The Bluetooth (or WiFi) range is to short to do something exiting with it so build a solution to have best of both wolds.
You need a BT module, Xbee/Wi232 or any other long range wireless connection.
Build it like the schematic in the attached picture.
Now connect with your Android device to the BT module and see a Long Range Android communication system.
And the good thing is that if you have a third Xbee/Wi232?.. module you can still use your PC with QG to connect
