Hi Renard,
Thanks for your reply, in that case I agree the internet permission
seems like the most sensible option. It's a pity it doesn't look
like it's possible to tie the network permission down to specific
URLs, so users could be assured nothing unpleasant was going on (I
think Chromium extensions can have this kind of "only allow on this
website" granularity).
I'm very happy to hear you're planning on releasing the code under GPL
or Apache. Either would be fab (though I'd probably favour GPL
personally, so nasty people would be less inclined to just take your
code and add advertising, but maybe this isn't much of a problem with
Android, I don't know).
I look forward to seeing the code :)
Nick
