Where can I find “Facts” Android app source codes?

Question by SandMan: Where can I find “Facts” Android app source codes?
There are many “Facts” apps in the Android Market (Health facts, Internet facts, etc.). I would like to develop an app similar to these too. Does anyone know where I can get the source code for one of these types of applications? I’ve just started learning Java + XML, and I figured that it would be a lot faster to look at the codes and decipher/learn from them, than to slowly write my own programs from scratch.

I don’t plan on publishing apps for the Market. I am planning to use them for personal use and for my student group in my University.
@Luke: Yes, you can get the source code. Provided the app is an open source project, or the app developer is willing to share it. Problem is, I haven’t found any “_____ Facts” source codes yet.

I don’t think you can unless the owners send the source code to you, however there are example applications at the Dev part of the android site.
