What are AAB and APK Files?
An AAB file is a publishing format that includes all your app's compiled code and resources, and defers APK generation and signing to Google Play. Google Play uses your app bundle to generate and serve optimized APKs for each device configuration, so only the code and resources that are needed for a specific device are downloaded to run your app. You no longer have to build, sign, and manage multiple APKs to optimize support for different devices, and users get smaller, more-optimized downloads.
An APK file is a package file that contains all of a program's code (such as .dex files), resources, assets, certificates, and manifest file. It is the file format used by the Android operating system, and a number of other Android-based operating systems for distribution and installation of mobile apps, mobile games and middleware. A file using this format can be built from source code written in either Java or Kotlin . APK files can be generated and signed from Android App Bundles.
What are the Benefits of Using AAB Files?
Using AAB files has several benefits for app developers and users, such as:
Reducing app size: By generating optimized APKs for each device configuration, Google Play can reduce the size of your app downloads by an average of 20%. This means faster downloads, less storage space used, and lower data costs for users.
Improving app quality: By delivering only the code and resources that are needed for each device configuration, Google Play can reduce the complexity of your app testing and maintenance. This means fewer bugs, crashes, and compatibility issues for users.
Enabling advanced features: By using AAB files, you can also optionally take advantage of Play Feature Delivery , which allows you to add feature modules to your app project. These modules contain features and resources that are only included with your app based on conditions that you specify, or are available later at runtime for download Using the Play Core Library. For example, you can create an instant app version of your app, or deliver large assets such as game levels or videos on demand.
What are the Challenges of Using AAB Files?
While AAB files offer many advantages, they also come with some challenges and limitations that you should be aware of, such as:
Compressed download size restriction: When you use the app bundle format to publish your app, you must ensure that the total size of the compressed APKs required to install your app (for example, the base APK + configuration APKs) is no more than 150 MB. Any subsequent downloads, such as downloading a feature module (and its configuration APKs) on demand, must also meet this compressed download size restriction. Asset packs do not contribute to this size limit, but they do have other size restrictions. If you encounter this error when publishing your app bundle, you need to reduce compressed APK download sizes by following some tips and resources provided by Google Play. If you need to support larger app sizes, you can use Play Asset Delivery or Play Feature Delivery.
Testing and debugging challenges: Because Google Play generates the APKs that are installed on user devices, you need to use different strategies to test how Google Play delivers your app to users. For example, you can use internal app sharing to quickly share an app bundle and test downloads of your app from Google Play. You can also use the bundletool command line tool to generate APKs from your app bundle and deploy them to a connected device.
Compatibility issues with some devices and platforms: Some devices and platforms may not support installing or running apps from app bundles, such as Android Instant Apps, Wear OS, and Android TV. For these cases, you need to provide a legacy APK along with your app bundle.
