End to End Android Development
About the Bundle
We've all seen it. That amazing app that solved all your problems.. and turned your phone into a coffee warmer.
The developer had a great idea but is doing too much work on the device. It's downloading too much data, trying to process it locally, keeping connections open, and killing your battery cutting you off from everything and everyone.
The only solution is to move that work off the phone and back to the server via APIs. To do that well, your API has to be well planned, thoughtfully designed, and easy to use.
With this bundle, you'll be equipped to design and build API-driven Android apps from the frontend to the backend.
In A Practical Approach to API Design, we work to help you understand who will be using your API and why, what problems you need to prepare for, and how to solve many of those problems. Nouns, verbs, routing, and versioning are all discussed to make sure you build the right thing.
In Retrofit: Love Working with APIs on Android, we'll dig into what it takes to build Android clients that can handle the features and functionality that your application needs. We'll demonstrate how to authenticate via processes like OAuth 2.0, upload files properly, handle errors, and generally build and release an application you can be proud of.
The target audience for this bundle is developers who need to architect an application from front end to back end, already know the basics of Android, have experience with a backend programming language, and want to add Retrofit to their toolbox to use the great APIs they're designing.
About the Books
Retrofit: Love Working with APIs on Android
Take delight in building API clients on Android.
Painless Networking with Retrofit
The content of this book is completely updated to Retrofit 2.5!
Every modern Android app needs to connect to at least one private or public API. Interacting with services can be difficult due to the extreme variety of request and response formats. Depending on the API, you’ll need to change your request payloads, authentication, data formats, and much more.
Retrofit: a type-safe HTTP client for Android and Java
Retrofit handles all of the complicated and repetitive parts of network implementations for you. It hides the entire network layer, from creating a connection to processing the handling on a separate thread, from you. Retrofit even does the mapping of the requests and responses to Java objects for you (e.g., creating a JSON payload from your passed List<User>
). You only need to describe what and how you want to send or receive it.
This awesomeness comes at a cost: an initial learning curve. Retrofit might look a little more complicated at the beginning, but pays off multiple times in the long run.
If you’re thinking about using Retrofit, or haven’t developed a deep knowledge of it yet, you’ll benefit from this book. We’ve created this book with the vision of being the ultimate guide to understanding Retrofit. After working through this book, you’ll be able to connect to new APIs and services within minutes.
You can find a Retrofit tutorial series on our website and our free video tutorial series on YouTube, where we describe some elements of Retrofit. The book extends and connects these tutorials into one common thread that guides you through all important aspects of Retrofit. The chapters are structured in a way that rewards a linear reading. Retrofit rookies can and should read it cover to cover. Experienced Retrofit developers can jump to specific sections for guides on how to solve their specific problem.
What Topics Are Covered in This Book?
The list below provides a comprehensive overview of covered topics in the book.
- Introduction to Retrofit

Who Is This Book For?
In short: this book is for you. We believe that every developer reading this book will take away new ideas on how to optimize their Android apps in the sense of interacting with APIs or web services using Retrofit. You’ll recognize goodies that are applicable for the projects you’re working on.
This book is for Android developers, who want to receive a substantial overview and reference book on Retrofit. You’ll benefit from clearly recognizable code examples related to your daily work with Retrofit.
Rookie
If you’re just starting out with Retrofit (or coming from another HTTP library like Android Asynchronous Http Client or Volley) this book will show you all important parts on how to create sustainable REST clients on Android. The provided code snippets let you jumpstart and create your first successful API client within minutes!
Expert
If you’ve already worked with Retrofit, you’ll profit from our extensive code snippets and apply the learnings to your existing code base. Additionally, the book illustrates various use cases for different functionalities and setups like authentication against different backends, request composition, file uploads and downloads, and much more!
One focus of this book is not only to implement the requirements, but also do so in a clean way. We’ve seen way to many complicated and messy usages of Retrofit. We focus on providing code samples which adhere to clean code standards. We avoid any unnecessary duplication at all costs. This has the side effect of some extra app performance gains by efficient Java object handling.
Source Code Samples
With the purchase of this book, you benefit from the sample project that awaits your download within the extras section on Leanpub. The sample project is an Android project based on gradle. You can directly touch and use classes that are only illustrated in excerpts within this book.
Check your Leanpub Library and select Retrofit: Love working with APIs on Android to download the sample code base.
Continuous Updates
We’ve published the first version of this Retrofit book in July 2015. Since this initial release we’ve extended and updated the book more than a dozen times. Once you buy the book, you get all future updates for free. Even if it’s a huge Retrofit update, for example from version 1.9 to 2.0. With every new release of Retrofit we’ll evaluate the entire book content and update it accordingly.
Of course, we’re listening to your feedback and add new sections and even chapters, if it can be useful to all readers. If you still have a question after reading this book, let us know and we might be able to help!
Still Unsure?
If you’re still on the fence if this book helps you, checkout the sample or, even better, use Leanpub’s (and our) happiness guarantee. Try this book out and if you don’t think this book provides enough value, you can refund your money within 45 days with no questions asked. You don’t have any risk in testing this book, which saves you hours of headaches and makes your Android app code so much cleaner.
Final Note: Retrofit Book for Version 1.9
The current version of this book is fully focused on Retrofit 2.x, no hint or code snippet that points to Retrofit 1. If you’re interested in the first version of the book that based on Retrofit 1, please visit this book’s extras page on Leanpub. As a reader of this book, the first version is also available for you!
A Practical Approach to API Design
From Principles to Practice
If you read the tech press, everyone knows they need an API but most aren't really sure what it is. They treat it as another checkbox like "Web 2.0" was a few years ago or a mobile app was most recently. In fact, there's an entire "API-first" movement in development circles that most people don't understand or even realize why. In this book, we'll start by discussing the what an API is, why you might need one, and follow up with the how to build one.
With addition of our Appendix on API Design Patterns and numerous other design tips, this book is complete. Regardless, we're always open to additional sections, concepts, and questions so don't hesitate to drop us a note. Further, when you find something interesting, let us know. If you think we’re wrong, say so. If you think we’re right, tell your friends. If you want us to teach your team more and deeper concepts, please let us know.
