[java] Android ‘gps에는 ACCESS_FINE_LOCATION이 필요합니다’오류가 발생하지만 매니페스트 파일에 다음이 포함되어 있습니다.

ACCESS_COARSE_LOCATION, ACCESS_FINE_LOCATION및 WRITE_EXTERNAL_STORAGE모두 Android 6.0 런타임 권한 시스템의 일부입니다 . 당신이로 매니페스트에 그들을 가지고 이외에, 당신은 또한 (사용하여 런타임에 사용자로부터 그들을 요청해야 requestPermissions()합니다 (사용하여이있는 경우) 및 참조 checkSelfPermission()).

단기간에 한 가지 해결 방법은 targetSdkVersion23 미만 으로 낮추는 것 입니다.

그러나 결국에는 런타임 권한 시스템을 사용하도록 앱을 업데이트해야합니다.

예를 들어이 활동은 5 개의 권한으로 작동합니다. 4 개는 런타임 권한이지만 현재는 3 개만 처리하고 있습니다 (이전 WRITE_EXTERNAL_STORAGE에 런타임 권한 목록에 추가 되었음).

requestPermissions () 함수의 경우 매개 변수가 “ACCESS_COARSE_LOCATION”이어야합니까? 아니면 “android.permission.ACCESS_COARSE_LOCATION”전체 이름을 포함해야합니까?

Manifest.permission위에 표시된 대로에 정의 된 상수를 사용합니다 .

또한 요청 코드는 무엇입니까?

이는에 대한 첫 번째 매개 변수로 다시 전달 onRequestPermissionsResult()되므로 한 requestPermissions()호출을 다른 호출에 알릴 수 있습니다 .
