Hello Shouldn't you be testing for the HTTP status code ? Just a quick example: you can get zero-byte content in case of a redirect from the part of the server (3xx status code). In this case I see there is a flag to automatically follow redirects (HTTPUrlConnection.instanceFollowRedirects), but I don't see that you set it. But in all cases you need to test the HTTP status code.
