Greetings!

I seek some support for Arduino USB Host of an Android Accessory.
REF: https://www.arduino.cc/en/Tutorial/AndroidAccessoryDigitalWrite

Any thoughts regarding additional information regarding the ArduinoAdkUsb object?
The Processing sample code from the Android Accessory Digital Write tutorial contains the following:

import cc.arduino.*;
import android.view.MotionEvent;
ArduinoAdkUsb arduino;
...
arduino = new ArduinoAdkUsb( this );
arduino.connect( arduino.list()[0] );
if ( arduino.isConnected() ) {
    if ( event.getAction() == MotionEvent.ACTION_DOWN )
      arduino.write('a');

The end goal is to use the Arduino USB Host Shield to control the Arduino I/O from cost effective Android hardware with open-source libraries for Arduino Accessory Development Kit (ADK) and Processing 3.

Thanks,
coast
