Android с плавным ходом с использованием API Google

Question

Я - разработчик Android для начинающих. Я использую Android Studio для создания приложения, которое дает точное местоположение и постоянно обновляет его каждый раз. Я использовал GPS и поставщика сети, создав класс GPStracker, который дает мне широту и долготу. А затем отобразите эти координаты на фрагменте карты.

Проблема в том, что я снова получаю одно и то же место снова и снова, чтобы соответствовать долготе и широте, равным нулю. Я знаю, что есть много вопросов о местоположении Android, но я не могу найти помощь там.

Это где я обновить мою карту

private void updateMap() { 
    mMap.clear(); 
    double latitude = gps.getLatitude(); 
    double longitude = gps.getLongitude(); 

    // Create a LatLng object for the current location 
    LatLng latLng = new LatLng(latitude, longitude); 
    // Show the current location in Google Map 
    mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng)); 
    // Zoom in the Google Map 
    mMap.animateCamera(CameraUpdateFactory.zoomTo(1)); 
    mMap.addMarker(new MarkerOptions().position(new LatLng(latitude, longitude)).title("You are here!").snippet("Estimated location!")); 
    //camera settings 
    CameraUpdate yourLocation = CameraUpdateFactory.newLatLngZoom(latLng, 1); 
    mMap.animateCamera(yourLocation); 
    CameraPosition cameraPosition = new CameraPosition.Builder() 
      .target(latLng)  // Sets the center of the map to LatLng (refer to previous snippet) 
      .zoom(1)     // Sets the zoom 
      .bearing(90)    // Sets the orientation of the camera to east 
      .tilt(30)     // Sets the tilt of the camera to 30 degrees 
      .build();     // Creates a CameraPosition from the builder 
    mMap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition)); 
} 

И это мой GPStracker класс

public abstract class GPSTracker extends Service implements LocationListener { 
private final 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 
double speed, direction; 
// The minimum distance to change Updates in meters 
private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 10; // 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; 

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

public Location getLocation() { 
    try { 
     locationManager = (LocationManager) mContext 
       .getSystemService(LOCATION_SERVICE); 
     // getting GPS status 
     isGPSEnabled = locationManager 
       .isProviderEnabled(LocationManager.GPS_PROVIDER); 
     // getting network status 
     isNetworkEnabled = locationManager 
       .isProviderEnabled(LocationManager.NETWORK_PROVIDER); 
     if (!isGPSEnabled && !isNetworkEnabled) { 
      Toast.makeText(this, "no network provider is enabled)", 
        Toast.LENGTH_LONG).show(); 
      showSettingsAlert(); 
      // no network provider is enabled 
     } else {

Попробуйте использовать Android эмулятор или genymotion эмулятор. У них отличная функция для ввода мест в эмулятор.

Эта ссылка поможет вам включить genymotion в GPS
