gpshandler를 사용하여 Looper.quit() 메서드를 수행하고 gps 객체의 get 메서드를 사용하여 위치를 가져옵니다.
이 방법은 정상적으로 작동하며 원하는 정보를 얻을 수 있습니다. 그러나, 가끔은 (시간의 절반은) 다음과 같은 경고 메시지를 얻을 :

는 이러한 경고는 과정에 영향을주지 않습니다하지만 난 무슨 일이 일어나고 있는지 이해하고 싶습니다. .. DDMS 사용하기 이러한 경고는 바인더 스레드에서 발생합니다. 왜 이런 일이 일어나고 왜 항상 그런 일이 일어나지 않는지 아는 사람이 있습니까? 감사합니다
편집
나는 조금 파고했고 나는 그들이 발생할 때, 그들은 바인더의 모든 발생할 수 있다는 것을 깨달았다하지만 그들은 한 번에 두 그들에 영향을 미친다. 나는 바인더에 익숙하지 않지만, 지위의 방송이있을 수 있습니까? 바인더가 연결된 스레드를 알 수있는 방법을 모르며 디버깅을 시도했지만 어떤 이유로 디버그 모드에서 경고를 재생할 수 없습니다. 그러나 onGpsStatusChanged 메소드에 디버그 로그를 설정하여 수신 된 gps 상태를보고합니다. 다음은 logcat의 출력입니다. 메시지를 어느 스레드에서 표시하는지 보여주기 위해 편집했습니다.
