POActivity is not responding while taking pictures more than one

Body
copied!<p>I got a problem. My activity will fail to respond when I take more than one picture. Sometimes taking even the first one has the ANR problem. I don't know why. I write the code according to DEV Guide. Here is my code:</p> <pre><code> 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; } } private void ICatchU(){ camera.takePicture(null, null, new PictureCallback() { @Override public void onPictureTaken(byte[] data, Camera camera) { camera.stopPreview(); Bitmap map =BitmapFactory.decodeByteArray(data, 0, data.length); String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date()); File picPath=new File(Environment.getExternalStorageDirectory().getAbsolutePath()+File.separator+"whycools"+File.separator+"picture"+File.separator+DateUtil.getFormattedDate(DateUtil.JUST_DATE)+File.separator+timeStamp+".jpg"); try { picPath.getParentFile().mkdirs(); picPath.createNewFile(); BufferedOutputStream bos=new BufferedOutputStream(new FileOutputStream(picPath)); map.compress(CompressFormat.JPEG, 80, bos); pdao.insertPic(new PictureInfo(picPath.getAbsolutePath(), timeStamp)); if(pictures==null){ pictures=new ArrayList<String>(); } System.out.println(picPath.getAbsolutePath()); pictures.add(picPath.getAbsolutePath()); bos.flush(); bos.close(); } catch (Exception e) { System.out.println(e.getLocalizedMessage());
