Welcome to the source code for Android Programming Tutorials (http://commonsware.com/AndTutorials)!

Specifically, this is for Version 3.2 and above of this book.
For the source code for older versions of this book, please

The names of the top-level directories roughly correspond to a
shortened form of the chapter titles. Since chapter numbers
change with every release, and since some samples are used by
multiple chapters, I am loathe to put chapter numbers in the
actual directory names.

If you wish to use this code, bear in mind a few things:

* The projects are set up to be built by Ant, not by Eclipse.
  If you wish to use the code with Eclipse, you will need to
  create a suitable Android Eclipse project and import the
  code and other assets.

* You should delete build.xml from the project, then run

    android update project -p ...
  (where ... is the path to a project of interest)

  on those projects you wish to use, so the build files are
  updated for your Android SDK version.
