Build Android App On Mac

To build app bundles and support Dynamic Delivery, you can follow these steps: Download Visual Studio 16.4 or higher on Windows or Visual Studio for Mac 8.4 or higher on Mac. Prepare your application for Release; Build an Android App Bundle using Visual Studio. If you're not using an IDE, you can instead build an app bundle from the command line. Review the default Gradle build file file, build.gradle, located in app dir/android/app and verify the values are correct, especially the following values in the defaultConfig block: applicationId Specify the final, unique (Application Id) appid. Just to review, we installed the Android SDK, the platform dependencies, we installed VirtualBox and Genymotion. Then from there we did Ionic run Android, which then put our application on the Genymotion device. This is how you build Android applications for Ionic. AppMachine is an easy-to-use platform to build and design professional native apps for both iOS and Android. Using the drag-and-drop interface, you can combine different building blocks that offer. You can use Visual Studio for Mac to create almost any type of the application. It can be iOS, tvOS, Android, Mac,.NET Core, or even ASP.NET. As all the cool kids are now writing mobile apps, lets see what it takes in Visual Studio for Mac to create a C# application that will run on Android and iOS.

Run Android Apps On Pc

During a typical development cycle,you test an app using flutter run at the command line,or by using the Run and Debugoptions in your IDE. By default,Flutter builds a debug version of your app.

When you're ready to prepare a release version of your app,for example to publish to the Google Play Store,this page can help. Before publishing,you might want to put some finishing touches on your app.This page covers the following topics:

Adding a launcher icon

When a new Flutter app is created, it has a default launcher icon.To customize this icon, you might want to check out theflutter_launcher_icons package.

Alternatively, you can do it manually using the following steps:

1. Review the Material Design producticons guidelines for icon design.

2. In the /android/app/src/main/res/ directory,place your icon files in folders named usingconfiguration qualifiers.The default mipmap- folders demonstrate the correctnaming convention.

3. In AndroidManifest.xml, update theapplication tag's android:iconattribute to reference icons from the previousstep (for example,).

4. To verify that the icon has been replaced,run your app and inspect the app icon in the Launcher.

Signing the app

To publish on the Play Store, you need to give your app a digitalsignature. Use the following instructions to sign your app.

Create a keystore

If you have an existing keystore, skip to the next step.If not, create one by running the following at the command line:

On Mac/Linux, use the following command:

On Windows, use the following command:

This command stores the key.jks file in your homedirectory. If you want to store it elsewhere, changethe argument you pass to the -keystore parameter.However, keep the keystore file private;don't check it into public source control!

Note:

• The keytool command might not be in your path—it'spart of Java, which is installed as part ofAndroid Studio. For the concrete path,run flutter doctor -v and locate the path printed after‘Java binary at:'. Then use that fully qualified pathreplacing java (at the end) with keytool.If your path includes space-separated names,such as Program Files, use platform-appropriatenotation for the names. For example, on Mac/Linuxuse Program Files, and on Windows use'Program Files'.

• The -storetype JKS tag is only required for Java 9or newer. As of the Java 9 release,the keystore type defaults to PKS12.

Reference the keystore from the app

Create a file named /android/key.propertiesthat contains a reference to your keystore:

Warning: Keep the key.properties file private; don't check it into public source control.

Configure signing in gradle

Configure signing for your app by editing the/android/app/build.gradle file.

1. Add code before android block:

   With the keystore information from your properties file:

   Load the key.properties file into the keystoreProperties object.

2. Add code before buildTypes block:

   With the signing configuration info:

   Configure the signingConfigs block in your module's build.gradle file.

Release builds of your app will now be signed automatically.

Note: You may need to run flutter clean after changing the gradle file. This prevents cached builds from affecting the signing process.

For more information on signing your app, seeSign your app on developer.android.com.

Shrinking your code with R8

R8 is the new code shrinker from Google, and it's enabled by defaultwhen you build a release APK or AAB. To disable R8, pass the --no-shrinkflag to flutter build apk or flutter build appbundle.

