나는 하나의 7 인치와 10 인치 .. 두 개의 은하 정제에 대한 사용자 정의 카메라 응용 프로그램과 테스트를 개발하고 있습니다. 10 인치는 위대한하지만 7inch에서 작동, 내가 걸릴 때 사진을 찍으면 카메라 미리보기가 멈추고 logCat은 CAMERA SNAP에서 멈 춥니 다. 내 customcamera 클래스에서 오류없이 클릭하면 내 btn_snap_pic에 로그인했습니다. 응용 프로그램이 그냥 중단됩니다 .. 그리고 만약 내가 그것을 다시 열고 응용 프로그램을 다시 열면 "카메라에 연결 실패"나는 내 응용 프로그램이 얼어 붙어 버렸을 때 나는이 오류가 있다고 가정합니다 카메라, 발표 없었어 .. 어쨌든, 아래에있는 내 내 CustomCamera 클래스 모두 내 CamLayer 내 미리보기입니다 ..사진은 갤럭시 7 인치 탭하지만 10inch 촬영하지 후 동결
