restfb
RestFB is a simple and flexible Facebook Graph API client written in Java.
It is open source software released under the terms of the MIT License.

Features

restfb has been designed with several objectives in mind. The most important of these are defined as follows.

Zero runtime dependencies

You don't need to include additional libraries in your project. There are no dependency conflicts. In addition, RestFB is highly portable and can be used in both Android projects and normal Java applications.

Maximal extensibility

Although we provide a standard implementation for our core components, each component can be replaced with a custom implementation. This allows RestFB to be easily integrated into any kind of project. Even Android projects are supported.

Minimal public API

TThe RestFB API is really minimal and you only need to use one method to get information from Facebook and one to publish new items to Facebook. We provide default implementations for all the core components, so you can drop the jar into your project and be ready to go.

Simple metadata-driven configuration

Our Facebook types are simple POJOs with special annotations. This configuration is designed for ease of use and can be used to define custom types very easily.

RestFB can be downloaded from Github or used as a Maven dependency. There is also a sample project on Github.
