I want to find current location on connected. I am currently using FusedLocationApi which is deprecated. i have to use requestLocationUpdate method but i am getting some syntax error while using FusedLocationProviderClient. i also have to use removeLocationupdate in onPause and onDestroy.

This is my current code which is using FusedLocationProviderClient-

@Override
public void onConnected(@Nullable Bundle bundle) 
 mLocationRequest = LocationRequest.create();
 mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
 mLocationRequest.setInterval(1000);
 mLocationRequest.setFastestInterval(1000);

 if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, 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;
 
 LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleClientApi, mLocationRequest, this);
 if (mCurrentLocMarker == null) 
 Location loc = LocationServices.FusedLocationApi.getLastLocation(mGoogleClientApi);
 mLastLocation = loc;
 if (loc != null) 
 LatLng latLng = new LatLng(loc.getLatitude(), loc.getLongitude());
 MarkerOptions markerOptions = new MarkerOptions();
 markerOptions.position(latLng);
 markerOptions.title("Current Location");
 markerOptions.flat(true);
 int height = 150;
 int width = 150;
 BitmapDrawable bitmapDrawable = (BitmapDrawable)getResources().getDrawable(R.drawable.icon_navigation);
 Bitmap bitmap = bitmapDrawable.getBitmap();
 Bitmap marker = Bitmap.createScaledBitmap(bitmap, width, height, false);
 markerOptions.icon(BitmapDescriptorFactory.fromBitmap(marker));
 markerOptions.anchor(0.5f, 0.5f);
 mCurrentLocMarker = mMap.addMarker(markerOptions);
 CameraPosition cameraPosition = new CameraPosition.Builder()
 .target(latLng)
 .zoom(17)
 .build();
 mMap.moveCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));
 

 

@Override
protected void onPause() 
 super.onPause();
 mapView.onPause();
 String trackid = SharedPreferenceManager.getmInstance(this).getTrackId();
 if (mGoogleClientApi != null) 
 LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleClientApi,this);
 
 if (!trackid.equals("NO DATA")) 
 startService(new Intent(this, LocationService.class));
 


@Override
protected void onDestroy() 
 super.onDestroy();
 mapView.onDestroy();
 String trackid = SharedPreferenceManager.getmInstance(this).getTrackId();
 if (mGoogleClientApi != null) 
 LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleClientApi, this);
 
 if (!trackid.equals("NO DATA")) 
 startService(new Intent(this, LocationService.class));
 

This is i tried but cannot implement its requestLocationUpdate and removeLocationUpdate:

FusedLocationProviderClient fusedLocationProviderClient; //Global variable
fusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(this); //initiate in onCreate

Your start is like you need.

FusedLocationProviderClient fusedLocationProviderClient; //Global variable
fusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(this); //initiate in onCreate

For getting location from another app as googlemaps you can use mFusedLocationClient.getLastLocation() it have listeners, addOnSuccessListener gives to you location, addOnCompleteListener and task.getResult() == null means that you need to do your own request like mFusedLocationClient.requestLocationUpdates(getLocationRequest(), mLocationCallback, null);

and you need to remove your listener for example in onPause like mFusedLocationClient.removeLocationUpdates(mLocationCallback)

you can look this examples https://github.com/googlesamples/android-play-location
