We just tried to update our Android build to the new push notification system. Unfortunately, as the push notification system uses Firebase we can't use it because Firebase including all depending Android libraries adds almost 20.000 dex references which is way too much for our projects to successfully build an APK. (We need around 63k references for google play, facebook and heyzap/admob already).
Anyway, as the old PlayfabUnityAndroid plugin makes to much troubles we decided giving the Prime31 Google Cloud Messaging plugin a try. To make it short, works perfect at the moment. Using the replacement functions we get the title and message values sent from playfab perfectly displayed.
GoogleCloudMessaging.setPushNotificationAlternateKey( "subtitle", "default" ); GoogleCloudMessaging.setPushNotificationAlternateKey( "title", "gcm.notification.title" );Just for your information.
