如何在前台服务中请求LocationUpdate方法

如何解决如何在前台服务中请求LocationUpdate方法

我的的士应用程序即使在后台/ 我试图通过前台通知 我成功地运行了具有通知的前台服务，但没有运行位置更新 这是服务

public class ExampleService extends Service {
    @Override
    public void onCreate() {
        super.onCreate();
    }
    @Override
    public int onStartCommand(Intent intent,int flags,int startId) {
        String input = intent.getStringExtra("inputExtra");
        Intent notificationIntent = new Intent(this,MainActivity.class);
        PendingIntent pendingIntent = PendingIntent.getActivity(this,notificationIntent,0);
        MainActivity.setCurrentLocation startLocationUpdate = new MainActivity.setCurrentLocation( );
        Notification notification = new NotificationCompat.Builder(this,CHANNEL_ID)

                .setContentTitle("Example Service")
                .setContentText(input)
                .setSmallIcon(R.drawable.ic_calendar)
                .setContentIntent(pendingIntent)
                .build();
        startForeground(1,notification);


        //do heavy work on a background thread
        //stopSelf();
        return START_NOT_STICKY;
    }



    @Override
    public void onDestroy() {
        super.onDestroy();
    }

    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }
}

这是MainActivity

/** Update driver location **/
    public static class setCurrentLocation extends AsyncTask<String,Void,String> {
        @Override
        protected String doInBackground(String... params) {
            String url = AppConst.Server_url+"set_position.PHP";
            final String latitude = params[0];
            final String longitude = params[1];
            StringRequest jsonObjReq = new StringRequest(Request.Method.POST,url,new Response.Listener<String>() {

                        @Override
                        public void onResponse(String response) {

                        }
                    },new Response.ErrorListener() {

                @Override
                public void onErrorResponse(VolleyError error) {

                }

            }) {

                @Override
                protected Map<String,String> getParams() {
                    Map<String,String> params = new HashMap<String,String>();
                    params.put("id_user",M.getID(context));
                    params.put("user_cat",M.getUserCategorie(context));
                    params.put("latitude",latitude);
                    params.put("longitude",longitude);
                    return params;
                }

            };
            AppController.getInstance().addToRequestQueue(jsonObjReq);
            jsonObjReq.setRetryPolicy(new DefaultRetryPolicy(
                    10000,DefaultRetryPolicy.DEFAULT_MAX_RETRIES,DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));

            return null;
        }

        @Override
        protected void onPostExecute(String result) {
            //to add spacing between cards
            if (this != null) {

            }

        }

        @Override
        protected void onPreExecute() {

        }
    }


    /** Start COOGLE API Client **/
    @Override
    public void onStart() {
        super.onStart();

        if (googleapiclient != null) {
            googleapiclient.connect();


        }
    }


    @Override
    public void onStop() {
        super.onStop();

        if (googleapiclient != null) {
            googleapiclient.disconnect();
        }
    }



    @Override
    public void onConnected(@Nullable Bundle bundle) {
        if (ActivityCompat.checkSelfPermission(context,Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED
                &&  ActivityCompat.checkSelfPermission(context,Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            return;
        }

        // Permissions ok,we get last location
        currentLocation = LocationServices.FusedLocationApi.getLastLocation(googleapiclient);
        startLocationUpdates();
    }



    private void startLocationUpdates() {



        if (ActivityCompat.checkSelfPermission(context,Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
//            Toast.makeText(this,"You need to enable permissions to display location !",Toast.LENGTH_SHORT).show();
        }


        LocationServices.FusedLocationApi.requestLocationUpdates(googleapiclient,locationRequest,this);

    }


    @Override
    public void onConnectionSuspended(int i) {
    }

    @Override
    public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
    }

plz给出了执行此操作的确切代码，因为我通过mysefl尝试了一些代码，但对我没有任何帮助
