Google Projects for Android: C2DM

Android Cloud to Device Messaging Framework

Android Cloud to Device Messaging (C2DM) is a service that helps developers send data from servers to their 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 C2DM service handles all aspects of queueing of messages and delivery to the target application running on the target device.

Note: Android C2DM is available to all developers. To use C2DM with your Android applications, go to the signup page to request access.
