaultConfig, set the missingDimensionStrategy to reactNative57_5. This is the version of RNN that’s compatible with React Native 0.57.8:

defaultConfig { applicationId "com.rnnavigation" minSdkVersion rootProject.ext.minSdkVersion targetSdkVersion rootProject.ext.targetSdkVersion missingDimensionStrategy "RNN.reactNativeVersion", "reactNative57_5" // add this versionCode 1 versionName "1.0" ndk { abiFilters "armeabi-v7a", "x86" } }

The post Getting Started with the React Native Navigation Library appeared first on SitePoint.

What are the new features of React Native version 0.60?

React Native has been popular among the developer’s community since its launch. The Cross-Platform Mobile App Development Framework is being widely used. The reason behind the success is the highly dynamic applications that are developed using the framework. With React Native, one can create code for the application which is up to 92% reusable. Although, nothing is perfect and hence the framework has been updated into 0.60. Therefore, in order to tell you about all the latest features offered, we have written this article.

Accessibility: The new React Native build comes with greater accessibility. The announce For Accessibility API has been improved from the previous one. There are also changes in roles, action support, flags, and much more. There are various other improvements as well like support for “reduction motion”, better android keyboard accessibility options, CALayer for drawing text etc.

Migration: The android ecosystem for the React Native 0.60 has finally been migrated to AndroidX. This means that from onwards with this build the React Native apps will run on AndroidX.

Start Screen: The new React Native 0.60 comes with a brand new screen for launching the tool. This one has been made more user-friendly. It gets the user Document links, editing app.js, how to align the website, and debug menu.

Project Extractions: Well, the netinfo and the webview have been made into separate repositories. This has been done to make the Lean Core projects more easy to develop.

The new version has been completely migrated. Also, based on the feedback by the community, Geolocation has also been removed from there.

CocoaPods: This time the iOS has been made compatible to run in Xcode. Now the CocoaPod function which has been made default for Objective-C and Swift Cocoa Projects. From now onwards, the developers have also been advised to use xcworkspace file to run the React Native project.

Autolinked Native Modules: The ‘Autolink’ feature on the React Native CLI has been upgraded for ease. Now one can easily avoid using React Native Link making development easier than before. A linking procedure has been updated by the team for the ease of developers.

Upgrade Helper: The tool has been developed to convert an older written script of React Native into a newer one. With the Upgrade Helper, you can easily see the difference between the old and the new script. Although, in order to upgrade the script, one can also select the option of ‘Show me how to upgrade’.

So these were some of the newest features that one can witness in the latest version of React Native. We ourselves are an app development company known by the name Agicent Technologies. We have made various projects using React Native. In case, if you want then you can check out our app cost calculator. We hope this article may have been of some help to you. Also, thank you for reading it until the end.

Introduction to Android Jetpack

Most Android apps now use the support libraries to help users add all kinds of updated widgets and to address compatibility issues across Android devices and OS versions. You’d be hard-pressed to find an Android app that doesn’t use something from them, and they’re included as a dependency in template projects made in Android Studio. Widgets as fundamental as RecyclerView are included in them.

The support libraries are great to use, but they have evolved quite a bit over the years and the names have become somewhat confusing. There are com.android.support:support-v4 and com.android.support:support-v13, for example. Looking at the names alone, do you know what classes are in them? The names are supposed to designate what version of Android they support, but, as they have evolved, the minimum version has increased to API Level 14.

Google has realized that this variety of ever-changing libraries is very confusing for new (and old) developers and has decided to start over. Consequently, it has created Android Jetpack as a way of both providing guidance and also as a recommended set of libraries and tools. Through Jetpack, Google provides components that form a recommended way to architect your app. Furthermore, Google hopes that Jetpack will eliminate boilerplate code and simplify complex tasks while still providing backwards compatibility.

Note: If you’re new to Android Development or Kotlin, it’s highly recommended that you start with Beginning Android Development with Kotlin to learn your way around the basic tools and concepts.

