When using an external downloader, self._make_cmd is considered as a list, not a str

[arter97]

On Python 2.7.2 ported over Android, using an external downloader results in an error.

Seems like _make_cmd function does not return the cmd as a str.
Using a simple workaround like "return str(cmd)" or "return str(cmd).encode()" still does not work

Please take a look and suggest me a fix.
Thanks :)

self._make_cmd is expected to be a list. ''.join(cmd) will do what you want.

I'm a little Python noob, so excuse me.
The message "TypeError: execv() arg 2 must contain only strings" says it did not get a str on subprocess.Popen.
If self._make_cmd is expected to be a list, where am I supposed to touch and fix?
