Bluetooth Chat Demo

The app should be run on two separate devices. When started, it will display two lists: one for discovered devices and one for paired devices. Clicking on an entry in either list will cause the app to attempt to connect to that remote device. If the remote device is running this app, the connection will succeed and both devices will then display the chat UI and text can be sent and received. Clicking on "Done" on either device will terminate the session and both devices will return to the original screen.

Bluetooth Chat Demo is rock solid. It handles all network activity (connection set up as well as chat communications) on background threads. Activities and threads are managed carefully, with no memory or thread leaks. Displays are maintained across device rotations, as are chat connections (even the official Android Bluetooth chat demo loses its chat connection when the device is rotated).
