I wrote a widget called p2poolwidget for android a while back.  I think if you search for p2pool in the google play store it's still the only relevant app you'll find, sadly.  Anyway, I wrote it back when I was mining, which I haven't been doing in a long time, just so I could monitor my setup.  I was trying to learn android programming at the time, so the code is pretty sloppy.  I'd planned to try to improve it over time, but then mining on p2pool started becoming less and less rewarding and mining in general became unprofitable for me soon after, and I just lost interest basically.

So, I haven't made any updates in quite a while.  Then someone emailed me a few weeks ago asking for some changes, and I told them I didn't really have time, and they asked if I would consider open sourcing it.  So I put it up on github a couple of weeks ago.  I was going to wait until they confirmed they were able to get the code to compile, but I'm pretty sure it's all there (if not, sorry, it's first time using github).  So, basically I thought I'd mention it here in case any one in this thread wants to make their own changes.  You should be able to get to it here: https://github.com/ksenter/P2PoolWidget

If you want to release your own version, just give me credit for any of the code, or ideas, of mine that you keep.  Other than that, have at it.  Good luck!
