Google Cloud Messaging is a service that allows messages to be sent from a server to your device. This is really useful for a device getting notifications like in a messaging app. This makes it curious for Netflix to add support for GCM in the latest version of their app.
You can see this in their manifest, which makes references to the GCM intent actions:
Looking at the manifest permissions, it again shows this functionality has just been added to their app:
The files themselves don’t offer much guidance, however. The
GCMIntentService to be another way to cache the tiles that appear in the
PreAppInitTilesReceiver. So perhaps Netflix will use this new feature to make sure TV and movie thumbnails are as fast as possible. What it doesn’t appear to have, unfortunately, is any reference for recommendations, Android TV’s way of surfacing content you might want to watch.
You can sideload the newest version of Netflix for Android TV at APK Mirror, or just wait until your device gets the update.
