GUI Layout Google documentation walks you through a basic "Hello World" application; this sample makes use of the plug-in and its default application.

Developers can try that out if they-ve downloaded the SDK and Eclipse. One thing I want to mention in particular is something that makes development for Android easy. Most of today's development tools allow for easy development of a GUI by describing the GUI rather than coding it. Instead of calling an API function to add three buttons to a window, a user describes the three buttons and the run-time does the hard work of reading the descriptions and adding the buttons to the window. This concept isn't by any means new-early Mac and Windows developers have used resource files for ages, and today we have

As you would therefore expect, especially considering this is Java we're using, the GUI development includes a full set of layouts, such as a table layout, various list layouts, absolute layouts and others.

Conclusion: Where to Go Next

I found the best place to understand how everything fits together is to read three articles in particular from the official documentation in this order:

code.google.com/android/intro/anatomy.html and

code.google.com/android/intro/appmodel.html for information on the application model, and then

code.google.com/android/intro/lifecycle.html for information on the application lifecycle.

Understanding these three documents is vital to understanding how Android works.
