IanDarwin/Android-Cookbook-Examples

Android Cookbook Examples

This repo is among the largest collections of Android code samples anywhere; it contains around a hundred and fifty compilable source code examples from the O’Reilly Android Cookbook, which was at its publication a great source of tutorial material for the Android Developer. Not all recipes in the book or online have code accompanying them; this repo features code that was either linked by the contributor, or in some cases, re-constructed as a New Project by the editor for your convenience.

Further note that not all programs used in the book/online appear here; some of the examples in the book/online are only program fragments taken from other programs that can’t be included. And of course some code is drawn from existing projects that are hosted elsewhere.

Each directory contains one project, and (if it’s used in the book) 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 project to maintain Android Eclipse development. However, it has become clear that AndMore has not attracted enough developer talent to 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 lists each project, its author, and a short summary.

*Note that, since Gradle and the Gradle Android Plugin need to be updated just about every time your run Android Studio, there is no attempt made to keep things up-to-date here; just let Studio do its upgrade thing for you and all will be well. They promise. Except for really old projects, where you’d have to upgrade 6 or 8 times. For these, copying newer build.gradle files from ../AndroidTemplate might be a better bet. Better yet, see https://darwinsys.com/blog/2022-07-26-modernize-android/.

DELETED/RENAMED PROJECTS

JpsTrack and the ToDo* applications have graduated to their own github projects, under https://github.com/IanDarwin.

The Hello*Test projects are moving to names starting with Testing…

DuellingIDEs has been removed since the duel is over. Just use Android Studio.
