DRM interface overview

The key elements of the digital rights management (DRM) system include MediaPlayer methods, the DRM class, and the DRMHelper class.

A reference to the object that implements the DRM subsystem:
```
MediaPlayer.getDRMManager();
```
The DRMHelper helper class, which is useful when implementing DRM workflows. You can see DRMHelper in the PMPDemoApp.

A DRMHelper metadata loader method, which loads DRM metadata when it is located in a separate URL from the media.

public static void loadDRMMetadata(final DRMManager drmManager, 
   final String drmMetadataUrl, 
   final DRMLoadMetadataListener loadMetadataListener);

A DRMHelper method to check the metadata to determine whether authentication is needed.

/**
* Return whether authentication is needed for the provided
* DRMMetadata.
*
* @param drmMetadata
* The desired DRMMetadata on which to check whether auth is needed.
* @return whether authentication is required for the provided metadata
*/
public static boolean isAuthNeeded(DRMMetadata drmMetadata);

DRMHelper method to perform authentication.

/**
* Helper method to perform DRM authentication.
*
* @param drmManager
* the DRMManager, used to perform the authentication.
* @param drmMetadata
* the DRMMetadata, containing the DRM specific information.
* @param authenticationListener
* the listener, on which the user can be notified about the
* authentication process status.
* @param authUser
* the DRM username provider by the user.
* @param authPass
* the DRM password provided by the user.
*/
public static void performDrmAuthentication(final DRMManager drmManager, 
final DRMMetadata drmMetadata, 
final String authUser, 
final String authPass, 
final DRMAuthenticationListener authenticationListener);

Events that notify your application about various DRM activities and status.
