Description

Would be nice if Obtainium could also support installing App Bundles.

I'm not sure how feasible this is, since I think the bundle needs to be split & combined to an apk to be installable, which would require resigning the resulting apk. If Obtainium were to do this using a local signing key it should also validate the signature of the aab itself.

Here's an example of a GitHub release with an app bundle attached: https://github.com/vector-im/element-x-android/releases/tag/v0.1.2

Contributor guide

Research direction
Research how Obtainium currently downloads APKs from releases, then investigate how to handle .aab files. Understand the Android App Bundle format and tools like bundletool to convert .aab to APKs for installation. Consider signing requirements: Obtainium would need to generate a local signing key or use a provided one to sign the resulting APK(s). Look into existing implementations or libraries that perform this conversion in Flutter/Dart.
