Retrieving Bitmap from URL

Question

Though not very elegant, I used a quick hack to get around this with web views. However, I still hope to discover what was wrong.

With respect to the flickr API,

I have an image that I want a Bitmap object for and I have access to the user id grimneko and picture id 8638235984.

Therefore, I tried

URL url = new URL("http://www.flickr.com/photos/grimneko/8637130199/lightbox/");
Bitmap mp = BitmapFactory.decodeStream(url.openConnection().getInputStream());

However, mp is null in this case. I also tried www.google.com as the url and that also does not appear to work.

However, http://3.bp.blogspot.com/-sUAEV-EIlyY/T4WIGDkoLpI/AAAAAAAACKI/epNLfw01cW0/s320/corgi+working.jpg does work.

My guess is that Bitmap objects can only be created from urls that have image extensions. Is this correct?

If that is the case, how might I render the image from that flickr url in a Image View?

Try this..

   public static Bitmap getBitmapFromURL() {
        try {
            URL url = new URL("http://www.flickr.com/photos/grimneko/8637130199/lightbox/");
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setDoInput(true);
            connection.connect();
            InputStream input = connection.getInputStream();
            Bitmap myBitmap = BitmapFactory.decodeStream(input);
            return myBitmap;
        } catch (IOException e) {
            e.printStackTrace();
            return null;
        }
}

Hi Tamilan, thank you for the response. However, if you look at the code above it is almost identical. Upon testing this, it still returns null. – user1431282 Oct 06 '13 at 06:32
@user1431282 have you check with this link http://3.bp.blogspot.com/-sUAEV-EIlyY/T4WIGDkoLpI/AAAAAAAACKI/epNLfw01cW0/s320/corgi+working.jpg did you get image – Hariharan Oct 06 '13 at 06:36
Yes :) its does work with that image as I mentioned in my original post. I was wondering more about why this approach does not work with any of the flickr images. – user1431282 Oct 06 '13 at 22:21
@user1431282 because that's not single image that's gallery that's why it's not woking.. – Hariharan Oct 07 '13 at 03:58
@user1431282 here is that same image link http://farm9.staticflickr.com/8246/8637130199_0b39510452_o.jpg try with this link – Hariharan Oct 07 '13 at 04:11
