runtime error, but debugging step by step works fine

I wrote an android program to take a picture without preview. My programs works fine when I debug it step by step. However, when I run it in execution mode, the program doesn't work as expected. No picture is saved and the program can not finish. In addition, I can not use my camera in other android applications(e.g. Camera, Camcorder) unless I restart my phone. Anybody have any ideas about this problem? The code for taking pictures and the logged errors is as follows:

Code for taking pictures:

    SurfaceView view = new SurfaceView(this);
    mCamera = Camera.open();
    Camera.Parameters p = mCamera.getParameters();
    p.setPictureFormat(PixelFormat.JPEG);
    mCamera.setParameters(p);

    try {
        mCamera.setPreviewDisplay(view.getHolder());
        mCamera.startPreview();
        mCamera.takePicture(null, null, mPictureCallback);
        mCamera.stopPreview();
        mCamera.unlock();
        mCamera.release();
    } catch (Exception e) {
        mCamera.stopPreview();
        mCamera.release();
        e.printStackTrace();            
    }

The callback function

Camera.PictureCallback mPictureCallback = new Camera.PictureCallback() {
          public void onPictureTaken(byte[] imageData, Camera c) {
               if (imageData != null) {
            StoreByteImage(mContext, imageData, 50,
                    "ImageName");
            finish();
        }
    }
};
}

The reported errors by logcat:

ERROR/Adreno200-ES20(130): rb verson is SBA #24

Can anybody give any suggestion? Thank you in advance

does this work for you?

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            File file = new File(Environment.getExternalStorageDirectory(),
                    currentTimeString + ".jpg");
            outputFileUri = Uri.fromFile(file);
            intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
            startActivityForResult(intent, TAKE_PICTURE);
