Как получить долготу и широту в Marshmallow Android 6.0 [duplicate]

С помощью ответа CommonsWare и Blackkara я смог решить свою проблему.

В соответствии с их предложением я изменил свой код и посмотрел каждый шаг моего кода с отладкой .

Из-за этого я пришел с проблемой, что мой onLocationChanged () не был уволен в случае с Marshmallow, но на удивление, он загорелся в случае более старых устройств, которые меньше, чем Android M или 6.0 .

Для решения этого я изменил свой код, как показано ниже, здесь я размещаю полный код, чтобы любой, у кого есть такая же проблема, мог избавиться от него.

GPSTracker.java

public class GPSTracker extends Service{

    private  Context mContext;

    // Flag for GPS status
    boolean isGPSEnabled = false;

    // Flag for network status
    boolean isNetworkEnabled = false;

    // Flag for GPS status
    boolean canGetLocation = false;

    Location location; // Location
    double latitude; // Latitude
    double longitude; // Longitude

    // The minimum distance to change Updates in meters
    private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 1000; // 10 meters

    // The minimum time between updates in milliseconds
    private static final long MIN_TIME_BW_UPDATES = 1000 * 60 * 1; // 1 minute

    // Declaring a Location Manager
    protected LocationManager locationManager;

    Activity activity;

    public GPSTracker() {
    }

    public GPSTracker(Context context, Activity activity) {
        this.mContext = context;
        this.activity = activity;
        getLocation();
    }

            // Getting GPS status
            isGPSEnabled = locationManager
                    .isProviderEnabled(LocationManager.GPS_PROVIDER);
