I am new to android development and have a few questions.
1: Can I make android devices read and use the information from the Wii controller and nunchuck? The fun
Yes, the wii controllers are all bluetooth. You can pair your android device with any bluetooth device. There are actually apps already in existence that do this (android-wiimote) available.
If you look through the source code of imame4all, they actually demonstrate this support.
In particular, this should start you off.
Have a look at this open source project: http://code.google.com/p/android-bluez-ime/