To help address version confusion, Google is also resetting all of the Jetpack-related libraries to version 1.0.0 and starting their package names with a base name of androidx. Moreover, each component will be in its own library, though it’s important to note that Google is still working on transitioning libraries to the new package names.

There are also a couple of other resources in Jetpack, including the Android KTX library, which makes it easier to use Kotlin with Android. And, finally, Android Studio 3.2 Canary 14+ now has a Migrate to AndroidX option to convert your existing code and libraries to androidx (but I would recommend you wait until they are out of alpha, since pretty substantial known issues exist in the Canary 14 and 15 conversions).

Jetpack is broken up into four main areas: Architecture, Foundation, Behavior and UI. Most of the items in Jetpack are a re-arrangement and categorization of existing libraries, but a few of the items are new. By the end of this article, you should have a good sense of Jetpack’s features and where to find more information on each of them.

Jetpack: Architecture

The Architecture area of Jetpack includes eight different libraries and tools that help you architect your app and manage the data used by and displayed in the app. Most of these are existing libraries. However, there are three new libraries: Navigation, Paging, and WorkManager. Beginning with the newest libraries:

Navigation

Navigating between activities and/or fragments has never been easy. Now, with the Navigation library and the navigation viewer built into Android Studio, you can visually design how your screens are connected to one another. Many people have noticed that this is similar to Storyboards in Apple’s Interface Builder for iOS app development.

Using Navigation, you visually connect one screen to another using “destinations”. You create a navigation graph that will have a starting destination that can have actions to go to other destinations. The great thing about this is that you can define animations in the visual editor. The library even handles deep linking into your app. Passing data between destinations can be done in a safe way with a new plugin called safeargs. You can define what arguments the Fragments in the navigation graph accept from within the navigation file itself.

Here is a screenshot of two fragments with an action between the two. You can set up your app to navigate to the second fragment from inside a button click listener in the first fragment.

Note: As of this writing, the Navigation libraries do not work well with the androidx versions of the support libraries. They work sufficiently with the existing support libraries but not the new ones. Be sure to check the release notes on each version of Android Studio 3.2 to see when this has been addressed.

You can find more information about Navigation here: Navigation.

Paging

Have you ever had to deal with large amounts of related data? Maybe too much for you to download at once? The Paging library will help by providing ways to handle the paging of data in a RecyclerView.

The Paging library uses several key classes: PagedList, PagedListAdapter, and DataSource. PagedList is a list that loads data lazily from a DataSource, allowing the app to load data in chunks or pages. PagedListAdapter is a custom RecyclerView.Adapter that handles pages with a DiffUtil callback.

For the DataSource, you will use one of three different subclasses: PageKeyedDataSource, ItemKeyedDataSource, or PositionalDataSource.

You can find more information here: Paging.

WorkManager

Over the years, there have been several systems built into Android for handling background jobs or alarms. They differ on different versions of Android and you have to write a lot of code to handle the different versions of the OS.

WorkManager solves this problem and gives you one library for creating deferrable, asynchronous tasks and defining when they should run. You can define one-time jobs or repeating jobs.

You can find more information here: WorkManager.

Data Binding

This library has been around for awhile. Data Binding lets you bind your data to your layout in XML, so that, when you change your data in running code, the views defined by the layout are automatically updated. Moreover, when your UI changes, your data objects are updated.

You can find more information here: Data Binding.

Lifecycle

The Lifecycle library helps you listen for lifecycle events in other components besides an activities and fragments. This allows you to have lifecycle-aware logic in places other than just an Activity or Fragment. The library works by using annotations on methods so you get notified for the events that you are interested in.

You implement LifecycleObserver, annotate methods and add this observer to a lifecycle owner, which is usually an Activity or Fragment. The LifecycleObserver class can get the current lifecycle state by calling lifecycle.getCurrentState() and can use this information to avoid calling code when not in the correct state.

A LifecycleOwner is an object that has Android lifecycle events. The support library Activity and Fragment classes already implement the LifecycleOwner methods. A LifecycleOwner has a Lifecycle object that it can return to let the observer know what the current state is.

