Answer 1

Use like this.If now you are in LastActivity and you want to go back to the First Activity and there is more activity in between then if you want to go first from last use

@Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if(autoSearch)
        if (keyCode == KeyEvent.KEYCODE_HOME) {
           Log.d("click","HOMEButtonclicked");
          LastActivity.this.startActivity(new Intent(LastActivity.this, FirstActivity.class));
           moveTaskToBack(false);
           return true;
        }
        return super.onKeyDown(keyCode, event);
    }
