If you're not using the IDE, you can build an app bundle from the command line. Then, upload your app bundle to the Play Console to test or publish your app. Download Android Studio 3. Keep in mind, using this option results in longer build times when compared to building and deploying only an APK. Enroll into app Play App Signing. Otherwise, you can't upload your app bundle to the Play Console.

Because the IDE and Google Play use the same tools to extract and install APKs on a device, this local testing strategy helps you to verify the following:. The tools that Android Studio and Google Play use to build your app bundle and convert it into APKs are available to you from the command line. That is, you can invoke these tools from the command line to locally build and deploy your app from an Android App Bundle.

If you want to build your app bundle from the command line, you can do so using either bundletool or the Android Gradle plugin. Android Gradle plugin: Authored by Google, this plugin comes bundled with Android Studio and is also available as a Maven repository. The plugin defines commands that you can execute from the command line to build an app bundle. Keep in mind, using bundletool to build your app bundle is a lot more complicated than simply running a Gradle task using the plugin.

However, this tool is useful for developers who want to generate app bundle artifacts in their CI workflow. To get started building your app bundle with either approach, read Build your app from the command line. Although the Android Gradle plugin is the easiest way to build your app bundle from the command line, you should use bundletool to deploy your app from an app bundle to a connected device.

The following are the different types of scenarios you can test for using bundletool :. Whether you want to share your app with your internal stakeholders, your internal QA team, a closed group of alpha testers, or a wider audience of beta testers, the Play Console provides you with several testing strategies. While the Play Console test tracks provide a method of progressing your app through formal testing stages, sometimes you want to quickly share your app with trusted testers over less formal channels, such as email or a text message.

By uploading your app bundle to the Play Console quick sharing page, you can generate a URL that you can easily share with others. Sharing your app this way provides these benefits:. When users click on the URL from their Android device, the device automatically opens the Google Play Store to download the test version of your app. To get started, and learn more about the capabilities and restrictions of this testing strategy, see Share your app with a URL or watch the video below.

This can be useful if, for example, you want to quickly test an earlier version of your app to check for performance regressions. Visit the Play Console app bundle explorer page and navigate to the download tab of any version you want to download to copy the install link. Alternatively, if you know the package name and version code for the version of your app you want to test, simply visit the following link from your test device:. When you upload your app and create a release in the Play Console, you can progress your release through multiple testing stages before pushing to production:.

Progressing your app through each of these testing stages allows you to open your app to wider audiences of testers before releasing your app to production. For more information on Play Console test tracks, go to Set up an open, closed, or internal test. When you upload an APK or app bundle to the open or closed track, you can identify issues for a wide range of devices running different versions of Android.

The pre-launch report on your Play Console helps you identify potential issues with the following:. After you upload your app bundle, test devices automatically launch and crawl your app for several minutes. The crawl performs basic actions every few seconds on your app, such as typing, tapping, and swiping.

After tests are complete, your results will be available in the pre-launch report section of your Play Console. To learn more, see the Play Console help topic about how to Use pre-launch reports to identify issues. To learn more, read the Play Console help topic about Reviewing your app bundle details.

Firebase App Distribution makes it easy to distribute pre-release versions of your app to trusted testers so you can get valuable feedback before launch. App Distribution lets you manage all of your pre-release builds in a central hub, and it gives you the flexibility to distribute these builds right from the console or using the command-line tools that are already part of your workflow.

There are a few steps you need to take to enable your project for Firebase App Distribution. Check out the Before you begin section of the Firebase documentation. After you've set up your project, choose how you want to integrate App Distribution with your workflow:.

Chrome OS devices. By default, Android Studio builds the debug version of your app, which is intended for use only during development, when you click Run. The Active Build Variant value for the module determines which build variant the IDE deploys to your connected device and is visible in the editor.

Figure 1. To switch between variants, click the Active Build Variant cell for a module and choose the desired variant from the list field. The Active Build Variant value for the module determines the build variant that the IDE deploys to your device and is visible in the editor. Figure 2. After you change the selection, the IDE syncs your project automatically. Changing either column for an app or library module will apply the change to all dependent rows. By default, new projects are set up with two build variants: a debug and release variant.

You need to build the release variant to prepare your app for public release. To build other variations of your app, each with different features or device requirements, you can define additional build variants. This error does not indicate a build issue with Gradle — it is only indicating that the Android Studio IDE itself cannot resolve symbols between the variants of the selected modules.

When v2 is selected, that class is not known by the IDE and it will fail to resolve it and show errors in the code of M1. These error messages appear because the IDE cannot load code for multiple variants simultaneously. The Run button builds and deploys your app to a device. However, to build your app to share or upload to Google Play, you'll need to use one of the options in the Build menu to compile parts or all of your project.

Before you select any of the build options listed in table 1, make sure you first select the build variant you want to use. Builds an APK of all modules in the current project for their selected variant. When the build completes, a confirmation notification appears, providing a link to the APK file and a link to analyze it in the APK Analyzer. If the build variant you've selected is a debug build type, then the APK is signed with a debug key and it's ready to install.

When the build completes, a confirmation notification appears, providing a link to the app bundle and a link to analyze it in the APK Analyzer. If the build variant you've selected is a debug build type, then the app bundle is signed with a debug key, and you can use bundletool to deploy your app from the app bundle to a connected device. If you've selected a release variant, then the app bundle is unsigned by default and you must manually sign it using jarsigner.

You need to sign your app with a release key before you can upload it to the Play Console. For more information about app signing, see Sign your app. For details about the tasks that Gradle executes for each command, open the Build window as described in the next section. For more information about Gradle and the build process, see Configure Your Build.

The window displays the tasks that Gradle executes in order to build your app, as shown in figure 3. Figure 3. The Build output window in Android Studio.
