requestLocationUpdates not working from a Thread

Hi I'm trying to requestLocationUpdates from a Thread other than the UI Thread, I'm getting a RuntimeExeption in the following line:

// request location updates using Cellular 
lm.requestLocationUpdates(
    LocationManager.NETWORK_PROVIDER,
    0,
    0,
    locationListener);

Then reading the documentation it says that it Throws:

IllegalArgumentException  if provider is null or doesn't exist on this device 
IllegalArgumentException  if listener is null 
RuntimeException  if the calling thread has no Looper 
SecurityException  if no suitable permission is present

So it seems to be that my thread has no Looper, but the problem is that I don't know what they mean by a "Looper". Thanks in advance!

U can try this :

lm.requestLocationUpdates(
    LocationManager.NETWORK_PROVIDER,
    0,
    0,
    locationListener,
    Looper.myLooper()
);

Change your run() code to 

@Override
public void run()
{
    Looper.prepare();

    // The rest of your code

    Looper.loop();
}
