java.lang.NoClassDefFoundError: com.google.firebase.FirebaseOptions

Question

I was getting this weird error on my google developer console. So i used google Cloud Test Lab to See whats really happening. turns out my app is failing on almost all devic

Answer 1

with my case: Use FCM and Google map

//for FCM
compile 'com.google.firebase:firebase-messaging:9.4.0'
//for Map
compile 'com.google.android.gms:play-services:9.4.0'

I have fixed: Removed

compile 'com.google.android.gms:play-services:9.4.0'

and Used

compile 'com.google.android.gms:play-services-maps:9.4.0'
compile 'com.google.android.gms:play-services-location:9.4.0'

It worked fine.
