[android-developers] Re: fiel download, java.net.URL, streams

Did you allow INTERNET permission?

I don't know why do you did this: http.connect(); if you already
connected: url.openConnection();

Please, test your connection for available bytes, maybe your stream is
empty, if looking on that: URL url = new URL("http://
www.google.at/");
