Disable home button in Android

Due to the security reason ICS is not allowing to disable home button in android after 4.X ; it is possible  before 4.x version of android;

Code Snippet  :

@Override

        public void onAttachedToWindow() {

              LoadFirstPageObject();

           this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD_DIALOG);

            super.onAttachedToWindow();

        }

And you can throw the own handle type by

@Override

        public boolean onKeyDown(int keyCode, KeyEvent event) {

            if ((keyCode == KeyEvent.KEYCODE_HOME)) {

             

               // Toast.makeText(this, "You pressed the home button!", Toast.LENGTH_LONG).show();                     

                return true;

            }

           

            return super.onKeyDown(keyCode, event);

        }

Below code will create problem exception in 4.x as illegal illegalargumentexception;

It won't work on Nexus

  this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD_DIALOG);
