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
