Answer 1

Had the same issue while integrating firebase. For my case, it was caused by version mismatch.

on the app gradle, i had:

ext {
    PLAY_SERVICES_VERSION = '10.2.0'
}
dependencies {
    compile "com.google.android.gms:play-services-maps:$PLAY_SERVICES_VERSION"
    compile "com.google.android.gms:play-services-location:$PLAY_SERVICES_VERSION"
    compile "com.google.android.gms:play-services-places:$PLAY_SERVICES_VERSION"
    compile 'com.google.firebase:firebase-database:10.0.1'
}

the firebase dependancy was added through the integrated firebase plugin in Android studio. When i matched the versions, it worked.
