Socializen is a project mainly written in JAVA and SCALA, it's free.
Auth and social services for use in PlayN-based games.
This library provides cross-platform bindings to popular social networking APIs for use by PlayN games. Much like PlayN, a game is written against a generic API, and implementations are provided for each supported PlayN platform (Java, GWT, Android, etc.).
Because the process of configuring an app on a single platform for a single social network is complicated, we cannot hope to explain, in a simple manner, how one goes about configuring their app to work across multiple social networks and multiple platforms. If you are familiar with a given social network's APIs and configuration process, you will likely have no problem profiting from this library.
If some ambitious community member wishes to provide documentation on how to get things working on one or more combinations of social network and platform, we'll gladly incorporate it, though it will likely rapidly fall out of date as these social networks evolve their APIs and configuration process at break-neck speeds.
The library is built using SBT or Maven.
Invoke sbt publish-local to build and install the library to your local Ivy
repository (i.e. ~/.ivy2/local).
Invoke mvn install to build and install the library to your local Maven
repository (i.e. ~/.m2/repository).
