Public constructors

DrmManagerClient

Added in API level 11

Public methods

acquireDrmInfo

Added in API level 11
DrmInfo acquireDrmInfo (DrmInfoRequest drmInfoRequest)

Retrieves information for registering, unregistering, or acquiring rights.

acquireRights

Added in API level 11
int acquireRights (DrmInfoRequest drmInfoRequest)

Returns
int ERROR_NONE for success; ERROR_UNKNOWN for failure.

canHandle

close

Added in API level 24
void close ()

Releases resources associated with the current session of DrmManagerClient. It is considered good practice to call this method when the DrmManagerClient object is no longer needed in your application. After this method is called, DrmManagerClient is no longer usable since it has lost all of its required resource.

closeConvertSession

Added in API level 11
DrmConvertedStatus closeConvertSession (int convertId)

Informs the DRM plug-in (agent) that there is no more data to convert or that an error has occurred. Upon successful conversion of the data, the DRM agent will provide an offset value indicating where the header and body signature should be added. Appending the signature is necessary to protect the integrity of the converted file.

Parameters
convertId int: Handle for the conversion session.
Returns
DrmConvertedStatus A DrmConvertedStatus object that contains the status of the data conversion, the converted data, and the offset for the header and body signature.

convertData

Added in API level 11
DrmConvertedStatus convertData (int convertId, 
                byte[] inputData)

Converts the input data (content) that is part of a rights-protected file. The converted data and status is returned in a DrmConvertedStatus object. This method should be called each time there is a new block of data received by the application.

Parameters
convertId int: Handle for the conversion session.
inputData byte: Input data that needs to be converted.
Returns
DrmConvertedStatus A DrmConvertedStatus object that contains the status of the data conversion, the converted data, and offset for the header and body signature. An application can ignore the offset because it is only relevant to the closeConvertSession() method.

Protected methods

finalize

Added in API level 11
void finalize ()

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. A subclass overrides the finalize method to dispose of system resources or to perform other cleanup.

The general contract of finalize is that it is invoked if and when the JavaTM virtual machine has determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, except as a result of an action taken by the finalization of some other object or class which is ready to be finalized. The finalize method may take any action, including making this object available again to other threads; the usual purpose of finalize, however, is to perform cleanup actions before the object is irrevocably discarded. For example, the finalize method for an object that represents an input/output connection might perform explicit I/O transactions to break the connection before the object is permanently discarded.

The finalize method of class Object performs no special action; it simply returns normally. Subclasses of Object may override this definition.

The Java programming language does not guarantee which thread will invoke the finalize method for any given object. It is guaranteed, however, that the thread that invokes finalize will not be holding any user-visible synchronization locks when finalize is invoked. If an uncaught exception is thrown by the finalize method, the exception is ignored and finalization of that object terminates.

After the finalize method has been invoked for an object, no further action is taken until the Java virtual machine has again determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, including possible actions by other objects or classes which are ready to be finalized, at which point the object may be discarded.

The finalize method is never invoked more than once by a Java virtual machine for any given object.

Any exception thrown by the finalize method causes the finalization of this object to be halted, but is otherwise ignored.

Throws
Throwable

Hooray!
