Android chat app in the cloud
summary
Builds a working Android chat client and deploys a backend with App Engine + Cloud Endpoints and Cloud Datastore using the Mobile Backend Starter wizard; generates client libraries, sets Android and web client IDs for OAuth, and enables push via Google Cloud Messaging v2. The demo shows device registration IDs, a broadcast receiver + wakeful service to handle notifications, an async handler/callback pattern with a retained fragment for lifecycle, and claims the setup scales 1 to 1,000,000 users and deploys successfully.
