Question

I am using LocationManager to get a single location fix:

public class MyActivity extends Activity {
    private LocationManager lm;
    private ProgressDialog myDialog;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
        LocationListener ll = new MyLocationListener();
        lm.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 1, 1, ll);
        myDialog = ProgressDialog.show(this, null , "Determining Your Location", true);
    }

    class MyLocationListener implements LocationListener {
        public void onLocationChanged(Location location) {
            if (location != null) {
                ...

                lm.removeUpdates(this);
                myDialog.dismiss();
            }
        }
    }
}

As this stands listening for a location could potentially go on forever if a location fix cannot be found. I want to add some robustness to my code by ceasing to listening for a location after 60 seconds, and displaying an error to the user to saying that their location could not be determined.

How can I do this?

Answer 1

One way would be to use a Handler and use postDelayed after 60 sec to stop the listener.
