我暂停相机应用后手机崩溃，然后切换回来拍照。 这只发生在我的三星Galaxy S上，在我的Huwai设备上它完全有效。 我找到了导致错误的代码行。不幸的是，这些线条非常有用，所以我不能剥离它们：
public void surfaceDestroyed(SurfaceHolder holder) { // <14>
Log.d(TAG,"surfaceDestroyed()");
if(this.camera != null){
camera.stopPreview();
// the next two lines lead to the error after switching back to the app and taking a picure
camera.release();
this.camera = null;
}
}
不幸的是我没有得到堆栈跟踪。我得到的只是：

有人知道如何解决这个问题吗？
答案 0 :(得分：21)
我终于（经过几个小时，几乎几天的调试）通过删除预览视图并重新实例化来解决这个问题：
@Override
protected void onResume() {
super.onResume();
mSurfaceViewContainer.removeAllViews();
mSurfaceView = new SurfaceView(mSurfaceViewContainer.getContext());
mSurfaceViewContainer.addView(mSurfaceView, new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
SurfaceHolder previewHolder = mSurfaceView.getHolder();
previewHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
previewHolder.addCallback(mSurfaceHolderCallback);
}
答案 1 :(得分：13)
抛出了一个IOException（Could not find method java.io.IOException.<init>），但是IOException构造函数使用了was introduced in API level 9，因此它在Galaxy S上不存在，而是显示一个奇怪的日志。
关于您的问题，我建议您在lock()之前致电release()：
camera.stopPreview();
camera.lock();
camera.release();
this.camera = null;
我不知道这是否有效，但在this source code中，我发现了一条评论说：
// If we don't lock the camera, release() will fail.
camera.lock();
camera.release();
这似乎显然是相关的。
