I have a AsyncTask where it checks for the Accelerometer data. When ever i detects that Accelerometer is giving larger values i need to start the GPS recording. 

private LocationManager mlocManager;
private GPSLocationListener mlocListener;
..
mlocManager = (LocationManager)context.getSystemService(context.LOCATION_SERVICE);
mlocListener = new GPSLocationListener();
..
mlocManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 10000, 100, mlocListener); 
mlocManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 10000, 100, mlocListener);

    AsyncTask doesn’t run on the Looper thread and hence the problem, You may want to use Handlers as they run with the Looper thread and hence such errors wont occur.
