Активность не отвечает при съемке более одного

/ 15 декабря 2011

У меня проблема. Моя деятельность не будет отвечать, если я сделаю несколько снимков. Иногда даже при первом приеме возникает проблема ANR. Я не знаю почему. Я пишу код в соответствии с DEV Guide. Вот мой код: 

    public class CameraActivity extends Activity implements SurfaceHolder.Callback,OnClickListener,AutoFocusCallback{

    private Button takeShot,goBack;
    private SurfaceView surfaceView;
    private SurfaceHolder holder;
    private Camera camera;

    private ArrayList<String> pictures;

    private PictureDAO pdao;
    public static final int PICTURE_OK=1554;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.camera);
        pdao=new PictureDAO(this);
        initComponent();
    }

    private void initComponent(){
        surfaceView=(SurfaceView)findViewById(R.id.cameraView);
        holder=surfaceView.getHolder();
        holder.addCallback(this);
        holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
        takeShot=(Button)findViewById(R.id.lets_take_it);
        goBack=(Button)findViewById(R.id.back_to_tab3_button);
        takeShot.setOnClickListener(this);
        goBack.setOnClickListener(this);
    }
    /**
     * set camera parameters
     */
    private void setCameraParameters(){
        Parameters para=camera.getParameters();
        para.setPictureFormat(ImageFormat.JPEG);
        Size preSize=para.getSupportedPreviewSizes().get(para.getSupportedPreviewSizes().size()-1);

        para.setPreviewSize(preSize.width, preSize.height);
        Size picSize=para.getSupportedPictureSizes().get(0);
        para.setPictureSize(picSize.width, picSize.height);

        camera.setParameters(para);
        camera.setDisplayOrientation(90);
    }
    @Override
    public void surfaceCreated(SurfaceHolder holder) {
        camera=Camera.open();
        setCameraParameters();
        try {
            camera.setPreviewDisplay(holder);
        } catch (Exception e) {
            LogUtil.log(e.getMessage());
            LogUtil.log(e.getLocalizedMessage());
            e.printStackTrace();
        }
        camera.startPreview();
        camera.autoFocus(this);
    }

    @Override
    public void surfaceChanged(SurfaceHolder holder, int format, int width,
            int height) {

    }

    @Override
    public void surfaceDestroyed(SurfaceHolder holder) {
        releaseCamera();
    }

    private void releaseCamera(){
        if(camera!=null){
            camera.stopPreview();
            camera.release();
            camera=null;
        }
    }

                    pdao.insertPic(new PictureInfo(picPath.getAbsolutePath(), timeStamp));
                    if(pictures==null){

Заправьте onClick() во избежание блокировки UI.
