One thing I wish I had discovered earlier is that some devs from Google released the sources for a "Google I/O" app for the last two years, and that reading that code teaches you a lot of how to design a good app. The Google I/O app uses (and sometimes introduces) many useful patterns in UI design and Architecture design. It scales to all kind of screen sizes, hardware configurations and platform versions. Here is a link to a resource page for the Android Developer Lab in Paris. You can find links to Google I/O 2011 and two other examples there. https://sites.google.com/site/androiddevlabs2011/code-lab-paris https://sites.google.com/site/androiddevlabs2011/code-lab-pa...
