Premium / Free Versions of App using Libraries?
<p>I've read up on and have a pretty good understanding of Library projects in Eclipse, but there's one functionality of it I don't understand. I'd like to declare one of my Apps as a library project and use it to create a premium, paid app and a free, ad-supported version. I've heard that this is possible, but I'm still not sure exactly how I'd make it work.</p>

<p>My experience with Libraries is to use them to provide frameworks for other Apps to utilize. That's the area I'm having trouble figuring out; in essence, I wouldn't be adding anything to the project, but modifying some of the layout files to add an ad banner view, so I'm not sure how to make a project overwrite a Library file, or if that's even the right thing to do.</p>

<p>Can anyone please give any ideas of how I might achieve this? Thanks!</p>
