While this does work for Android 2.x, since there is no BluetoothAdapter class in the 1.5 API, it does not compile correctly. Also, this pops up an alert dialog that asks if the user wants to turn bluetooth on or off, but it does nothing without user interaction, which is what I'm trying to accomplish. Thank you for the response, I'm just do not think it will do what I need it to.