You can find more information here: Lifecycles.

LiveData

The LiveData library uses the Observer pattern for data but handles it in a lifecycle-aware manner. You get the benefits of automatic UI updates when data changes without calling UI elements when the UI is not in the correct state.

LiveData is the class that implements the observer pattern, holds that data, and notifies listeners when that data has changed.

You can find more information here: LiveData.

Room

If you have ever struggled working with the SQLite database in an Android app, you will appreciate what the Room library does for you. You create several simple classes that define your data and how to access them, and the Room library will do most of the rest. The only SQL code you have to write is for queries, which are usually pretty straightforward. And you gain compile-time checks of your SQL code when using Room.

There are three important classes you need to use with Room: Database (this contains your main entry point and holds a reference to the database object for the app), Entity (you create one for each table in the database), and DAO (this contains the methods for retrieving and managing the data).

You can find more information here: Room.

ViewModel

While the Room library persists your data in permanent storage, the ViewModel class allows you to hold onto data in device memory in a lifecycle-aware manner. One of the nice features of a ViewModel is that it can survive the re-construction of an Activity or Fragment over a configuration change such as a device rotation. The system will hold onto that ViewModel re-associate it with the Activity or Fragment. ViewModels are also where you can load data in the background and use LiveData to notify listeners that the data is ready.

You can find more information here: ViewModel.

Jetpack: Foundation

The Foundation area of Jetpack involves core system components, Kotlin extensions and Testing Libraries. This includes the AppCompat library, which you’ve probably been using for awhile, and the new Kotlin KTX extension library for easier development in Kotlin.

Testing is very important and has it’s own section to with frameworks to let you test your app, for both UI testing or unit testing.

Android app codebases are getting bigger and bigger, so you’ll want to visit the Multidex section of Foundation to see how to handle the 64K method limit.

You can find more information about what’s available in Foundation here: Foundation.

AppCompat

The AppCompat library in Jetpack Foundation consists of all of the components from the old v7 libraries. This includes:

AppCompat

Cardview

GridLayout

MediaRouter

Palette

RecyclerView

Renderscript

Preferences

Leanback

Vector Drawable

Design

Custom tabs

And even a few others…

You can find more information here: AppCompat.

Android KTX

Android KTX is the only new library in Foundation and is a set of Kotlin extensions designed to streamline the development of Android apps when using Kotlin.

There are several KTX modules that are linked to other libraries in Jetpack. For instance, if you are working with the Navigation library, then you could use:

android.arch.navigation:navigation-common-ktx

android.arch.navigation:navigation-fragment-ktx

android.arch.navigation:navigation-runtime-ktx

and android.arch.navigation:navigation-ui-ktx

SharedPreferences is an example of how using KTX can make your code simpler. Take a look at the Kotlin code below:

sharedPreferences.edit() .putBoolean("key", value) .apply()

Compare that with the KTX-based code:

sharedPreferences.edit { putBoolean("key", value) }

The KTX code is streamlined a bit and removed the need to add apply().

And here’s a SQLite example without KTX:

db.beginTransaction() try { // insert data db.setTransactionSuccessful() } finally { db.endTransaction() }

And the corresponding KTX version:

db.transaction { // insert data }

KTX streamlines a SQLite transaction into a simple function call with a trailing lambda.

You can find more information here: Android KTX.

Test

The Test part of Foundation includes the Espresso UI testing framework and AndroidJUnitRunner for unit testing. Unit tests are for writing small tests on the logic within your code, usually at the level of individual methods. They should run fast and help you test a specific piece of logic. Espresso is used for the testing of UI elements.

You can find more information here: Testing.

Multidex

As you build out your app and include more and more libraries, your app can grow large enough that you need to use the Multidexing capabilities of Android. Once your app includes more than 65,536 methods across all classes, you will need to have the system split your .dex file (basically, a .zip file of classes) into multiple .dex files.

You can learn more about multidexing and how to use it here: Multidex.

