"more than one library with package name 'com.google.android.gms'" on Ionic

Question

I'm getting an error when trying to build my ionic app for android. It throws an error: Error: more than one library with package name 'com.google.android.gms' and I can't figure out what combination of plugins is causing it. What plugins are causing the issue and what can I do about it? Thanks!

Answer 1

Woo! I was able to fix it.

1. Create a build-extras.gradle file in the same folder as your build.gradle.

2. Fill it with this:

   configurations { all*.exclude group: 'com.android.support', module: 'support-v4' all*.exclude group: 'com.google.android.gms', module: 'play-services-analytics' }

The second line is related to this error, the first line fixes a similar issue.
