Answer 1

Rather than downgrade or upgrade library, it would better to exclude one or more of the same class from different versions. For example, if you know from which module the class is from, you can use:

compile('com.google.android.gms:play-services-auth:15.0.0') {
    exclude group: 'com.google.android.gms', module: 'module.of.dependecy,withconfllict'
}

Answer 2

I solved by upgrading all the firebase dependencies on build.gradle from 15.0.0 to 15.0.2 where available.

Go to https://firebase.google.com/docs/android/setup for latest versions available and note that latest version for com.google.firebase:firebase-ads is 15.0.0 and latest version for com.google.firebase:firebase-messaging is 15.0.2

Answer 3

Delete assets folder entry in the android studio (not from actual folder location). Then do a clean build.