Jetpack: Behavior

The Behavior area of Jetpack features libraries that help you interact with your user through the UI, including using video or sound. It includes many components such as media, notifications, permissions, downloading, sharing and the new Slices library.

You can find more information here: Behavior.

Notifications

Android Notifications have been around since the beginning but have changed over time. They have become more expressive and can contain buttons and images. Since Android 5.0 Lollipop, a notification called a heads-up notification can be displayed. You can even use notifications on Android Wear and TV for controlling media.

You can find more information here: Notifications.

Permissions

This part of the Behavior area showcases how to use and request permissions. Since Android 6.0 Marshmallow, permissions are now required to be requested and given before certain elements of a device’s components can be accessed, such as contacts, location and camera information. You declare permissions in the manifest, and you must deal with both cases of a user accepting or denying your permission request.

You can find more information here: Permissions.

Sharing

The Sharing part of Behavior explains how to share content and the ShareActionProvider class and how to use it. You will can share information with other apps and receive information from other apps. You can create a share action, share files and use ContentProviders for sharing data.

You can find more information here: Sharing.

Media

The Behavior area of Jetpack includes the MediaPlayer and AudioManager classes. You can play media and sounds, use the MediaPlayer in a service, and control the device volume. Android supports various media formats. You can also use the ExoPlayer library, which Google uses for it’s own media players in apps such as YouTube.

You can find more information here: Media.

Download Manager

The DownloadManager service helps you download files in the background. Avoid dealing with connection problems, retrying and even system reboots by using the DownloadManager service. Since the DownloadManager is a system service, you can just start a download and listen for a broadcast event to handle the finished download. No need to worry about network issues or crashes.

You can find more information here: Download Manager.

Slices

The Slices library is new and lets you create UI templates to share your data through the system in rich, flexible layouts. One of the examples Google gave at Google I/O was a weather app that can show more data depending on the space it has to show. Currently, it is only used by the Google Search App but should extend to the Google Assistant.

You can make your app data available to these apps using Slices so that a user can find information from your app by using Google Search or the Assistant.

You can find more information here: Slices

Jetpack: UI

Most of the UI libraries in Jetpack are based on existing code. They include: animations, fragments, palettes, layouts, Emojis, Android Auto, Wear and TV. The EmojiCompat library is the newest of the libraries and gives you up-to-date emojis and the fonts needed to use them.

You can find more information about the UI area here: UI.

Animation

This part of Jetpack includes APIs for the different types of animations available on Android. The Jetpack site documentation covers the old as well as new ways to use animations. Vector graphics and vector animations are included as well.

There is also a physics-based animation system that includes spring and fling animations. You can setup transitions between activities as well as property and object animations. You can also set a layout to animate any updates you make to the layout.

You can find more information here: Animations.

Emoji

EmojiCompat handles emoji characters and uses downloadable font support. This allows your app to stay up to date with the latest emojis without depending on the Android OS. Whenever you update this library dependency, you will have the latest emojis. There is a concrete Span class called EmojiSpan that is used to create emojis in your text.

You can find more information here: Emoji.

Fragment

The Fragment support class has moved into this part of Jetpack. It includes the different kinds of fragments, such as: DialogFragment, ListFragment, and PreferenceFragmentCompat. An important part of a Fragment is the lifecycle, and the Fragment class included in Jetpack is well-integrated with the Lifecycle class in Jetpack: Architecture.

You can find more information here: Fragments.

Layout

A Layout defines the Views and ViewGroups in your app. In the Jetpack Layout documentation, you learn how to declare layouts in XML and in code. It also describes some of the more common layouts, such as LinearLayout, RelativeLayout and the newer ConstraintLayout. Moreover, you’ll pick up tips on more specific features like creating lists of items with RecyclerView, as well as the card layout CardView.

You can find more information here: Layouts.

Palette

The Palette library allows you to pick colors for themes and from images to make your UI’s match your images. You can also create a palette and choose different colors using the Palette.Builder class. Some of the types of colors produced are: Light Vibrant, Vibrant, Dark Vibrant, Light Muted, Muted and Dark Muted.

