mark murphy - GraphQL and Android .3

Headings formatted in bold-italic have changed since the last version.

Thanks!

Thanks for your interest in Android app development, the worlds mostpopular operating system! And, thanks for your interest in GraphQL,an increasingly-popular option for communications between clientsand servers.

And, most of all, thanks for your interest in this book! I sincerely hope youfind it useful!

But, however, bear in mind that it will not be funny.Not one little bit. This book will be completely serious, without anyjokes or other forms of humor. Honest.

(well, OK, perhaps not)

We start off with a quick spin through making GraphQL requests, usingcanned tools and custom Android apps. These chapters are designed to helpyou explore the basics of exchanging data via GraphQL, plus learn abouthow GraphQL compares with other ways that you have used to exchange data(e.g., REST-style Web services).

Next, we take a deep dive into GraphQL syntax. A GraphQL server publishesa schema, indicating what we can request or modify. In this series ofchapters, we will explore various facets of that schema and learn howwe can request or modify that data given the restrictions imposed by theschema.

Since this book is a work-in-progress, while there will be much more to come,that is all I can offer you at the present time.

Overall, the hope is that this book when completed will give you thorough grounding inhow to integrate your app with GraphQL servers.

This book will be updated a few times per year, to reflect new advancesin the world of GraphQL, new approaches for Android integration, and soforth.

If you obtained this book through, you will be able to downloadupdates as they become available, for the duration of your subscriptionperiod.

If you obtained this book through other channels um, well, its stilla really nice book!

Each release has notations to show what is new or changed compared with theimmediately preceding release:

• The Table of Contents shows sections with changes in bold-italic font
• Those sections have changebars on the right to denote specific paragraphsthat are new or modified

And, there is the Whats New section, just below this paragraph.

There are two (well, one-and-a-half) new chapters:

• One on paginated GraphQL queries, using the Relay connection pattern, and howwe can consume them in Android
• One partial chapter on advanced Apollo-Android techniques

In addition:

• All URLs in the samples and prose now point to 0.3/ instead of 0.2/in their paths
• The samples using Apollo-Android now use 0.4.0 of that library, which inturn necessitated a small build.gradle change, adding in an apollo closureand turning off semantic naming
• There are a few errata fixes and the like
