New: Pre-Ordering links are now up at O'Reilly, Chapters-Indigo, and Barnes and Noble

We are building a community-written web site which will also be used to create an O'Reilly Cookbook, both about how to build great Android applications. It will be full of how-to information along with code snippets that illustrate the ideas presented. It will be complete, featuring 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 will have input from hundreds of contributors, who are already able to view and comment on each others' recipes before the book is published. The published version(s) will include printed books, eBooks, and other uses. And after the book is published, this site will continue to exist - with a larger collection of recipes than will fit in the published book - and serve as an Android developer resource site long after.

We 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; anybody can vote for existing recipes (voting indicates that you like the recipe and/or think it should be included in the printed edition of the book). 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 on the Add New Recipe form;
• 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.

Of course, everyone who contributes a Recipe gets credit for it on the site. In addition, everyone who contributes one or more Recipes that are chosen - at the editors' discretion - for inclusion in the printed work, will receive an ebook copy of the finished edition (readable in all supported O'Reilly eBook formats).
