Answer 1

Excluding com.google.android.gms from the offending package worked to build the project for me, but unfortunately the app would crash during initialization. The solution for me was to upgrade all firebase dependencies from 11.6.0 to 11.8.0, ie:

- compile "com.google.android.gms:play-services-base:11.6.0"
- compile "com.google.firebase:firebase-core:11.6.0"
- compile "com.google.firebase:firebase-messaging:11.6.0"
- compile "com.google.firebase:firebase-analytics:11.6.0"
- compile "com.google.firebase:firebase-ads:11.6.0"

+ compile "com.google.android.gms:play-services-base:11.8.0"
+ compile "com.google.firebase:firebase-core:11.8.0"
+ compile "com.google.firebase:firebase-messaging:11.8.0"
+ compile "com.google.firebase:firebase-analytics:11.8.0"
+ compile "com.google.firebase:firebase-ads:11.8.0"

The problem was only presenting itself when adding firebase-ads but this fixed it.
