Last year after the Android SDK was released, I wrote a small app that allowed me to upload photos and update my facebook status with a native application. Here is the result. I re-implemented a subset of the official facebook API because I didn't understand it. (It wasn't "not invented here syndrome" it was more of a "I am not smart syndrome"). Anyways, I've posted the code at statusinator.googlecode.com and there is a Facebook app page as well.
