Android avd arrow keys not working

Issue

I am learning app development from a book, and have run into a problem with the avd. I have my code set up to change some text when the right arrow key is pressed:

public boolean onKeyDown(int keyCode, KeyEvent event){
            if(keyCode==KeyEvent.KEYCODE_DPAD_RIGHT){
                textUpdate();
                return true;
            }
            return false;
        }

When I run the virtual device and press the arrow keys nothing happens. When I press the arrow keys on my physical keyboard, still nothing. I have done a lot of research and can't find the solution. I have tried editing the avd settings and editing the device(Nexus One) itself to accept keyboard and dpad input. What should I try now?

Solution

Alright, what happened was my onKeyDown() function was inside a Fragment. I don't know why, but when I moved this code into the mainActivity it worked fine. If anyone has an answer as to why this worked and how I could get it to work in the fragment please comment.

Thanks
