图像不在SD卡上

有什么想法为什么?另外,当我在“活动”中以位图形式查看图像时(重新启动后),图片会以错误的方式翻转。有什么想法吗?

我的代码如下:

Camera.PictureCallback photoCallback = new Camera.PictureCallback() {
  public void onPictureTaken(byte[] data, Camera camera) {
    // TODO Auto-generated method stub
    FileOutputStream fos;
    try
    {
      Bitmap bm = BitmapFactory.decodeByteArray(data, 0, data.length);
      fileUrl = MediaStore.Images.Media.insertImage(getContentResolver(), bm, "LastTaken", "Picture");

      if(fileUrl == null)
      {
        Log.d("Still", "Image Insert Failed");
        return;
      }
      else
      {
        picUri = Uri.parse(fileUrl);
        sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, picUri));
      }
    }
    catch(Exception e)
    {
      Log.d("Picture", "Error Picture: ", e);
    }
    camera.startPreview();
  }
};
