setMyLocationEnable에 대해 거부 될 수있는 호출 권한 android

Question

아아! 많은 노력과 검색 후에 나는 내 문제를 발견 할 수 없었다. Google지도에서 현재 위치를 찾고 싶지만 여전히 오류가 있습니다 (필요한 권한).

호출은 사용자에 의해 거부 될 수 있습니다 권한이 필요합니다 : 명시 적으로 해야 코드가 gMap.setMyLocationEnable(true);에서 처리를 명시 적으로 잠재적 인 '보안 예외'

을 권한을 사용할 수 있는지 확인 (체크 권한) 또는 아무도 내가 그것을 고칠 수있는 방법을 안내해 주시겠습니까? 내 코드는 아래와 같습니다.

난 그냥 몇 가지 권한을 추가하여 내 문제를 해결했다.

@Override 
    public void onMapReady(GoogleMap map) { 
     gMap = map; 
     gMap.setMapType(GoogleMap.MAP_TYPE_NORMAL); 
     gMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new 
       LatLng(0, 0), 0)); 

    //add this code... 
     if (gMap != null) { 
      gMap.addMarker(new MarkerOptions().position(new LatLng(0, 0)).title("Marker")); 
      if (ActivityCompat.checkSelfPermission(getActivity().getApplicationContext() 
        , Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(getActivity().getApplicationContext() 
        , Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) { 
       // TODO: Consider calling 
       // ActivityCompat#requestPermissions 
       // here to request the missing permissions, and then overriding 
       // public void onRequestPermissionsResult(int requestCode, String[] permissions, 
       //           int[] grantResults) 
       // to handle the case where the user grants the permission. See the documentation 
       // for ActivityCompat#requestPermissions for more details. 
       return; 
      } 
      gMap.setMyLocationEnabled(true); 
      gMap.getUiSettings().setMyLocationButtonEnabled(true); 


     } 
    }
