What is apk bundle
An App Bundle is a publishing format introduced by Google for Android apps. It is designed to optimize the delivery of apps to users by reducing the size of the app and ensuring that users download only the code and resources they need for their specific device configuration.
Key Features of Android App Bundle (.aab):
Smaller App Size:
Instead of uploading a single APK for all devices, developers upload an App Bundle.
Google Play then generates optimized APKs for each device configuration (CPU architecture, screen density, language, etc.).
Users download only the necessary components, reducing app size.

Dynamic Feature Modules (Optional):
Developers can split features into separate modules that are downloaded on demand.
This is useful for large apps where not all users need every feature.

No More Multiple APKs:
Previously, developers had to upload separate APKs for different device types (e.g., ARM, x86, HD, 4K).
With App Bundles, Google Play handles this automatically.
