Android webview get keycode problem

I am looking for a freelancer who are expert in android. I have got a problem with webview as I want to capture the keycode, but I am unable to do as I have tried number of ways, e.g: using javascript, dispatchKeyEvent and InputConnection. It will work on InputConnection but I dont know how to remove the number from 1 to 0 on the IME keyboard. I want you to have a look and see if you can capture to get the keyboard code. Will pay $40 after the work is done. Thanks for your interest.
