In this tutorial, I decided to cover all of the topics I would need, so that in every tutorial that follows I can just make apps. Don't try to memorize everything! Here I'm just covering a bunch of things you need to be familiar with.
We'll cover the lifecycle of an Android activity completely. We'll then look at how to make an app support many languages. We'll look at how to grab string resources and how to pull them into java and xml files. Finally, we'll look at the AndroidManifest.xml file in detail.
