您好我正在尝试保存在我的应用程序上拍摄的照片,但是当我尝试访问内存以放置数据时,会出现错误

无法解码流java.io.FileNotFoundException/storage/emulated/0 open failed:ENOENT(没有这样的文件或目录)

这是我的代码.

            Camera.PictureCallback mPictureCallback = new Camera.PictureCallback() {

        public void onPictureTaken(byte[] data, Camera camera) {
            // TODO Auto-generated method stub
            if (data != null){
                //Intent mIntent = new Intent();
                //mIntent.putExtra("image",imageData);

                mCamera.stopPreview();
                mPreviewRunning = false;
                mCamera.release();

                     Bitmap bitmap= BitmapFactory.decodeByteArray(data, 0, data.length,opts);
                     bitmap = Bitmap.createScaledBitmap(bitmap, 300, 300, false);
                     int width = bitmap.getWidth();
                     int height = bitmap.getHeight();
                     int newWidth = 300;
                     int newHeight = 300;

                     // calculate the scale - in this case = …

我正在尝试从我的数据库在线获取图片,在我的"imagelink"中,这是我表中的数据字段,我把那些我上传的图片的网址放在那里,但不幸的是它给了我这个错误.

这是我在onPostExecute中的代码:

 protected void onPostExecute(String file_url) {
        // dismiss the dialog after getting all products
        pDialog.dismiss();
        // updating UI from Background Thread
        runOnUiThread(new Runnable() {
            public void run() {
                /**
                 * Updating parsed JSON data into ListView
                 * */


                 ListAdapter adapter = new SimpleAdapter(
                        NewsActivity.this, productsList,
                        R.layout.news_list_item, new String[]{TAG_PID, TAG_IMAGELINK,
                        TAG_NEWSTITLE, TAG_DESCRIPTION},
                        new int[]{R.id.pid, R.id.imageView, R.id.newstitle, R.id.description});
                // updating listview
                setListAdapter(adapter);
            } …
