Firebase Messaging on Android suddenly started crashing when message received

Question

Currently using react native, react-native-firebase, and react-native-push-notification. Everything was fine until suddenly today firebase messaging started causing the app to crash. The error message is the following:

    Process: com.packagename, PID: 30087     java.lang.AbstractMethodError: abstract method "com.google.android.gms.tasks.Task com.google.firebase.iid.WithinAppServiceBinder$IntentHandler.zza(android.content.Intent)"         at com.google.firebase.iid.WithinAppServiceBinder.zza(com.google.firebase:firebase-iid@@20.2.2:9)         at com.google.firebase.iid.zzaw.zza(com.google.firebase:firebase-iid@@20.2.2:30)         at com.google.firebase.iid.zzaw.onServiceConnected(com.google.firebase:firebase-iid@@20.2.2:59)         at android.app.LoadedApk$ServiceDispatcher.doConnected(LoadedApk.java:2067)         at android.app.LoadedApk$ServiceDispatcher$RunConnection.run(LoadedApk.java:2099)         at android.os.Handler.handleCallback(Handler.java:883)         at android.os.Handler.dispatchMessage(Handler.java:100)         at android.os.Looper.loop(Looper.java:237)         at android.app.ActivityThread.main(ActivityThread.java:8016)         at java.lang.reflect.Method.invoke(Native Method)         at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:493)         at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1076) 

The error occurs when a notification is received, but does not trigger a data message. In addition, the notification is received and processed before causing the crash.

I thought the error might have been caused by changing the react-native-firebase/app version, so I reverted my project on git to that of a previous, working version. However, I still get the same error after cleaning and rebuilding. It also occurs even if there are no notification listeners set up on the react native side, although I'm not sure what that entails for the actual native code. What could possibly be the problem? I'm using versions of react-native-firebase/messaging (7.1.5) and react-native-firebase/app (7.2.0) that were previously functional.

Edit 07/09/2020: We have released firebase-iid and firebase-messaging versions 20.2.3 with a fix for this issue, please upgrade to the latest versions.

[Firebaser here] It looks like yesterday's releases of firebase-messaging and firebase-iid contain a bug which can cause this crash. We are working hard on a fix.

For now the best thing to do is to use the versions released on June 18th: https://firebase.google.com/support/release-notes/android#2020-06-18

• com.google.firebase:firebase-messaging:20.2.1
• com.google.firebase:firebase-iid:20.2.1

We are working on a fix and hope to have a new release out soon. When we do I will update this answer and the release notes will be available here: https://firebase.google.com/support/release-notes/android

We tried adding firebaseMessagingVersion = "20.2.1" into the ext section in the root project android/build.gradle which fixed it for us. We looked into the safeExtGet method and found that it would try to extract the top level variable from the root project file.

By doing it in this way we didn't need to touch the node modules.

ext {         googlePlayServicesVersion = "16.+"         firebaseVersion = "17.3.4"         firebaseMessagingVersion = "20.2.1"     }
