Building a Release-Ready APK 4:25 with Ben Jakuben. We need to digitally sign and export our app, but fret not, it is easier than it sounds! And then click on Generate Signed APK. So, first select the module that has your app code. For different apps we could generate a new key store for each app. On the Generate Signed APK Wizard window, select a keystore, a private key, and enter the passwords for both. Then click Next. Select a destination for the signed APK, select the build type, choose the product flavor, and click Finish. Configure the build process to automatically sign your APK.
The second Android 11 Developer Preview is now available, test it out and share your feedback.
Android Studio sets up new projects to deploy to the Android Emulator ora connected device with just a few clicks. Once your app is installed,you can use Apply Changes to deploy certain code and resourcechanges without building a new APK.
To build and run your app, follow these steps:
Change the run/debug configuration
When you run your app for the first time, Android Studio uses a default runconfiguration. The run configuration specifies whether to deploy your app froman APK or an Android App Bundle, the module to run,package to deploy, activity to start, target device, emulator settings, logcatoptions, and more.
The default run/debug configuration builds an APK, launches the defaultproject activity, and uses the Select Deployment Target dialog for targetdevice selection. If the default settings don't suit your project or module,you can customize the run/debug configuration, or even create a new one, atthe project, default, and module levels. To edit a run/debug configuration,select Run > Edit Configurations. Formore information, see Create andEdit Run/Debug Configurations.
Change the build variant
By default, Android Studio builds the debug version of your app, which isintended for use only during development, when you click Run.
To change the build variant Android Studio uses, select Build> Select Build Variant in the menu bar.
For projects without native/C++ code, the Build Variants panel has twocolumns: Module and Active Build Variant. The Active Build Variantvalue for the module determines which build variant the IDE deploys to yourconnected device and is visible in the editor.

Figure 1. The BuildVariants panel has two columns for projects that do not have native/C++code
To switch between variants, click the Active Build Variant cell for a moduleand choose the desired variant from the list field.
For projects with native/C++ code, the Build Variants panel has threecolumns: Module, Active Build Variant, and Active ABI. The ActiveBuild Variant value for the module determines the build variant that the IDEdeploys to your device and is visible in the editor. For native modules, theActive ABI value determines theABI that the editor uses, butdoes not impact what is deployed.

To change the build variant or ABI, click the cell for the Active Build Variantor Active ABI column and choose the desired variant or ABI from the list.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 alldependent rows.

By default, new projects are set up with two build variants: a debug and releasevariant. You need to build the release variant to prepare your app for publicrelease.
To build other variations of your app, each with different features or devicerequirements, you can define additional build variants.
Build your project
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.
Note: Android Studio requires AAPT2 to build app bundles, which isenabled for new projects by default. However, to make sure it is enabled onexisting projects, include android.enableAapt2=true in yourgradle.properties file and restart the Gradle daemon by running ./gradlew--stop from the command line.
Table 1. Build options in the Build menu.
Note: The Run button builds an APK with
testOnly='true' ,which means the APK can only be installed via adb (which Android Studio uses). If you wanta debuggable APK that people can install without adb, select your debug variant and clickBuild Bundle(s) / APK(s) > Build APK(s).
For details about the tasks that Gradle executes for each command, open the Build window asdescribed in the next section. For more information about Gradle and the build process, seeConfigure Your Build.
Monitor the build process
You can view details about the build process by clicking View > Tool Windows > Build (or by clicking Build in the tool window bar). 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
If your build variants use product flavors, Gradle also invokes tasks to build those product flavors. To view the list of all available build tasks, click View > Tool Windows > Gradle (or click Gradle in the tool window bar).
If an error occurs during the build process, Gradle may recommend some command-line options to help you resolve the issue, such as
--stacktrace or --debug . To use command-line options with your build process:
Gradle applies these command-line options the next time you try building your app.
Apply Changes
In Android Studio 3.5 and higher, Apply Changes lets you push code and resourcechanges to your running app without restarting your app—and, in somecases, without restarting the current activity. This flexibility helps youcontrol how much of your app is restarted when you want to deploy and testsmall, incremental changes while preserving your device's current state. ApplyChanges uses capabilities in the Android JVMTI implementation that are supported on devices running Android 8.0 (API level 26) or higher. Tolearn more about how Apply Changes works, seeAndroid Studio Project Marble: Apply Changes.
Requirements
Apply Changes actions are only available when you meet the following conditions:
