Summary

In this chapter, we showed you a fun way to enhance your UI programs by extending them with animation capabilities. We covered all major types of animation supported by Android, including frame-by-frame animation, layout animation, and view animation. We also covered supplemental animation concepts such as interpolators and transformation matrices.

Now that you have this background, we encourage you to go through the API samples that come with the Android SDK to examine the sample XML definitions for a variety of animations. We will also return to animation briefly in Chapters 10 and 13, when you'll see how to draw and animate using OpenGL.

But now we will turn our attention to services in Android. We'll cover location-based services and security in Chapter 7, and HTTP-related services in Chapter 8.
