Question

From the answers in the stackoverflow I found that Home button can be overriden?
But I found an application in the android market called “Mxplayer” where you can lock all buttons while playing video. How are they doing this?
Can we override the home button in android?

Answer 1

This solution works upto 2.3,

Override the below method in your Activity,

@Override
public void onAttachedToWindow() {
    super.onAttachedToWindow();
    this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);           
}

And now handle the key event like this,

@Override

public boolean onKeyDown(int keyCode, KeyEvent event) {

   if(keyCode == KeyEvent.KEYCODE_HOME)
    {
     Log.i("Home Button","Clicked");
    }
   if(keyCode==KeyEvent.KEYCODE_BACK)
   {

        finish();
   }
return false;

};
