Java 位置管理器在android 4.4.4中不工作

Android业余爱好者和第一次发布在这里。 我正在开发一个应用程序，获取用户的GPS位置，然后发送到Mysql数据库。在安卓7.1（三星note 5）上，它工作得很好，但当我尝试在安卓4.2.2（三星J1）上使用时，位置不会更新

在my MapsActivity.java下面

public class MapsActivity extends AppCompatActivity implements OnMapReadyCallback {

    private GoogleMap mMap;
    LocationManager locationManager;
    LocationListener locationListener;

    final int INTERVAL = 0; /* milliseconds */
    final int DISTANCE = 0; /* meters */

    //after asking the user for permission
    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);

        // to check if the request code is the same as we used, in this case 1
        if (requestCode == 1) {
            //if true, then it means we have the permission
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
                    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, INTERVAL, DISTANCE, locationListener); //every 15 seconds or 50 meters
                }
            }
        }
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);
        // Obtain the SupportMapFragment and get notified when the map is ready to be used.
        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);

    }

    /**
     * Manipulates the map once available.
     * This callback is triggered when the map is ready to be used.
     * This is where we can add markers or lines, add listeners or move the camera. In this case,
