In this paper we do a case study of the state of the art of push messaging for Android. We examine a technology called C2DM (Cloud to Device Messaging) and how well it integrates with cloud computing. In our investigation we look at the performance of the library, integration with Google App Engine and also the development tools including the API. We create an application using C2DM and do initial performance tests. In an attempt at making development of applications for push messaging on the Android platform simpler, and C2DM in particular, we introduce a new open source library we call Simple-C2DM.
