I've been continuing to work on my Android app, and have made some good progress. I have the layout of my main screen done, and also have my app integrating with Evernote, which is pretty cool I have to say. The Evernote API tutorial is very good, and I didn't have many issues while figuring out how to authenticate to Evernote via my application.

One of the main things I learned is, when designing your screen layouts, avoid the GUI if possible and configure the locations and settings of each object within the layout.XML file itself. If you move stuff around on the GUI, it will automatically adjust the XML file for you, but man it can make it ugly. Going through the struggle of figuring out how to adjust object locations via XML has a learning curve certainly, but you'll thank yourself later.
