This YTApp is simple android app that allows you to create list of videos from youtube and share with others. It comes with downloader function where user can either watch via streaming or download and watch later. It is extremely simple to configure (you’ll just need to follow the steps in the documentation provided) and you can start to build and publish to appstore (and of course monetize with best ads network: admob and startapp).
Why this is good for you:

2) Comes with necessary ad network integrated (infact the best ad network)
3) Come with handy function such as search, share and ratings.
