[error] (guidemate/android:rGenerator) Error: more than one library with package name 'com.facebook.soloader'
com.facebook.soloader(as expected), but this library is probably needed somewhere, so I don't know if this is really an option.
more than one library with package name ...: It seems to have been a problem in gradle, too. Here, it is suggested that the problem was fixed in a newer gradle version: https://stackoverflow.com/questions/51024717/error-more-than-one-library-with-package-name-android-support-graphics-drawabl
Alright so I was able to confirm this, firebase-common in version 19.3.0 has this additional attribute:
which is not present in version 19.0.0, and when I override which version to use all seems fine?
Is there some settings somewhere that I can tune to enable the support for tools:targetApi ?
