C2DM (Android Cloud 2 Device Message) was announced at Google IO 2010. The feature was introduced to relieve the applications from polling cloud resources e.g email.
Fortunately, C2DM has an API, so I thought I’d create a platform off the C2DM infrastructure. This involved developing a back-end application server (I’m running on Google App Engine) and an Android client library that Android developers can utilities to enhance their application (Android 2.2+ required) with push messaging.
TheTok-Toki service (named after the Tok-Tokkie beetle, indigenous to South Africa, known for tapping on the ground to communicate to other beetles). is hosted here.
