Bear in mind that the code shown below runs on the UI thread. This means
the UI thread is blocked until the HTTP request returns. If the HTTP
request has a problem (e.g., the server is not responding), it could
very easily take beyond the ~5 seconds allowed before an
application-not-responding (ANR) error occurs and your activity is
forcibly closed.
I heartily encourage you to use a placeholder image when launching your
UI and have the real image downloaded off the Web in the background.
AsyncTask should work very well for this case -- you can download and
decode the image in doInBackground() and apply it to the ImageView in
onPostExecute().
