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.
This origin code has been taken over from the gcm Google Cloud Messaging for Android library hosted by Google Code. The assumed and advanced gcm-server can be used for Implementing GCM Server purpose in the context of a Maven based Java project.
