Hi Forum,

I've been trying to write an piece of code in Android mode in Processing to my HTC Desire's bluetooth to communicate with Arduino.  I am using Processing 1.5 / Android 2.1 (API Level 7)

I have tried using the Amarino library and also had a little play with the SweetBT library but when trying to compile I get the following error:

1.

Has anyone had any success with Amarino or SweetBT compiling to Android?  Can anyone help?

Thanks
