Not Load Images from Web in my application

Hello i use Loading Images for Loading Images. But my images are not load. I work on that and develop one Demo program that is as follows.

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    new DownloadImageTask((ImageView) findViewById(R.id.my_image))
            .execute("http://www.morroccomethod.com/components/com_virtuemart/shop_image/category/resized/Raw_Conditioner_500835f701532_175x175.jpg");
}

private class DownloadImageTask extends AsyncTask<String, Void, Bitmap> {
    ImageView bmImage;

    @Override
    protected void onPreExecute() {
        // TODO Auto-generated method stub
        super.onPreExecute();
        pd = new ProgressDialog(ImageLoadExampleActivity.this);
        pd.show();
    }

    public DownloadImageTask(ImageView bmImage) {
        this.bmImage = bmImage;
    }

    protected Bitmap doInBackground(String... urls) {
        String urldisplay = urls[0];
        Bitmap mIcon11 = null;
        try {
            InputStream in = new java.net.URL(urldisplay).openStream();
            mIcon11 = BitmapFactory.decodeStream(in);
        } catch (Exception e) {
            Log.e("Error", e.getMessage());
            e.printStackTrace();
        }
        return mIcon11;
    }

    protected void onPostExecute(Bitmap result) {
        bmImage.setImageBitmap(result);
        pd.dismiss();

    }
}

It does not work. But if i change URL of image at that time image is loaded successfully. My question is this perticular url is not loaded in my android application. Please help me to find this. I spend one days on this. Thanks in advance.

public String loadImageFromWebOperations(String url, String path) {
    try {
        is = (InputStream) new URL(url).getContent();
        System.out.println(path);
        File f = new File(path);
        f.createNewFile();
        FileOutputStream fos = new FileOutputStream(f);
        try {
            byte[] b = new byte[100];
            int l = 0;
            while ((l = is.read(b)) != -1)
            fos.write(b, 0, l);
        } catch (Exception e) {
            Log.e("Error in creating file", "", e);
        }
        Log.e("created file path is :", "" + f.getAbsolutePath());
        return f.getAbsolutePath();
    } catch (Exception e) {
        System.out.println("Exc=" + e);
        return null;
    }
}

If any issue let me know...

I use the following to get images from an endpoint

URL url = new URL(imageUrl);
InputStream content = (InputStream)url.getContent();
Drawable image = Drawable.createFromStream(content , "src");

perhaps you can adapt this

Okay I downloaded the sample and looked at URLs - the issue appears to be the HTTP => HTTPS redirection (I mentioned that I had to change them in my sample - I also notice my browser was forced to switch to https when I tried to load your images from the supplied strings). The sample does not appear to handle that correctly however if I alter ImageLoader.getBitmap to this then it does

private Bitmap getBitmap(String url) 
{
    File f=fileCache.getFile(url);

    //from SD cache
    Bitmap b = decodeFile(f);
    if(b!=null)
        return b;

    //from web
    try {
        Bitmap bitmap=null;

        HttpURLConnection conn;
        URL imageUrl = new URL(url);
        int rc = -1;
        do {
            conn = (HttpURLConnection)imageUrl.openConnection();
            conn.setConnectTimeout(30000);
            conn.setReadTimeout(30000);
            conn.setInstanceFollowRedirects(true);
            rc = conn.getResponseCode();
            imageUrl = conn.getURL();
        } while (rc == -1); // hmmm - perhaps a http => https

        InputStream is=conn.getInputStream();
        OutputStream os = new FileOutputStream(f);
        Utils.CopyStream(is, os);
        os.close();
        bitmap = decodeFile(f);
        return bitmap;
    } catch (Exception ex){
       ex.printStackTrace();
       return null;
    }
}
