Migrate your client Apps on Android to FCM
Google Cloud Messaging (GCM) has been deprecated and is integrated with Firebase Cloud Messaging (FCM). Google will turn off most GCM services by April 2019.
The Push Notifications on IBM Mobile Foundation has been updated to use the FCM endpoints. For now, the existing applications using GCM services will continue to work.
However, the Push Notifications service will pull out support for GCM projects soon.
If you are using a GCM project, then migrate the GCM client apps on Android to FCM at the earliest.
Note that there will be no change in the SDK and the client app would behave as expected. After migrating to FCM, update your project to use FCM credentials instead of the old GCM credentials.
We recommend the developers to upgrade at the earliest.
