[android] Android: Getting "Manifest merger failed" error after updating to a new version of gradle

I'm not using different versions of libraries and got the same error, it's happened after remove buildToolsVersion in AS RC 1, but adding tools:node="replace" did the trick, just add this into your manifest.xml inside <application ..../> block:

<meta-data 
 tools:node="replace"
 android:name="com.google.android.gms.version"
 android:value="@integer/google_play_services_version" />
