DrmManagerClient

Indicates that a request was successful or that no error occurred.

Indicates that an error occurred and the reason is not known.

Creates a DrmManagerClient.

Retrieves information for registering, unregistering, or acquiring rights.

Processes a given DrmInfoRequest and returns the rights information asynchronously.

This is a utility method that consists of an acquireDrmInfo() and a processDrmInfo() method call. This utility method can be used only if the selected DRM plug-in (agent) supports this sequence of calls. Some DRM agents, such as OMA, do not support this utility method, in which case an application must invoke acquireDrmInfo() and processDrmInfo() separately.

Checks whether the given MIME type or URI can be handled.

Checks whether the given MIME type or path can be handled.

Checks whether the given content has valid rights.

Checks whether the given rights-protected content has valid rights for the specified DrmStore.Action.

Checks whether the given rights-protected content has valid rights for the specified DrmStore.Action.

Check whether the given content has valid rights.

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.

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.

Retrieves information about all the DRM plug-ins (agents) that are registered with the DRM framework.

Retrieves constraint information for rights-protected content.

Retrieves constraint information for rights-protected content.

Retrieves the type of rights-protected object (for example, content object, rights object, and so on) using the specified URI or MIME type. At least one parameter must be specified to retrieve the DRM object type.

Retrieves the type of rights-protected object (for example, content object, rights object, and so on) using the specified path or MIME type. At least one parameter must be specified to retrieve the DRM object type.

Retrieves metadata information for rights-protected content.

Retrieves metadata information for rights-protected content.

Retrieves the MIME type embedded in the original content.

Retrieves the MIME type embedded in the original content.

Initiates a new conversion session. An application must initiate a conversion session with this method each time it downloads a rights-protected file that needs to be converted.

This method applies only to forward-locking (copy protection) DRM schemes.

Processes the given DRM information based on the information type.

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 release() is called, DrmManagerClient is no longer usable since it has lost all of its required resource.

Removes all the rights information of every DRM plug-in (agent) associated with the DRM framework. Will be used during a master reset.

Removes the rights associated with the given rights-protected content.

Removes the rights associated with the given rights-protected content.

Saves rights to a specified path and associates that path with the content path.

Note: For OMA or WM-DRM, rightsPath and contentPath can be null.

Registers an DrmManagerClient.OnErrorListener callback, which is invoked when the DRM framework sends error information.

Registers an DrmManagerClient.OnEventListener callback, which is invoked when the DRM framework sends information about DRM processing.

Registers an DrmManagerClient.OnInfoListener callback, which is invoked when the DRM framework sends status or warning information during registration or rights acquisition.

Invoked when the garbage collector has detected that this instance is no longer reachable. The default implementation does nothing, but this method can be overridden to free resources.

Note that objects that override finalize are significantly more expensive than objects that don't. Finalizers may be run a long time after the object is no longer reachable, depending on memory pressure, so it's a bad idea to rely on them for cleanup. Note also that finalizers are run on a single VM-wide finalizer thread, so doing blocking work in a finalizer is a bad idea. A finalizer is usually only necessary for a class that has a native peer and needs to call a native method to destroy that peer. Even then, it's better to provide an explicit close method (and implement Closeable), and insist that callers manually dispose of instances. This works well for something like files, but less well for something like a BigInteger where typical calling code would have to deal with lots of temporaries. Unfortunately, code that creates lots of temporaries is the worst kind of code from the point of view of the single finalizer thread.

If you must use finalizers, consider at least providing your own ReferenceQueue and having your own thread process that queue.

Unlike constructors, finalizers are not automatically chained. You are responsible for calling super.finalize() yourself.

Uncaught exceptions thrown by finalizers are ignored and do not terminate the finalizer thread. See Effective Java Item 7, "Avoid finalizers" for more.
