Introducing Android

No doubt, you are in a hurry to get started with Android application development. After all, you are reading this book, aimed at busy coders.

However, before we dive into getting tools set up and starting in on actual programming, it is important that we “get on the same page” with respect to several high-level Android concepts. This will simplify further discussions later in the book.

Focus: Apps, Not Operating Systems

This book is focused on writing Android applications (“apps”). An app is something that a user might install from the Play Store or otherwise download to their device. That app usually has some user interface, and it might have other code designed to work in the background.

This book is not focused on modifications to the Android firmware, such as writing device drivers. For that, you will need to seek other resources.
