현재 위치는 안드로이드에서 null이됩니다

Question

화면에 들어가면 GPS가 켜져 있는지 확인하고 그렇지 않으면 GPS를 활성화하는 대화 상자가 표시됩니다. 사용자가 예를 클릭하면 onActivityResult -> GPS가 켜지고 위치를 얻으려고 시도하지만 null이 항상 반환됩니다.

GPS가있는 화면으로 들어가면 위치가 올바르게 검색됩니다. 나는 며칠 동안이 일에 어려움을 겪었으므로 자원을 찾을 수없는 것 같습니다.

제가 뭘 잘못했는지 도와주세요. u는 LOG를 받고 있지 않은 경우

이 변화를 시도하고 LOG는 u는 어떻게해야합니까 무엇을 게시, 당신은 필요한 권한이 해달라고 유 얻는 경우에 위치를 기록하지만 의미, 그렇다면 우리는 허가 문제를 배제 할 수 있습니다. 그러나 API 레벨이 테스트중인 방식은 무엇입니까?
