        Bitmap bitmap = null;
        InputStream in = null;
        try {
            URL url = new URL(imageURLStr);
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();

            in = conn.getInputStream();
            bitmap = BitmapFactory.decodeStream(in);
            in.close();
        } catch (SocketTimeoutException e) {
            bitmap = null;
            e.printStackTrace();
        } catch (IOException e) {
            bitmap = null;
            e.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
            bitmap = null;
        } catch (OutOfMemoryError e) {
            e.printStackTrace();
            bitmap = null;
        }
        return bitmap;

Use URL Encoder to encode the image URL, as you can see the URL have white spaces in the log report.

public static Bitmap downloadImage(String imageURLStr) {
      imageURLStr  = URLEncoder.encode(imageURLStr, "utf-8");
      //... rest of your code.
}

Edit: as you reported of issue '+' instead of %20

you can use

public static Bitmap downloadImage(String imageURLStr) {
          imageURLStr  = imageURLStr.replaceAll(" ", "%20");
          //... rest of your code.
}

you are right there are specs. I am trying to use your code but it replace the " " with "+". But it should be "%20". – Arslan Anwar Nov 04 '11 at 12:20

Thanks for you answer. I just try "Uri.encode()" by Nabeel answer. And its working. The above solution for replaceAll() is not look goods to me. – Arslan Anwar Nov 04 '11 at 12:35

I try to use URLEncoder.encode() to encode the URL. Its strange that it convert " " with "+".

Please try Uri.encode(imageURL). I just try it and its working perfectly.

I have tested that in android.

Looks like the file name is not being parsed correctly (the space between 'Manchester' and 'United').

Use URLEncoder.encode() to encode the URL.

Same issue. I am trying to use your code but it replace the " " with "+". But it should be "%20" – Arslan Anwar Nov 04 '11 at 12:20

Your second URL is very instable. It may return 404 in the most cases even in Chome. I have seen the picture only once.
