Android 导致碰撞的方向错误

我有一个活动，该活动将方向设置为lanscape，该活动运行正常，但如果启动活动时手机处于纵向模式，我会收到此错误，活动停止并返回到其他活动：

05-30 11:06:48.335: D/DOMX(125): ERROR: failed check:(eError == OMX_ErrorNone) || (eError == OMX_ErrorNoMore) - returning error: 0x80001005 - Error returned from OMX API in ducati
05-30 11:06:48.335: E/CameraHAL(125): Error while configuring rotation 0x80001005

05-30 11:06:48.765: E/CameraHAL(125): Adapter state switch PREVIEW_ACTIVE Invalid Op! event = 0xf

正在从另一个也设置为横向的活动调用该活动，如果在横向中保持设备时切换活动，则不会崩溃。。仅在启动时以纵向方式握住设备时

在这两个活动中，我在onCreate（）中设置方向，如下所示：

这似乎与我在即将启动的活动中放置CameraPreview曲面有关，因此我将包括camera类，以防出现问题：

public class KNCamLayer extends SurfaceView {
        Camera camera;
        SurfaceHolder previewHolder;

        public KNCamLayer(Context context)
        {
            super(context);
            previewHolder = this.getHolder();

            //previewHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
            previewHolder.addCallback(surfaceHolderListener);

        }

        SurfaceHolder.Callback surfaceHolderListener = new SurfaceHolder.Callback() {

            public void surfaceCreated(SurfaceHolder holder) {
                camera=Camera.open();
            try {
                camera.setPreviewDisplay(previewHolder);

            }
                catch (Throwable e){ }
            }
            public void surfaceChanged(SurfaceHolder holder, int format, int width, int height)
            {
                Parameters params = camera.getParameters();
                //params.setPreviewSize(width, height);
                params.setPictureFormat(PixelFormat.JPEG);
                camera.setParameters(params);
                camera.startPreview();


            }
            public void surfaceDestroyed(SurfaceHolder arg0)
            {
                camera.stopPreview();
                camera.release();
            }

        };

        public void onResume() {
            camera.startPreview();

        }

        public void onPause() {
            // TODO Auto-generated method stub
            camera.stopPreview();
        }

}

CameraView添加到活动的onResume（）中，如下所示：

好吧，看来如果我在清单中为那个活动设置方向。。问题消失了。。但我不明白确切的原因。
修正：

---

android:screenOrientation=“landscape”

在活动清单中

因为此属性强制您的相机活动处于横向，所以当未定义方向时，选项设备本身无法决定要执行哪个视图

public class KNCamLayer extends SurfaceView {
        Camera camera;
        SurfaceHolder previewHolder;

        public KNCamLayer(Context context)
        {
            super(context);
            previewHolder = this.getHolder();

            //previewHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
            previewHolder.addCallback(surfaceHolderListener);

        }

        SurfaceHolder.Callback surfaceHolderListener = new SurfaceHolder.Callback() {

            public void surfaceCreated(SurfaceHolder holder) {
                camera=Camera.open();
            try {
                camera.setPreviewDisplay(previewHolder);

            }
                catch (Throwable e){ }
            }
            public void surfaceChanged(SurfaceHolder holder, int format, int width, int height)
            {
                Parameters params = camera.getParameters();
                //params.setPreviewSize(width, height);
                params.setPictureFormat(PixelFormat.JPEG);
                camera.setParameters(params);
                camera.startPreview();


            }
            public void surfaceDestroyed(SurfaceHolder arg0)
            {
                camera.stopPreview();
                camera.release();
            }

        };

        public void onResume() {
            camera.startPreview();

        }

        public void onPause() {
            // TODO Auto-generated method stub
            camera.stopPreview();
        }

}

camPreview = new KNCamLayer(this);
        frame.addView(camPreview, new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
