I just started using their Android SDK(written in JAVA) for consuming web services. You can also use Retrofit library to consume DSP web services and serialize to POJO. they have good documentation.
The authentication part is trouble for me. As per my understanding, we can use their User API to register new users or use OAuth. But my use case is different and so I’m waiting for DSP 2.0 release which promises to provide an easy way for authentication. Register for their beta program. just FYI
