Android DRM Architecture

The DRM framework is designed to be implementation agnostic and abstracts the details of the specific DRM scheme implementation in a scheme-specific DRM plug-in. The DRM framework includes simple APIs to handle complex DRM operations, register users and devices to online DRM services, extract constraint information from the license, associate DRM content and its license, and finally decrypt DRM content.
The Android DRM framework is implemented in two architectural layers:

• A DRM framework API, which is exposed to applications through the Android application framework and runs through the Dalvik VM for standard applications.
• A native code DRM manager, which implements the DRM framework and exposes an interface for DRM plug-ins (agents) to handle rights management and decryption for various DRM schemes.
