Most Android phones will not accept a random Bluetooth connection. They require basic keycode pairing.

So theoretically an app like that should not work. If it does, it would be a nasty hack and would likely be fixed eventually. And if you did this without someone's permission they would be very angry.


However, assuming you had permission and assuming you have paired properly, you can send a image as a byte array over an RFComm channel just like you would send any serializable object.

The BluetoothChat example that comes with the Android SDK shows how to do this with a String. But you can apply the technique to any object that you can convert into bytes.
