Android Instant App : Feature module : The module cannot be android library

Question

I started converting my app to support instant feature , following the Google IO tutorial . I got the build running correctly. I've disabled aapt2 and enableNewResourceProcessing as i was running into build errors . The module builds without errors after disabling those two flags but when i go to edit configuration of the base Feature of the app i get The module cannot be android library .

Does anyone know what causes this issue. I'm using com.android.feature plugin in the feature module's build along with build flavours and build types .

Answer 1

A feature module is treated as a library. It doesn't have an application ID. So, "The module cannot be android library" error is generated.

Answer 2

The problem I was facing was that there was a build configuration for the instant feature as well. Since each instant feature is considered as an android library, Studio throws errors saying module cannot be android library . To solve this i simply removed the build configuration via

Run -> Edit configuration -> Click on - button

Keep your base app module configuration and delete all other feature configurations.

Answer 3

Don't run your feature . Run your instantapp instead and set feature URL in it:

Run -> Edit Configurations -> Android App -> instantapp -> General -> Launch Options -> Launch = URL -> URL = https://example.com/my_feature
