While implementing app-app calling with Sinch, I need to integrate push notification using firebase cloud messaging(FCM). As there is no doc available so I followed the same process like GCM but when I called
mSinchClient.setSupportManagedPush(true);
it is throwing exception missing GCM exception
com.sinch.android.rtc.MissingGCMException: Can't enable managed push as this depends on GCM, which is not available on this device
We currently do not support FCM for managedpush if you cant use GCM use this to implement the push methods your self https://www.sinch.com/docs/voice/android/#pushnotificationssentviayourapplicationserver