You can find more information here: Palettes.

If you are building your app for Android TV, then the TV part of Jetpack is for you. You can control TV Hardware and controllers and create a navigation system that works for TVs. There is the leanback theme that is used for TV layouts and the Leanback library helps with TV controls. You can setup a D-pad controller to let users navigate the TV UI.

You can find more information here: TV.

Wear

Wear OS is the version of Android for wearable devices. You can create an app that plays media, controls your media from a watch, or create a standalone watch app or watch face.

You can find more information here: Wear.

Auto

Jetpack helps you develop apps for Android Auto — audible only, messaging, working with hardware and more. You can provide audio playback for the car as well as messaging. You can test Auto apps on the car screen using the Desktop Head Unit (DHU), which is a testing tool that allows you to test without the hardware.

You can find more information here: Auto.

Where to Go From Here?

As you can see, there is quite a lot included in Google’s new Android Jetpack package. All of the libraries you know and love can be found there, as well as several new ones.

In this article, you were introduced to the four main parts of Jetpack: Architecture, Foundation, UI and Behavior. Some of the new libraries, like the Navigation library, will change the way you write your apps, making it easier than ever. WorkManager solves a long standing problem of reliably running jobs at different times on different OS versions. Paging will help with larger data sets and let you use RecyclerViews and adapters with less code. The Android KTX library makes working in Kotlin even easier and will continue to evolve. Slices are new and, as you learn more, you should be able to make available more of your data outside of your app. With the Emoji library, you can have all of the latest and best emojis available.

Hopefully this post provided a good overview of what is available in Jetpack and will get you excited about using something new. The main Jetpack page is located here: Android Jetpack

If you would like more in-depth information on Jetpack Navigation, you can find a screencast here. We also have screencasts on LiveData, ViewModel, and Paging Library. Finally, you can find a short introduction to WorkManager in our Background Processing course here.

Let us know what part of Android Jetpack you are most looking forward to using in the discussion forum below!

What are Google Play’s new mobile app requirements?

Google Play set out many criteria in their app guidelines that you need to follow. These changes may cause some issues as you try to stay up to date. In this post, we’ll tell you what changes you need to make in order to guarantee that your app is fully compatible with Google’s new requirements.

Google made changes to the behavior of the API to increase security and privacy. The bindService() implicit intents in Android 5.0 aren’t supported currently. There are also new changes in the Runtime permissions. Since every Android app runs in a reduced-access sandbox, so the app has to ask for permission when it wants to use materials or information outside that sandbox. Google Play asks that you state the need in the app manifest and then you have to approve each permission right before the actual runtime.

This permission change is for Android 6.0 and higher. You can still use the Android Support Library to make older versions of Android compatible. Google Play also updated the Android Support Library with the release of Android 9.0 (API level 28); the new version is called AndroidX and is part of Jetpack. The existing support library still exists with the AndroidX library, but it also includes Jetpack’s most recent components.

Google Maven holds onto all versions prior to API 27 and Google Play says that they’ll be packaged as “android.support.” But, all new development will take place on the AndroidX library, so Google Play recommends that you develop new projects here. If you have an existing project, they recommend that you migrate it over.

To further increase secure connections, Google Play has changed the user added CAs to not be trusted by default in the case of Android 7.0. They also require explicit user approval from apps to access the user account in Android 8.0.

For MetaData, Google now has a small MetaData on top of each APK so that each app release is officially verified by Google Play. They don’t allow apps with any deceptive, incorrect, or explicit metadata that isn’t pertinent to what the app is about. This entails every area of the app — the title, description, all images, and icons. They also don’t allow user testimonials in the app’s description any longer. Authentication is important for users to know that an app is legitimate, so they’re spending time to ensure that each app functions as advertised.

Here Are Google Play’s New Requirements for Texts & Images

Google Play store now allows 2–8 screenshots for each supported device, i.e., smartphones, tablets, Android T.V, Android Wear, etc. But, to publish your store listing, you have to upload at least two screenshots for each device type. It needs to either be a JPEG or 24-bit PNG (no alpha) with minimum dimensions of 320px and maximum dimensions of 3840px.

