I'm trying to implement Firebase Cloud Messaging (FCM) in my application. I added following dependency in Build.gradle and tried to build a release build variant.

compile 'com.google.firebase:firebase-messaging:15.0.0'

Build.gradle

dependencies {
   compile 'com.google.firebase:firebase-core:15.0.0'
   compile 'com.google.firebase:firebase-messaging:15.0.0'
}
apply plugin: 'com.google.gms.google-services'

Once I tried to build a 'debug' variant it worked fine and Firebase messaging works without any errors. But when I try to build 'release' built varient it outputs following error.

Warning:com.google.firebase.messaging.zza: can't find referenced class android.graphics.drawable.AdaptiveIconDrawable

Can anyone help me with this. Really appreciate your comments. Thanks

Add this progurd rule in

progurd-rules.pro

-dontwarn com.google.firebase.messaging.**

generate the SHA key in release mode and then add it in the firebase and then again download the json file and replace it with your old one in application.

This happens because of the warning comes from the progurd-rules.pro. Use -dontwarn option to ignore it.
