In the previous video, Marko walked you through the Android Stack. In this video, you'll be dissecting an Android app in-order to learn about all of the parts that make up the Android APK.
At the end of this tutorial, you'll have a good understanding of all of the important components in the Android APK, as well as becoming familiar with developing for Android in an Eclipse-based environment.
This video tutorial comes from Marakana's 5-day Android Bootcamp Training course.