Screenshots aren’t the only images that need to be formatted. Google Play requires one splash screen for an iPhone display and one for an iPad display, both retina and non-retina displays. Whether you’re using a photo or video, dimensions should be 1024px by 500px. If you choose a video, make sure to use an individual video’s YouTube URL, not a YouTube playlist or channel URL. The video shouldn’t be longer than two minutes.

Google Play now requires icon images to fit into the new, standardized icon shape — the square with rounded corners known as a “squircle.” It needs to be hi-res, material icons used through Android M, and adaptive icons for Android O.

Last week, the second edition of the .NET Conf: Focus series took place, focusing on Xamarin. Xamarin extends the .NET platform with tools and libraries specifically for building mobile apps. The focus conferences are free, one-day livestream events featuring speakers from the community and .NET product teams. The first event of the series was earlier this year, in January, focused on Blazor. The focus series is a branch off of the original .NET Conf, an annual event organized by the .NET community and Microsoft that showcases the latest developments for the .NET platform. The 2019 edition of .NET Conf was a three-day event where Microsoft officially released .NET Core, ASP.NET, and EF Core 3.0, together with C# 8.0 and F# 4.7. In opposition, each focus event targets a specific .NET-related technology, providing a series of in-depth, hands-on sessions aimed at .NET developers. .NET Conf: Xamarin was the largest Xamarin digital event of the year. The conference started with an overview of the latest developments related to Xamarin and mobile development. In this context, Amanda Silver, CVP of product for developer tools at Microsoft, talked about Xamarin and its relationship with Visual Studio. Performance, productivity, and support to modern mobile development were particularly emphasized: Xamarin's install size was reduced from 23GB (Visual Studio 2017) to 6 GB (Visual Studio 2019), providing faster install and startup times. XAML Hot Reload, Hot Restart (features for faster debugging and testing), and IntelliCode (smart coding assistance) were also highlighted. The keynote also included a Xamarin development overview presented by David Ortinau and Maddy Leger, program managers for mobile development tools at Microsoft. The presentation featured an overview of the architecture of Xamarin apps and other topics presented in more detail during the conference, mostly related to Xamarin Forms functionalities and APIs. An interesting topic not covered in the following sessions, however, was the preview release of AndroidX Migrator, a tool to migrate Android projects to Xamarin. The remainder of the sessions were short (approx. 30 minutes), mostly following the keynote emphasis on performance and productivity. Other topics included: using Azure services to create a mobile backend for apps, creating dual-screen experiences, testing mobile applications, and using Reactive Extensions. One session, in particular, was targeted at ASP.NET developers, showing how they could start developing mobile applications with side-by-side feature implementation comparisons. A relevant takeaway from the conference is how the recent developments on Xamarin are aligned with Microsoft's efforts on establishing Visual Studio as a unified development platform. In the same manner, .NET 5 is announced as a unifying platform for desktop, Web, cloud, mobile, gaming, IoT, and AI applications. The next focus events start in June (expected), after Microsoft Build. Recordings of all .NET Conf and .NET Conf: Focus events are available in curated playlists on MSDN Channel 9.

Android Jetpack Navigation Stable Release

New Post has been published on https://languageguideto.com/awesome/android-jetpack-navigation-stable-release/

Android Jetpack Navigation Stable Release

Posted by Ian Lake, Software Engineering Lead& Jisha Abubaker, Product Manager

Cohesive tooling and guidance for implementing predictable in-app navigation

Today we’re happy to announce the stable release of the Android Jetpack Navigation component.

The Jetpack Navigation component’s suite of libraries, tooling and guidance offer a robust, complete navigation framework, freeing you from the challenges of implementing navigation yourself and giving you certainty that all edge lawsuits are managed correctly.

With the Jetpack Navigation component you can:

Handle basic user actions like Up& Back buttons so that they work consistently across devices and screens.

