Have a look at this JNI for Android.

I believe you need to do this JNI when using Java to access IO.

Hello,
i'm interested in using GPIO (I2C, UEXT) from java on Debian (not Android), but i can't find a simple (but complete) example.

Maybe this will help?

As you need access to the native drivers you need a JNI to do this but the above may be an alternative.

I don't use or programme under Debian but the use of JNI in Android seems to be the same.
