Integrate different video ads

Android Android Development
1

I would like to play video ads in my app in a random way when you click a button, but I don’t know if the way i think to do that is correct or not. I was thinking about something like this:

final Button button = (Button) findViewById(R.id.button);
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view ) {
            mpButtonClick.start();
            clicked++;
            text.setText("          " + clicked);


            adcompany1.playAd();
            adcompany2.playAd(); 



        }
    });
}

This is a general case , but I guess that what I would like to do it’s pretty clear. adcompany1 and adcompany2 are two different hypotheticals ad companies. Is this a correct way or not?
