  - queryKeyStatus
```
public Map<String,String> queryKeyStatus(byte[] sessionId)
```
    Description copied from interface: ExoMediaDrm
    
    Returns the key status for a given session, as {name, value} pairs. Since DRM license policies vary by vendor, the returned entries depend on the DRM plugin being used. Refer to your DRM provider's documentation for more information.
    
    Specified by:
    
    queryKeyStatus in interface ExoMediaDrm
    
    Parameters:
    
    sessionId - The ID of the session being queried.
    
    Returns:
    
    The key status for the session.
  - requiresSecureDecoder
```
public boolean requiresSecureDecoder(byte[] sessionId,
                                     String mimeType)
```
    Description copied from interface: ExoMediaDrm
    
    Returns whether the given session requires use of a secure decoder for the given MIME type. Assumes a license policy that requires the highest level of security supported by the session.

    sessionId - The ID of the session.
    
    mimeType - The content MIME type to query.
  - acquire
```
public void acquire()
```
    Description copied from interface: ExoMediaDrm
    
    Increments the reference count. When the caller no longer needs to use the instance, it must call ExoMediaDrm.release() to decrement the reference count.
    A new instance will have an initial reference count of 1, and therefore it is not normally necessary for application code to call this method.
    
    Specified by:
    
    acquire in interface ExoMediaDrm
  - release
```
public void release()
```
    Description copied from interface: ExoMediaDrm
    
    Decrements the reference count. If the reference count drops to 0 underlying resources are released, and the instance cannot be re-used.
    
    Specified by:
    
    release in interface ExoMediaDrm
