Added the "old" GCM listener to get compatibility with GCM back

[Gp2mv3]

Maybe not the best solution in term of code redundancy but it works.
What do you think ?

@Gp2mv3 When I install version 3.1.1 through npm or yarn RNPushNotificationListenerServiceGcm does not exist, however I see it in the repo on master branch. Should bumping the version solve the problem?

Hi @Gp2mv3. Any insights on my above question?

It still crashes for me when receiving a GCM push notification. I'm using the latest commit containing this PR (yarn add https://github.com/zo0r/react-native-push-notification#aaf2d19925db4666d6018c0ab1ff0d7d4c90a21d).

@silentlight 3.1.1 is a tag, not the latest master. You need to point package.json to latest master commit manually so replace:
"react-native-push-notification": "3.1.1" (3.1.1 tag)

with:
"react-native-push-notification": "git+https://github.com/zo0r/react-native-push-notification.git#aaf2d19925db4666d6018c0ab1ff0d7d4c90a21d" (aaf2d19925db4666d6018c0ab1ff0d7d4c90a21d is the lates commit atm)

& yarn install :)

I'm with @stpch, I'm still crashing when receiving notifications while app is in the foreground. Have this branch checked out even:

"react-native-push-notification": "https://github.com/zo0r/react-native-push-notification.git#fixGcm",

It would appear that the firebase and GCM dependencies in build.gradle cannot coexist:

compile "com.google.android.gms:play-services-gcm:$googlePlayServicesVersion"
compile "com.google.firebase:firebase-messaging:$firebaseVersion"

after deleting the firebase entry and any classes that depend on it I was able to rebuild and no more crashes.

Looks like forking and reverting #717 is the only option to support GCM.

Note: GCM is 100% deprecated, only do this if you know what you're doing and why.
