Android MediaServer远程活页夹相机对象已死亡-仅在KITKAT上

我正在使用SurfaceView并使用源代码，但每当我拍摄背对背的图像时，都会得到：

mediaserver's remote binder Camera object died
Camera service died!
Camera Error 100

我的设备支持Android Kitkat，所以我可以确切地知道我在做什么——我缺少什么。我为什么会遇到这个问题？

不确定，但是

setPreviewDisplay（SurfaceHolder.getSurface（））

将适用于you@Amy在我必须在课堂上尝试的地方，我已经在使用mCamera.setPreviewDisplay（mHolder）@索纳利：你有没有找到解决办法或这种行为的原因？
