onLocationChanged가 잘못된 위치 (바 렌츠 해)를 가리키고 있습니까?

아주 기본적인 응용 프로그램은 새로운 좌표로 카메라를 이동합니다.

onLocationChanged은 위치가 변경 될 때마다 호출됩니다. 그것은 새로운 좌표로 카메라를 이동해야하지만, 대신에 Barents 바다의 어딘가를 가리 키기 시작합니다. 나는 5 번 이상 전체 문서를 던지지 만 여전히 그것을 얻지 못했습니다. 응용 프로그램에

Answer 1

좌표 75.8467264/30.862686 및 75.8467229/30.862678은 바 렌츠 해에 있습니다.

변경

LatLng latLng = new LatLng(location.getLongitude(), location.getLatitude()); 

onLocationChanged()에서

LatLng latLng = new LatLng(location.getLatitude, location.getLongitude()()); 

에지도에 인도 북부를 볼 수 있습니다.
