Keeping app content fresh is important to retaining users. And it’s easy with the popular Google Cloud Messaging for Android, by sending lightweight messages to your apps installed on Android devices anywhere in the world.

Push messages from your backend servers to tell your apps that there's new content for the user, or other data to sync.

You can use Google Cloud Messaging for two way messaging too. Another possibility is to improve the experience for users with multiple devices, by syncing content through the cloud so users have the same content on all their devices.

Google Cloud Messaging lets your users stay in sync with your service without draining the user’s battery, as there's no need for your apps poll a server to discover new content. Best of all, Google Cloud Messaging is available for free and there are no quotas.
