Android Cloud to Device Messaging (commonly referred to as Cloud to Device Messaging), or C2DM, is a defunct mobile notification service that was developed by Google and replaced by the Google Cloud Messaging service. It enabled developers to send data from servers to Android applications and Chrome extensions. C2DM originally launched in 2010 and was available beginning with version 2.2 of Android.[1] On June 27, 2012, Google unveiled the Google Cloud Messaging service aimed at replacing C2DM, citing improvements to authentication and delivery, new API endpoints and messaging parameters, and the removal of API rate limits and maximum message sizes.[2] Google announced official deprecation of the C2DM service in August 2012, and released documentation to assist developers with migrating to the new service. The C2DM service was discontinued for existing applications and completely shut down on October 20, 2015.[3]
