Не получить широту и долготу в Android Marshmallow API 23

Question

Я страдаю от проблемы получения значения 0.0 по широте и долготе в Android Marshmallow API 23. и другие API работают отлично. Проблема заключается в карте Google, которая не получает текущее местоположение.

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) { 
        // no network provider is enabled 
       } else { 
        this.canGetLocation = true; 
        // First get location from Network Provider 
        if (isNetworkEnabled) { 
         locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER,MIN_TIME_BW_UPDATES,MIN_DISTANCE_CHANGE_FOR_UPDATES, this); 
         Log.d("Network", "Network"); 
         if (locationManager != null) { 
          location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER); 
          if (location != null) { 
           latitude = location.getLatitude(); 
           longitude = location.getLongitude(); 
          } 
         } 
        } 
        // if GPS Enabled get lat/long using GPS Services 
        if (isGPSEnabled) { 
         if (location == null) { 
          locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,MIN_TIME_BW_UPDATES,MIN_DISTANCE_CHANGE_FOR_UPDATES, this);

Android Manifest.xml

<uses-permission-sdk-23 android:name="android.permission.ACCESS_COARSE_LOCATION"/> 
<uses-permission-sdk-23 android:name="android.permission.ACCESS_FINE_LOCATION"/> 

Answer 1

Вы должны реализовать разрешение во время выполнения в зефира Here, и если вы не выполняют этого, чем вы должны вручную включить разрешение настройки

Проверьте ключ API в AndroidManifest.xml, который вы получаете из учетной записи консоли Google

<meta-data 
     android:name="com.google.android.maps.v2.API_KEY" 
     android:value="YOUR_KEY" />

Implement run time permission for mashmallow 
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { 
     checkLocationPermission(); 
    } else { 
     Log.d("onCreate", "Google Play Services available."); 
    } 
public boolean checkLocationPermission() { 
     if (ContextCompat.checkSelfPermission(getActivity(), 
       Manifest.permission.ACCESS_FINE_LOCATION) 
       != PackageManager.PERMISSION_GRANTED) { 

      // Asking user if explanation is needed 
      if (ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), 
        Manifest.permission.ACCESS_FINE_LOCATION)) { 

       // Show an explanation to the user *asynchronously* -- don't block 
       // this thread waiting for the user's response! After the user 
       // sees the explanation, try again to request the permission. 

       //Prompt the user once explanation has been shown 
       new AlertDialog.Builder(getActivity()) 
         .setTitle("Permission needed") 
         .setMessage("Please allow permission to access your location to continue service") 
         .setPositiveButton("OK", new DialogInterface.OnClickListener() { 
          @Override 
          public void onClick(DialogInterface dialogInterface, int i) { 
           //Prompt the user once explanation has been shown 
           ActivityCompat.requestPermissions(getActivity(), 
             new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 
             MY_PERMISSIONS_REQUEST_LOCATION); 
          } 
         }) 
         .create() 
         .show(); 

      } else { 
       // No explanation needed, we can request the permission. 
       ActivityCompat.requestPermissions(getActivity(), 
         new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 
         MY_PERMISSIONS_REQUEST_LOCATION); 
      } 
      return false; 
     } else { 
      return true; 
     } 
    }