Allow users to land on any part of your app via deep connections and build consistent and predictable navigation within your app.

Improve type safety of debates passed from one screen to another, decreasing the the possibilities of runtime accidents as users navigate in your app.

Add navigation experiences like navigation drawers and bottom navigation consistent with the Material Design guidelines.

Visualize and manipulate your navigation flows easily with the Navigation Editor in Android Studio 3.3

The Jetpack Navigation component adheres to the Principles of Navigation, providing consistent and predictable navigation no matter how simple or complex your app may be.

iframe>

Simplify navigation code with Jetpack Navigation Libraries

The Jetpack Navigation component provides a framework for in-app navigation that attains it is feasible to abstract away the implementation details, keeping your app code free of navigation boilerplate.

To get started with the Jetpack Navigation component in your project, add the Navigation artifacts available on Google’s Maven storehouse in Java or Kotlin to your app’s build.gradle file:

dependencies

def nav_version= 2.0.0

// Java

implementation “androidx.navigation: navigation-fragment :$ nav_version”

implementation “androidx.navigation: navigation-ui :$ nav_version”

// Kotlin KTX

implementation “androidx.navigation: navigation-fragment-ktx :$ nav_version”

implementation “androidx.navigation: navigation-ui-ktx :$ nav_version”

Note: If you have not yet migrated to androidx .*, the Jetpack Navigation stable component libraries are also available as android.arch .* artifacts in version 1.0.0.

navigation-runtime: This core library powers the navigation graph, which provides the structure of your in-app navigation: the screens or destinations that make up your app and the actions that connect them. You can control how you navigate to destinations with a simple navigate() call. These destinations may be fragments, activities or custom destinations.

navigation-fragment: This library builds upon navigation-runtime and offer out-of-the-box support for fragments as destinations. With this library, fragment transactions are now managed for you automatically.

navigation-ui: This library allows you to easily add navigation drawers, menus and bottom navigation to your app consistent with the Material Design guidelines.

Each of these libraries offer an Android KTX artifact with the -ktx suffix that builds upon the Java API, taking advantage of Kotlin-specific language features.

Tools to help you build predictable navigation workflows

Available in Android Studio 3.3 and above, the Navigation Editor lets you visually create your navigation graph, allowing you to manage user journeys within your app.

With integration into the manifest merger tool, Android Studio can automatically generate the intent filters necessary to allow deep connecting to a specific screen in your app. With this feature, you can associate URLs with any screen of your app by simply setting an attribute on the navigation destination.

Navigation often involves passing data from one screen to another. For instance, your listing screen may pass an item ID to a details screen. Many of the runtime exceptions during navigation have been attributed to a lack of form safety guarantees as you pass debates. These exceptions are hard to replicate and debug. Learn how you can provide compile day type security with the Safe Args Gradle Plugin.

Guidance to get it right on the first try

Check out our brand new situated of developer guidebooks that encompass best practices to help you implement navigation correctly:

Create a deep-link for a destination

Conditional navigation

Animate transitions between destinations

Design for different form factors

Test navigation

What developers say

Here’s what Emery Coxe, Android Lead@ HomeAway, has to say about the Jetpack Navigation component:

“The Navigation library is well-designed and fully configurable, allowing us to integrate the library according to our specific needs.

With the Navigation Library, we refactored our legacy navigation drawer to subsistence a dynamic, runtime-based configuration using custom views. It allowed us to add/ remove new screens to the top-level experience of our app without creating any interdependencies between discreetly packaged modules.

We were also able to get rid of all anti-patterns in our app around top-level navigation, removing explicit casts and hardcoded hypothesis to instead rely directly on Navigation. This library is a fundamental component of modern Android development, and we intend to adopt it more broadly across our app moving forward.

Get started

Check out the migration guidebook and the developer guidebook to learn how you can get started employing the Jetpack Navigation component in your app. We also offer a hands-on codelab and a sample app.

Also check out Google’s Digital Wellbeing to find another real-world instance of in-app navigation using the Android Jetpack Navigation component.
