This document provides an overview of an Android development course for beginners from Udacity. The 6-week course covers building layouts using views like TextView and ImageView, making apps interactive using layouts like LinearLayout and RelativeLayout, and object-oriented programming. Key lessons include building the app structure and interface with XML, adding interactivity with buttons and listeners, and learning Java concepts like classes and objects. The goal is for students to gain foundational Android skills and build a simple calculator app by the end of the course.

3. What is Android ?
 Android is a mobile operating system developed by Google
 Based on the Linux kernel and designed primarily for touchscreen mobile devices
such as smartphones and tablets.
 Android's user interface is mainly based on direct manipulation, using touch
gestures that loosely correspond to real-world actions,
 Such as swiping, tapping and pinching, to manipulate on-screen objects, along
with a virtual keyboard for text input.

4. Why This Course ?
 While Android has evolved over the years, iOS has as well, even adopting plenty of
early Android features that once made this the easy operating system of choice
for many of us.
 Is it about control, still? Is it the “openness” to everything (like apps talking to each
other and a file manager)? Is it about choice?
 Is it because you just flat out love HTC or Samsung or Motorola or LG?
 Is it because you need the best Google app experiences (sans Hangouts of
course)?
 Or maybe, you really just do despise all that is Apple?