Note: Obfuscation and minification can considerably extend compile time of the Android application.

Reviewing the app manifest

Review the default App Manifest file,AndroidManifest.xml,located in /android/app/src/main and verify that the valuesare correct, especially the following:

application

Edit the android:label in theapplication tag to reflectthe final name of the app.

uses-permission

Add the android.permission.INTERNETpermission if your application code needs Internetaccess. The standard template does not include this tag but allowsInternet access during development to enable communication betweenFlutter tools and a running app.

Reviewing the build configuration

Review the default Gradle build file file,build.gradle, located in /android/app andverify the values are correct, especially the followingvalues in the defaultConfig block:

applicationId

Specify the final, unique (Application Id)appid

versionCode & versionName

Specify the internal app version number,and the version number display string. You can do this by settingthe version property in the pubspec.yaml file. Consult the versioninformation guidance in the versions documentation.

minSdkVersion, compilesdkVersion, & targetSdkVersion

Specify the minimum API level,the API level on which the app was compiled,and the maximum API level on which the app is designed to run.Consult the API level section in the versions documentationfor details.buildToolsVersion

Specify the version of Android SDK Build Tools that your app uses. Alternatively, you can use the [Android Gradle Plugin] in Android Studio,which will automatically import the minimum required Build Tools for your appwithout the need for this property.

Building the app for release

You have two possible release formats when publishing tothe Play Store.

• App bundle (preferred)
• APK

Note: The Google Play Store prefers the app bundle format. For more information, see Android App Bundle and About Android App Bundles.

Mac pure heroine lipstick. Warning: Recently, the Flutter team has received several reports from developers indicating they are experiencing app crashes on certain devices on Android 6.0. If you are targeting Android 6.0, use the following steps:

• If you build an App BundleEdit android/gradle.properties and add the flag:android.bundle.enableUncompressedNativeLibs=false.

• If you build an APKMake sure android/app/src/AndroidManifest.xmldoesn't set android:extractNativeLibs=falsein the tag.

For more information, see the public issue.

Build an app bundle

This section describes how to build a release app bundle.If you completed the signing steps,the app bundle will be signed.At this point, you might consider obfuscating your Dart codeto make it more difficult to reverse engineer. Obfuscatingyour code involves adding a couple flags to your build command,and maintaining additional files to de-obfuscate stack traces.

From the command line:

1. Enter cd
   (Replace with your application's directory.)
2. Run flutter build appbundle
   (Running flutter build defaults to a release build.)

The release bundle for your app is created at/build/app/outputs/bundle/release/app.aab.

By default, the app bundle contains your Dart code and the Flutterruntime compiled for armeabi-v7a (ARM 32-bit), arm64-v8a(ARM 64-bit), and x86-64 (x86 64-bit).

Test the app bundle

An app bundle can be tested in multiple ways—this sectiondescribes two.

Offline using the bundle tool

1. If you haven't done so already, download bundletool from theGitHub repository.
2. Generate a set of APKs from your app bundle.
3. Deploy the APKs to connected devices.

Online using Google Play

1. Upload your bundle to Google Play to test it.You can use the internal test track,or the alpha or beta channels to test the bundle beforereleasing it in production.
2. Follow these steps to upload your bundleto the Play Store.

Build an APK

Although app bundles are preferred over APKs, there are storesthat don't yet support app bundles. In this case, build a releaseAPK for each target ABI (Application Binary Interface).

If you completed the signing steps,the APK will be signed.At this point, you might consider obfuscating your Dart codeto make it more difficult to reverse engineer. Obfuscatingyour code involves adding a couple flags to your build command.

From the command line:

1. Enter cd
   (Replace with your application's directory.)
2. Run flutter build apk --split-per-abi
   (The flutter build command defaults to --release.)

