Controlling the GPIO from Android

[Massimo Banzi]

Hello

I'm looking for suggestions on how to drive the GPIO pins on the beagleboard from Android.
I would imagine the best way would be to write a native library that gets loaded by some android intent and
made available to the other apps.

do you guys have any suggestion?

somewhere I can look at?

maybe it has been done and I haven't found it :)

thanks

hi Massimo,

You can refer to the classical HelloJNI example for accessing native
library. However, be aware of the
permission issues if your C library attempts to do ioctl. I would
suggest to write a dedicated system
service with the interface exporting to binder.
