Actually, I was looking at your code some more, and *I would want to know
the URL you are downloading from* to get a better idea of the correctness.
I see that you are searching for an equals sign and using that to find the
file name.
If it turns out you are coming up with an okay file name, the problem is
almost certainly one of permissions - you will need INTERNET permission as
well as WRITE_EXTERNAL_STORAGE.
Thanks.
