Answer 1

Since Android 4 there is no effective method to deactivate the home button. That is the reason why we need another little hack. In general the idea is to detect when a new application is in foreground and restart your activity immediately.

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;
}

Put his into your activity's code. It will intercept back button click

  @Override
public void onBackPressed() {

}

Answer 4

u can ovverride home button pressed like this:

@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);
}
