Creating an Android OAuth 2.0 client using an Authorization Code with the system browser

This recipe presents you with how to create a native OAuth 2.0 client application for Android, which integrates with an OAuth 2.0 protected API using the Authorization Code grant type. The OAuth 2.0 specification (RFC 6749) states that public clients shouldn't use the Authorization Code grant type. On the other hand, the recently published RFC 8252 states that Authorization Code should be used in conjunction with dynamic client registration and PKCE validation (we will see more about both approaches later in this chapter).

Note

The application created for this recipe, uses client id and client secret issued by a pre-registered client application just for brevity of the recipe. But bear in mind that, as per OAuth 2.0 specification, the Authorization Server must not issue client secret for native client that aren't specific running on a specific device.

Adolfo Eloy Nascimento

Adolfo Eloy Nascimento is a software engineer at Elo7, he has a Bachelors degree in Computer Science, and has been working with software development since 1999. In around 2003, he started working with web development implementing applications using ASP, PHP4/5, JavaScript, and Java (sometimes he still does some maintenance for a Ruby on Rails application). He started using OAuth 2.0 two years ago, when designing applications using microservice architectures, as well as modeling and interacting with public APIs. As a tech enthusiast, Adolfo also likes to read and learn about programming languages and new technologies. He also believes that besides creating new applications, it is also important to share the knowledge he has acquired, which is what he does by writing for his personal blog, writing articles for Java Magazine in Brazil, and also writing tech books.
