onPause to stop LocationManager

Question

I think I’m doing this right?

I have this code which starts looking for my GPS location via a MyLocationListener method not displayed here, that works but I want to stop the locationManager onPause, I think or whenever this activity is not current, but I can’t get the removeUpdates code to resolve.

locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);        
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, MINIMUM_TIME_BETWEEN_UPDATES, MINIMUM_DISTANCE_CHANGE_FOR_UPDATES, new MyLocationListener());

and then,

@Override 
public void onPause()
{
    super.onPause();
    locationManager.removeUpdates(MyLocationListener);
}

“MyLocationListener” wont resolve, I’ve also tried “this” and,

locationManager.removeUpdates((LocationListener) this);

Which resolves but gives me a “Cannot Pause” error at runtime.

I had a similar question: Having some trouble getting my GPS sensor to stop

you might need to define a LocationListener that is the same for the one that is started and the one that is ended.

Try:

LocationListener mlocListener; 

under the class name and then use the following in your onCreate method:

mlocListener = new MyLocationListener();

And use the above mlocListener for the whole class.

So have your class look something like this:

public class SomeClass extends Activity {
    LocationManager mlocManager;
    LocationListener mlocListener; 

@Override
protected void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.screenlayout);
    mlocManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
    mlocListener = new MyLocationListener();
    mlocManager.requestLocationUpdates( LocationManager.GPS_PROVIDER, 0, 0, mlocListener);
}

@Override
public void onPause(){
    mlocManager.removeUpdates(mlocListener);
    super.onPause();
}
