DRM framework for Android platform.

Android DRM framework offers an abstract, unified API that simplifies the management of rights-protected content. The API hides the complexity of DRM operations and allows a consistent operation mode for both rights-protected and unprotected content across a variety of DRM schemes. For device manufacturers, content owners, and Internet digital media providers the DRM framework’s plugin architecture provides a means of adding support for a specific DRM scheme to the Android system.
