Digital Rights Management

 

The Android platform provides an extensible DRM framework that lets applications manage rights-protected content according to the license constraints that are associated with the content. The DRM framework supports many DRM schemes; which DRM schemes a device supports is left to the device manufacturer.

The Android DRM framework is implemented in two architectural layers (see figure below):

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
