Hello,
PdDroidParty is, I think, the easiest way to get your patches running on your Android devices. It emulates Pd native user interface elements (only toggle and slider implemented so far) so all you need to do is name your patch droidparty_main.pd and copy it to your SD card.
Download and install the apk from here, and then try out the drum machine example by unzipping it to your SD card:

This is beta software hot off the compiler, but I think it's just ready enough for use. As always, patches welcome!
Goodnight!
Chris.
PS oh yeah, get the source like this: bzr co http://mccormick.cx/dev/PdDroidParty/
