The Samples folder, ../%sdk folder%/SAMPLES, contains six sample applications that demonstrate a good cross-section of Android functionality:
● API Demos
● Hello, Activity!
● Lunar Lander
● Note Pad
● Skeleton App
● Snake
These sample applications are provided by Google to give you a quick idea of how to develop an Android application. Each sample application demonstrates a different piece of Android’s functionality. You can open and run these applications from within Eclipse. Following is a brief description of each.
API Demos
The API Demos application is a host application that demonstrates multiple API functions
in a single Activity.
TIP
An Activity is an Android application. Activities are covered in more depth in the following chapters.
The API Demos application, as shown in the following illustration, contains multiple, smaller, examples of different Android functions:
Some of the applications included in the API Demos sample include 3-D image transitions, list and progress dialog boxes, and a finger-painting demo.
