Capture events from the navigation bar


You can capture and block the back, home, and navigation bar tasks.

Or hide it and never appear .

You can capture the events within the onKeyDown () method, for example the back button:

public boolean onKeyDown(int keyCode, KeyEvent event) {
    if(keyCode == KeyEvent.KEYCODE_BACK){
        //Se activo la tecla back!
    return super.onKeyDown(keyCode, event);

the home button

   if(keyCode == KeyEvent.KEYCODE_HOME)
       //Se activo la tecla home!

The third button I do not know how to do it, previous APIs did not allow the control of this button.
