It is so simple to fix guys.If you are using player-services and firebase both in your project make sure that you don't import all the available services in the google.Just import the APIs what you actually need. For example:

 compile 'com.google.firebase:firebase-messaging:9.2.0'
 compile 'com.google.android.gms:play-services:9.2.0'

Doing this way it can give you noclassdeffounderror .To fix this

remove play-services and sync your project. If you have dependency like using ads or maps in your app then define the specific API. like:

compile 'com.google.android.gms:play-services-maps:9.2.0'

Note: Maximum don't try to use multiDexEnabled true. This should be your last step to fix something.

Hope this is helpful.
