So excited to find out the new port. I just posted a feature request to have the Android version offically support the SonarPen, a very affordable pressure sensitive stylus that I have developed. The SonarPen is compatilble with any Android device that has a capacitive touch screen, and will turn it into a drawing pad.
For those who has the programming talent and interested in adding support of SonarPen to the Android port, please contact me. Android SDK and sample is ready.
