This document summarizes a presentation about Android push notifications. It discusses using push notifications and remote content management to update 280 devices with intermittent connectivity. It evaluates solutions like ZeroMQ, Redis, a custom queue management system, and Google Cloud Messaging (GCM) push notifications. GCM is chosen as the easiest option. The services architecture is described using components like Apache Cordova, BusyBox, SuperSU, and a JavaScript media player that can be updated through push notifications and intents.
