I had made an computer application to send data on wifi but on android side i m not sure how to forward data from my android to arduino mega board via USB port. please help if itis available in ketai lib .

Hello,
I don’t know if a mega usb is available on android side. I think serial communication from android side with processing isn’t available at this time.

You can use a arduino shield with bluetooth, with the ketai samples.

Or use a wireless lan – serial device like an wizfi210, connect it to a serial port on arduino side and use java default socket communication to speek from android-processing to your arduino.
