Hi,
this one could be for you: http://arduino.cc/en/Main/ArduinoBoardADK
ADK provides the API and on Android side, since 2.3.4 I believe. You can use all of Arduinos features to wire your hardware, you can even do time-critical things on it. But you have to code on both devices.
Sparkfun had another interface kit for Android which worked also with older versions: https://www.sparkfun.com/products/10585
