Android Asynctask & Locationlistener

I created a class GPSController. The onReceive is called every Minute. I want to get the current GPS Data with the GPSListener in my AsyncTask. But the onLocationChanged Method i

Solution 1:

This class provide current lat , log and In onLocationChanged method you can call AsyncTask called every Minute.

publicclassGPSTrackerextendsServiceimplementsLocationListener {

        privatestaticfinalStringTAG= GPSTracker.class.getSimpleName();
        privatefinal Context mContext;

        // flag for GPS statusbooleanisGPSEnabled=false;

        // flag for network statusbooleanisNetworkEnabled=true;

        // flag for GPS statusbooleancanGetLocation=false;

        Location location; // locationdouble latitude; // latitudedouble longitude; // longitude// The minimum distance to change Updates in metersprivatestaticfinallongMIN_DISTANCE_CHANGE_FOR_UPDATES=10; // 10 meters// The minimum time between updates in millisecondsprivatestaticfinallongMIN_TIME_BW_UPDATES=1000 * 60 * 1; // 1 minute// Declaring a Location Managerprotected LocationManager locationManager;

        publicGPSTracker(Context context) {
            this.mContext = context;
            getLocation();
        }
