The Parse library provides push notifications by using Google Cloud Messaging (GCM) if possible. On devices that do not support GCM (such as the Amazon Kindle Fire), Parse will use a background service that maintains a persistent connection to the Parse Cloud to deliver pushes. This allows Parse Push to work on all devices running Android 2.2 or higher.


Some push features are available only for pro users.