This command results in three APK files:

• /build/app/outputs/apk/release/app-armeabi-v7a-release.apk
• /build/app/outputs/apk/release/app-arm64-v8a-release.apk
• /build/app/outputs/apk/release/app-x86_64-release.apk

Removing the --split-per-abi flag results in a fat APK that containsyour code compiled for all the target ABIs. Such APKs are larger insize than their split counterparts, causing the user to downloadnative binaries that are not applicable to their device's architecture.

Install an APK on a device

Follow these steps to install the APK on a connected Android device.

From the command line:

1. Connect your Android device to your computer with a USB cable.
2. Enter cd where is your application directory.
3. Run flutter install.

Publishing to the Google Play Store

For detailed instructions on publishing your app to the Google Play Store,see the Google Play launch documentation.

Updating the app's version number

The default version number of the app is 1.0.0.To update it, navigate to the pubspec.yaml fileand update the following line:

version: 1.0.0+1

The version number is three numbers separated by dots,such as 1.0.0 in the example above, followed by an optionalbuild number such as 1 in the example above, separated by a +.

Both the version and the build number may be overridden in Flutter'sbuild by specifying --build-name and --build-number, respectively.

In Android, build-name is used as versionName whilebuild-number used as versionCode. For more information,see Version your app in the Android documentation.

After updating the version number in the pubspec file,run flutter pub get from the top of the project, oruse the Pub get button in your IDE. This updatesthe versionName and versionCode in the local.properties file,which are later updated in the build.gradle file when yourebuild the Flutter app.

Android release FAQ

Here are some commonly asked questions about deployment forAndroid apps.

When should I build app bundles versus APKs?

The Google Play Store recommends that you deploy app bundlesover APKs because they allow a more efficient delivery of theapplication to your users. However, if you're distributingyour application by means other than the Play Store,an APK may be your only option.

What is a fat APK?

A fat APK is a single APK that contains binaries for multipleABIs embedded within it. This has the benefit that the single APKruns on multiple architectures and thus has wider compatibility,but it has the drawback that its file size is much larger,causing users to download and store more bytes when installingyour application. When building APKs instead of app bundles,it is strongly recommended to build split APKs,as described in build an APK using the--split-per-abi flag.

What are the supported target architectures?

When building your application in release mode,Flutter apps can be compiled for armeabi-v7a (ARM 32-bit),arm64-v8a (ARM 64-bit), and x86-64 (x86 64-bit).Flutter does not currently support building for x86 Android(See Issue 9253).

How do I sign the app bundle created by flutter build appbundle?

See Signing the app.

How do I build a release from within Android Studio?

In Android Studio, open the existing android/folder under your app's folder. Then,select build.gradle (Module: app) in the project panel:

Next, select the build variant. Click Build > Select Build Variantin the main menu. Select any of the variants in the Build Variantspanel (debug is the default):

The resulting app bundle or APK files are located inbuild/app/outputs within your app's folder.

Play Store, Google's official Android app distribution platform for mobile apps running on Android OS, is usually the go-to place for Android Apps, but it's not the only place. Here's the list of some of the cool alternatives to Play Store where you can release and market your android app.

Google Play: Google Play, formerly Android Market, comes first in the list where you can release and market your Android app. Google Play is an official Android app distribution platform hosting nearly 3 million apps under various categories. Google Play should be your first choice when it comes to testing your app idea in the market.

Amazon Appstore: Amazon Appstore is the second biggest Android app distribution platform after Google Play. This is the biggest rival to Google play and offers free app release under various categories. Go, get your app listed on the Amazon AppStore to further boost your app downloads.

APKPure: APKPure is one of the fastest-growing mobile apps distribution platforms. This platform allows you to list both Android and iOS apps. The website receives nearly 500,000 daily visitors that shows you the huge potential to grow your app audience. ‍

Aptoide: Another popular app marketplace to launch your app. The app distribution platform claims to have more than 1 million apps available to be downloaded which generated 7 billion app downloads so far. Numbers clearly show the popularity of the app store and the potential for your app.
