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, 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 comprises its own project, and has a name that is cited at the end of the corresponding Recipe, under the "Source Code Download" section.

NOTE There are two styles of projects:

Eclipse projects with the newer Eclipse Andmore;
Android Studio projects (most of them complete with their extraneous "app" subdirectory).

If you have used the old Google ADT, you will need to update your Eclipse config by removing ADT, then replace it with AndMore from the Eclipse Marketplace Client.

Most of the Eclipse projects also have configuration files to allow them to be opened in Android Studio.

Many of the Eclipse projects have been Mavenized; a few have not.

Most of the Gradle projects will also build with Android Studio; there may be a few that will not.

The table List of Projects shows which projects are set up for which build tools.

TL;DR: Build Most Projects with Apache Maven

Prerequisites: Java 7 or 8 SDK, Android SDK including "Google Maven Repository" for compat stuff, git, Maven

git clone https://github.com/mosabua/maven-android-sdk-deployer
cd maven-android-sdk-deployer
mvn install -P 6.0 # at least
mvn install -P 7.0 # also needed
cd ..
git clone https://github.com/IanDarwin/Android-Cookbook-Examples
cd Android-Cookbook-Examples
mvn -fae package android:install android:run Include android:install and android:run only if you actually want to run them all, and have a device or emulator with some good free space; else just do 'package')
Fix up any that didn’t work, and send pull requests!

Eclipse Issue

If you get Eclipse-Maven projects failing with this message: org.codehaus.plexus.archiver.jar.Manifest.write(java.io.PrintWriter)

then you need to update your "M2E Connector for Android" to at least 0.17.2.20060614

Maven Build: More Details

About two thirds of these projects were initially developed using Eclipse ADT, and migrated to Maven for automatic building. Obviously Google has spoken and we will eventually have to migrate kicking and screaming to Android Studio and Gradle, but for now, we are keeping those projects in "bilingual" or "either-IDE mode".

If you import the entire repo in Eclipse with eGit, be sure to check the Import all projects checkbox. If you want to keep these mini-projects separate from your "regular" work, you may want to use the Git repo as an Eclipse workspace (use File→Switch Workspace→Other→Browse). This directory is already set up to be an Eclipse workspace if you want it to (the .metadata directory exists and is already in .gitignore).

Note: As part of the move to Gradle, Google stopped pushing Android releases to Maven Central; their last version was 4.1.1.4, thus Lollipop, Marshmallow, and "N" have been left high-and-dry. And worse, their SDK license prohibits re-distribution of binaries, so nobody else can step in and upload these files to Maven Central. But of course there is a solution. To compile these projects with Maven you will need to download the amazing maven-android-sdk-deployer, which repackages files from the SDK - after you download it using the Android tools, thus nobody is redistributing it - into your local .m2/repository so that Maven can find it. This is the function of the first few steps in the numbered list above.

Note that projects using official releases use e.g. com.google.android:android:4.1.1.4 whereas projects deployed using the sdk-deployer use e.g android:android:6.0_r3.

You can download AndroidCookbookExamples as a Zip file from GitHub, but then you won’t get updates, and it will be hard to collaborate with the other contributors. If you’re not familiar with Git and Github, see the getting started page on GitHub and read up on how to collaborate. You can either send diff/patch files or send a pull request. Remember that GitHub is a free service for public projects!

Many of the projects may (depending on your version of Eclipse) give you some noise when you first open them due to bin and/or gen being missing. The Eclipse plug-in will usually create them but not notify that it’s done so, meaning you just have to do Refresh (F5), failing that, close and re-open the project. Does not happen with current Eclipse, last I tried.

There is neither a Wiki or a Tracker for this Github repository. If a project won’t open, or won’t build, we’d prefer that you fix it and sent a pull request. Bugs and suggestions about code samples can be made on the Android Cookbook web site (http://androidcookbook.com/). Bugs or suggesions on the published edition of the book should go to http://shop.oreilly.com/product/0636920038092.do; you can also purchase the book there (which helps fund my continued work on this code base).

Notes for the First Edition of the book

The current version of this repo has been reorganized in preparation for the second edition of the book. There have been quite a few projects added since the first published edition of the book, and a few renamed, so if you have the printed edition from 2012 you should rummage around here before re-typing anything that looks like a full example.

If you want this repo to correspond to the last minor revision of the first edition, use git to checkout the tag Book-1.0.

DELETED PROJECTS

JpsTrack and the ToDo applications have graduated to their own github projects, up one level from here on Github.
