This article is the first part of a tour around the Android platforms: Android TV, Wearable and Auto. We wrote down the crucial things that you should know before you get into building apps. We will not show you how to build applications for these particular platforms step by step, but you can find more resources which will help you do so on the Android Developer site. What we want to do here is show you the minimum requirements and restrictions you must know before you start. Hopefully this will help you build an efficient and effective application.
