gcm-server
A Google Cloud Messaging (GCM) server library for 3rd party server usage.
Google Cloud Messaging for Android (GCM) is a service that helps developers send data from servers to their Android applications on Android devices. The service provides a simple, lightweight mechanism that servers can use to tell mobile applications to contact the server directly, to fetch updated application or user data. The GCM service handles all aspects of queueing of messages and delivery to the target Android application running on the target device.
The origin source code of the gcm Google Cloud Messaging for Android library was hosted by Google Code. This project or rather source code was forked from the corresponding GitHub repository of Google GCM.
