The Android Cookbook is a crowd-sourced O'Reilly Cookbook about how to build great Android applications. The book is full of how-to information along with code snippets that illustrate the ideas presented; most of the code samples are available as complete projects on github. It features both how-to's that overlap with the official documentation, and material that goes beyond this to be more tutorial, more in-depth, or explaining "lessons from the trenches": what actually works to get the application functioning well.

Unlike most books written by one, two or a few individuals, this one has input from dozens of contributors, who were all able to view and comment on each others' recipes before the book was published. The published version(s) include printed books, eBooks, and other uses. An earlier version of this website was used to crowd-source the book and displayed the individual recipes, but that has gotten out of date and the recipes are no longer available online here.

We still welcome contributions from anybody who has something useful to say about how to make usable and successful Android applications. There are several ways of contributing: experienced Android developers can write recipes; newer ones can suggest recipes that they'd like to see; anybody can read and comment on recipes. To contribute a new recipe or comment on an existing one, please use this contact form. All we ask of contributors is the following:

• You agree to license your work - both the textual description and the code fragment(s) - under the Creative Commons Attribution cc-by License;
• When writing a new recipe, you put your contribution into the standard Cookbook form ("Problem", "Solution", "Discussion") as described in the contributing page.
• Only paste in code fragments that have been compiled and run;
• And of course you assert that the work is your own. Do not copy from others' books or published works; if we wanted to reprint existing stuff we could just find it on the web. And if you are working for an organization, you assert that you have permission to use portions of their code.

Everyone who contributed a Recipe that was chosen, or who yet contributes a new recipe that is chosen - at the editors' sole discretion - for inclusion in the published work, receives an ebook copy of the finished edition (readable in all supported O'Reilly eBook formats). And their name is of course included in the book.
