Looking at your code, it seems that you print the String variable
Output. This variable contains the value of the URL but you never set
it to anything else. I think you want to set a variable to the return
value of your downloadUrl method.
And some unasked advice with regards to dealing with the retrieving of
the http content. I retrieve the data directly with the HttpEntity
class as followed:
(I use a Post because i use it to post data to a external server, but
it works the same)
HttpPost siteRequest = new HttpPost(url);
HttpResponse httpResponse = client.execute(dataRequest);
responseData = EntityUtils.toString(httpResponse.getEntity());
After this responseData contains the http content retrieved from the
request.
