How to get progress (percent) when downloading image from url .
I think i should customize code at HttpUrlDownloader.java

Here it's what i'm going so far ::

                while (true) {
                    final URL u = new URL(thisUrl);
                    urlConnection = (HttpURLConnection) u.openConnection();
                    urlConnection.setInstanceFollowRedirects(true);

                    if (mRequestPropertiesCallback != null) {
                        final ArrayList<NameValuePair> props = mRequestPropertiesCallback.getHeadersForRequest(context, url);
                        if (props != null) {
                            for (final NameValuePair pair : props) {
                                urlConnection.addRequestProperty(pair.getName(), pair.getValue());
                            }
                        }
                    }

                    if (urlConnection.getResponseCode() != HttpURLConnection.HTTP_MOVED_TEMP
                            && urlConnection.getResponseCode() != HttpURLConnection.HTTP_MOVED_PERM)
                        break;
                    thisUrl = urlConnection.getHeaderField("Location");
                }

                if (urlConnection.getResponseCode() != HttpURLConnection.HTTP_OK) {
                    UrlImageViewHelper.clog("Response Code: " + urlConnection.getResponseCode());
                    return null;
                }
                is = urlConnection.getInputStream();

                //customize
                int fileLength = urlConnection.getContentLength();
                byte data[] = new byte[1024];
                long total = 0;
                int count;
                while ((count = is.read(data)) != -1) {
                    total += count;
                    publishProgress((int) (total * 100 / fileLength));
                }
                callback.onDownloadComplete(HttpUrlDownloader.this, is, null);
                return null;

I can get progress by publishProgress , but when progress = 100% then ImageView not show

Sorry , My English is bad :( .Help me !!
