Android Cookbook Examples
This repo is among the largest collections of Android code samples anywhere; it containsaround a hundred and fifty compilable source code examples fromthe O’Reilly Android Cookbook, a great sourceof tutorial material for the Android Developer. Not all recipes in the book or online have codeaccompanying them; this repo features code that was either linked by thecontributor, or in some cases, re-constructed as a New Project by theeditor for your convenience.
Further note that not all programs used in the book/online appear here; someof the examples in the book/online are only program fragments taken fromother programs that can’t be included. And of course some code is drawn from existing projectsthat are hosted elsewhere.
Each Directory comprises its own project, and has a name that is cited at the end of the corresponding Recipe, under the "Source Code Download" section.
Some older started-in-Eclipse projects also have configuration files to allow them to be opened in Android Studio.During the runup to the second edition of the book, AndMore appeared to be a viable projectto maintain Android Eclipse development.However, over time, it has become clear that AndMore has not attracted enough developer talentto remain viable.Accordingly, the newest projects here are Android-Studio-Only.And Issue #1 calls for moving the existing mass of projects to Studio-only format.For reference, a "canonical" project would look something like this:

The table List of Projects shows lists each project, its author, and a short summary.
*Note that, since Gradle and the Gradle Android Plugin need to be updatedjust about every time your run Android Studio, there is no attempt madeto keep things up-to-date here; just let Studio do its upgrade thing for youand all will be well. They promise.
DELETED PROJECTS
JpsTrack and the ToDo applications have graduated to their own github projects, underhttps://github.com/IanDarwin.
