My fellow evangelist Mark Doherty was quite busy this summer building an AIR application for Android. Now, why I am taking my time and your time to talk about his application? Because this application is an excellent resource for learning how various capabilities of the Flash Platform fall together on Android.
This application enables users to make peer2peer video calls. It uses Google Maps in 3D mode, Twitter or Facebook for authentication (we just released a new version of the Adobe ActionScript SDK for Facebook platform), and Adobe Cirrus (formerly Stratus) for sending the data from one user to another. Of course it uses the location API to place the users on the map, and it uses Mic & Camera access as well.
Mark published this application on Android Market and built a desktop version too. You can find more about Radar on Mark’s blog.
