Showing a dialog while requesting GPS location in FragmentActivity using a AsyncTask

Question

I'm having a lot of trouble with showing a dialog while getting a GPS fix :(

Code: http://pastie.org/private/5a1yclz1qt7wywafpmdckw

MyLocation code from here: https://stackoverflow.com/a/3145655/3210508

locationResult = new MyLocation.LocationResult() {
@Override
public void gotLocation(Location location)
{
    lat = location.getLatitude();
    lon = location.getLongitude();
    acc = location.getAccuracy();
    Log.i("TRIREC", "Got location: " + lat + ", " + lon + ", " + acc);
}
};
myLocation = new MyLocation();
myLocation.getLocation(Home.this, locationResult);

Error when calling above code outside of runonuithread
