AndroidのGoogleマップがMarshmallowで動作していません

Question

私はアプリケーションがLollipopバージョンで正常に動作するまでユーザーの現在地を取得できるアプリケーションで作業していますが、marshmallowでテストしているときにユーザーの場所を取得できません。

MainActivity.class

public class MapsActivity extends FragmentActivity implements 
     OnMapReadyCallback, 
     GoogleApiClient.ConnectionCallbacks, 
     GoogleApiClient.OnConnectionFailedListener, 
     GoogleMap.OnMarkerDragListener,

     View.OnClickListener{ 

    //Our Map 
    private GoogleMap mMap; 

    //To store longitude and latitude from map 
    private double longitude; 
    private double latitude; 

    //Buttons 
    private ImageButton buttonSave; 
    private ImageButton buttonCurrent;

     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()

はあなたのMainActivityにこのコードを追加するか、HomeActivity

private void fn_permission() { 
    if ((ContextCompat.checkSelfPermission(getApplicationContext(), 
      Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED)) { 
(ActivityCompat.shouldShowRequestPermissionRationale(MainActivity.this, 
       Manifest.permission.READ_EXTERNAL_STORAGE)) && (ActivityCompat.shouldShowRequestPermissionRationale(MainActivity.this, 
       Manifest.permission.ACCESS_FINE_LOCATION))) { 

     } else { 
      ActivityCompat.requestPermissions(MainActivity.this, new String[]{ Manifest.permission.ACCESS_FINE_LOCATION 
        }, 
        REQUEST_PERMISSIONS); 

     } 
    }else { 

    } 
}
