Maybe some of the requests are getting blocked. Try adding connect and
read timeouts by replacing url.openStream() with
openConnection().getInputStream():
...
URL url = uri.toURL();
URLConnection con = url.openConnection();
con.setConnectTimeout(3000);
con.setReadTimeout(3000);
Bitmap bmp = BitmapFactory.decodeStream(con.getInputStream());
...
Adjust the 3000 ms timeout values if necessary.
You can add exception handling for the connection timeouts.
