[android-developers] Help with GPS Provider Switch

 

Hey,

 

Right now when trying to get a user location I start with the GPS Provider. I have a timer set for 30 seconds, If a location is not found in 30 seconds the timer goes off and stops that location request. When that happens I move to the Passive Provider. After 30 seconds if a location is not found I stop the location request and move to the Network Provider.

 

My issue is that when the network provider gets called it never does anything. If I start with the network provider it goes off just fine and returns a location back to me. Below is the code I am trying to use:

 

gpsTimer.schedule(new TimerTask(){

                  @Override

                  public void run() {

                       

                        startPassive();

                       

                       

                  }

            }, 30000);

           

            currentTimer = "GPS";

            locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);

 

private void startPassive(){

           

            locationManager.removeUpdates(locationListener);

           

            //Now we want to try for a Passive Fix

            currentTimer = "Passive";

            passiveTimer.schedule(new TimerTask(){

 

                  @Override

                  public void run() {

                        startNetwork();

                  }

                 

            }, 30000);

            Looper.prepare();

            Looper.myLooper().quit();

            locationManager.requestLocationUpdates(LocationManager.PASSIVE_PROVIDER, 0, 0, locationListener);

 

private void startNetwork(){

            locationManager.removeUpdates(locationListener);

            currentTimer = "Network";

            Looper.prepare();

            Looper.myLooper().quit();

            locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);

 

any help or suggestions would be greatly appreciated. Thank so much in advance.
