Android plugins add View

How can I add View into my android app? Actually I need to integrate Smaato ad and it would be awesome if someone show me an example of making this kind of plugins - I need to modify manifest, add view and then call some methods from .jar. Also maybe I can buy Smaato plugin somewhere?

I’ve done a youtube video covering exactly how to go about doing this, please find it here:
