Type androidx.appcompat.resources.R$dimen is defined multiple times

Question

We have a React Native app where after upgrading to Android Studio 3.6.1 and Gradle plugin 3.6.1 we are seeing this compilation error:

Type androidx.appcompa         


        

Answer 1

My errors were similar, with a "is defined multiple times" message.

I solved it by downgrading the Gradle plugin to 3.5.0, running the app — or at least trying to — then upgrading to Gradle plugin 3.6.2 again.

I am not sure why, but this seemed to have cleared some caches or dependencies I was not aware of.

Removing ~/.gradle or android/.gradle did not help.
