The IDE also includes inner classes automatically. You can now add breakpoints and debug your app as you normally would.
If your APK includes native libraries. If you build the native libraries in your APK with a build ID , Android Studio checks whether the build ID in your symbol files matches the build ID in your native libraries and rejects the symbol files if there is a mismatch. If you did not build with a build ID, then providing incorrect symbol files may cause problems with debugging. If the APK and debuggable native libraries were built using a different workstation, you need to also specify paths to local debug symbols by following these steps:.
Figure 2. Providing paths to local debug symbols. You should now see the native source files in the Project window. Usually, you release applications through an application marketplace such as Google Play, but you can also release applications on your own website or by sending an application directly to a user.
Releasing through an app marketplace If you want to distribute your apps to the broadest possible audience, releasing through an app marketplace such as Google Play is ideal. Google Play is the premier marketplace for Android apps and is particularly useful if you want to distribute your applications to a large global audience.
However, you can distribute your apps through any app marketplace you want or you can use multiple marketplaces. Google Play is a robust publishing platform that helps you publicize, sell, and distribute your Android applications to users around the world. When you release your applications through Google Play you have access to a suite of developer tools that let you analyze your sales, identify market trends, and control who your applications are being distributed to. You also have access to several revenue-enhancing features such as in-app billing and application licensing.
The rich array of tools and features, coupled with numerous end-user community features, makes Google Play the premier marketplace for selling and buying Android applications. To fully leverage the marketing and publicity capabilities of Google Play, you need to create promotional materials for your application, such as screenshots, videos, graphics, and promotional text. Google Play lets you target your application to a worldwide pool of users and devices.
By configuring various Google Play settings, you can choose the countries you want to reach, the listing languages you want to use, and the price you want to charge in each country. You can also configure listing details such as the application type, category, and content rating. When you are done configuring options you can upload your promotional materials and your application as a draft unpublished application. If you are satisfied that your publishing settings are correctly configured and your uploaded application is ready to be released to the public, you can simply click Publish in the Play Console and within minutes your application will be live and available for download around the world.
If you do not want to release your app on a marketplace like Google Play, you can make the app available for download on your own website or server, including on a private or enterprise server.
To do this, you must first prepare your application for release in the normal way. Then all you need to do is host the release-ready APK file on your website and provide a download link to users.
When users browse to the download link from their Android-powered devices, the file is downloaded and Android system automatically starts installing it on the device. However, the installation process will start automatically only if the user has configured their Settings to allow the installation of apps from unknown sources.
If they don't stay in sync, your app code can't resolve the R class because it's no longer in the same package, and the manifest won't identify your activities or other components. You must always specify the package attribute in your project's main AndroidManifest. If you have additional manifest files such as for a product flavor or build type , be aware that the package name supplied by the highest-priority manifest file is always used in the final merged manifest.
For more information, see Merge multiple manifest files. One more thing to know: Although you may have a different name for the manifest package and the Gradle applicationId , the build tools copy the application ID into your app's final manifest file at the end of the build. So if you inspect your AndroidManifest.
The package attribute is where Google Play Store and the Android platform actually look to identify your app; so once the build has made use of the original value to namespace the R class and resolve manifest class names , it discards that value and replaces it with the application ID.

Find opportunities to reduce your Android app size by inspecting the contents of your app APK file, even if it wasn't built with Android Studio. Inspect the manifest file, resources, and DEX files. Compare two APKs to see how your app size changed between app versions.
Install and run your apps faster than with a physical device and simulate different configurations and features, including ARCore, Google's platform for building augmented reality experiences. Powered by Gradle, Android Studio's build system allows you to customize your build to generate multiple build variants for different devices from a single project.
The built-in profiling tools provide realtime statistics for your app's CPU, memory, and network activity. Identify performance bottlenecks by recording method traces, inspecting the heap and allocations, and see incoming and outgoing network payloads. See the Android Studio release notes.
