Question

wanted add in this method 
 
private void getCurrentLocation() { 
 
     //Creating a location object 
 
     if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) { 
 
      // TODO: Consider calling 
 
      // ActivityCompat#requestPermissions 
 
      // here to request the missing permissions, and then overriding 
 
      // public void onRequestPermissionsResult(int requestCode, String[] permissions, 
 
      //           int[] grantResults) 
 
      // to handle the case where the user grants the permission. See the documentation 
 
      // for ActivityCompat#requestPermissions for more details. 
 
      return; 
 
     } 
 
     Location location = LocationServices.FusedLocationApi.getLastLocation(googleApiClient); 
 
     if (location != null) { 
 
      //Getting longitude and latitude 
 
      longitude = location.getLongitude(); 
 
      latitude = location.getLatitude(); 
 

 
      //moving the map to location 
 
      moveMap(); 
 
     } 
 
    }

Answer 1

그냥 자바 클래스를 Timer

int delay = 5000; // delay for 5 sec. 
int interval = 30000; // iterate every 30 sec. 
Timer timer = new Timer(); 

timer.scheduleAtFixedRate(new TimerTask() { 
     public void run() { 
      getCurrentLocation // Your method from above .. 
     } 
    }, delay, interval); 

Answer 2

LoactionListener mLocationListener; 
double lat,lng; 


inside your OnCreateMethod : 




mLocationListener = new LocationListener() { 
      @Override 
      public void onLocationChanged(Location location) { 
       lat = location.getLatitude(); 
       lng = location.getLongitude(); 

      } 

      @Override 
      public void onStatusChanged(String s, int i, Bundle bundle) { 

      } 

      @Override 
      public void onProviderEnabled(String s) { 

      } 

      @Override 
      public void onProviderDisabled(String s) { 

      } 
     }; 



if (mLocationManager.isProviderEnabled(LocationManager.GPS_PROVIDER) || mLocationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)) { 
      try { 

       if (ActivityCompat.checkSelfPermission(getApplicationContext(), android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(getApplicationContext(), android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) { 
        // TOD 
        // ActivityCompat#requestPermissions 
        // here to request the missing permissions, and then overriding 
        // public void onRequestPermissionsResult(int requestCode, String[] permissions, 
        //           int[] grantResults) 
        // to handle the case where the user grants the permission. See the documentation 
        // for ActivityCompat#requestPermissions for more details. 


        // Not implementing Permission Request Measures as User Should not know he is being tracked 

       } 


       Criteria c = new Criteria(); 
       c.setAccuracy(Criteria.ACCURACY_FINE); 
       c.setAltitudeRequired(false); 
       c.setBearingRequired(false); 
       c.setSpeedRequired(false); 


       // mLocationManager.requestSingleUpdate(c, mLocationListener, getMainLooper()); 

       mLocationManager.requestLocationUpdates(REFRESH_TIME, REFRESH_DISTANCE, c, mLocationListener, getMainLooper()); //Check if this can give us location updates on change in locations 


      } catch (Exception e) { 
       Log.d(TAG, " Exception e" + e.toString()); 
      } 
     }else{ 
      Log.d(TAG,"Location permission are disabled in service"); 
     } 



now using the Koperko solution 
int delay = 5000; // delay for 5 sec. 
int interval = 30000; // iterate every 30 sec. 
Timer timer = new Timer(); 

timer.scheduleAtFixedRate(new TimerTask() { 
     public void run() { 
      mFragment.getMapAsync(Context);       // The object of your own map support fragment 
     } 
    }, delay, interval); 



inYour onMapReady method 
use 
LatLng mLatLng=new LatLng(lat,lng); 
Marker marker = mGoogleMap.addMarker(new MarkerOptions().position(mLatLng));
