private BluetoothAdapter bluetoothAdapter = null;
bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();

void ChangeDeviceName(){
 Log.i(LOG, "localdevicename : "+bluetoothAdapter.getName()+" localdeviceAddress : "+bluetoothAdapter.getAddress());

For some devices Method:1 won't work.  use system settings.

Settings.System.putString(context.getContentResolver(), “device_name”, “user name”);
