I am completely new and don't understand what is wrong with my code. Could you just edit it and then reply it so that I can copy paste it : <p>Please just edit it and reply it.
I don't want to learn any coding but just want to create an app.
This app function is to just display a youtube site with a banner ad and interstitial ads
 the errors which it is showing are these
Error:(39, 5) error: illegal start of expression
Error:(39, 12) error: illegal start of expression
Error:(39, 33) error: ';' expected
Error:(53, 5) error: illegal start of expression
