Android Instant App : Default Activity not found

Question

This seems to be manifest merging error. I\'m trying to port existing code to instant app module. What I\'ve tried is :

1. Changed main app module to baseFeatureM

Answer 1

I figured out, that the Manifest merger failed with the Firebase plugin in the base module.

Option 1:

I fixed this by adding following to the base modules 'AndroidManifest.xml'.

Don't forget to replace mypackage.

Option 2:

Copy the whole ... tag into app modules AndroidManifest.xml
