BluetoothAdapter.getDefaultAdapter() throwing RuntimeException while not in Activity

When I'm trying to get default bluetooth adapter while i'm NOT in Activity, but in TimerTask (created inside Service) by using:

BluetoothAdapter.getDefaultAdapter();

I get the following exception:

Exception while invoking java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare()

My application do not have any activity - so is there any possibility to get this adapter away from Activity?
