## Public constructors

### DrmManagerClient

    public DrmManagerClient (Context context)

Creates a `DrmManagerClient`.

Parameters
`context` | `Context`: Context of the caller.

## Public methods

### acquireDrmInfo

    public DrmInfo acquireDrmInfo (DrmInfoRequest drmInfoRequest)

Retrieves information for registering, unregistering, or acquiring rights.

Parameters
`drmInfoRequest` | `DrmInfoRequest`: The `DrmInfoRequest` that specifies the type of DRM information being retrieved.

Returns
`DrmInfo` | A `DrmInfo` instance.

### acquireRights

    public int acquireRights (DrmInfoRequest drmInfoRequest)

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.

Parameters
`drmInfoRequest` | `DrmInfoRequest`: The `DrmInfoRequest` used to acquire the rights.

Returns
`int` | ERROR_NONE for success; ERROR_UNKNOWN for failure.

### canHandle

    public boolean canHandle (String path,
                    String mimeType)

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

Parameters
`path` | `String`: Path of the content to be handled.
`mimeType` | `String`: MIME type of the object to be handled.

Returns
`boolean` | True if the given MIME type or path can be handled; false if they cannot be handled.

### canHandle

    public boolean canHandle (Uri uri,
                    String mimeType)

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

Parameters
`uri` | `Uri`: URI for the content to be handled.
`mimeType` | `String`: MIME type of the object to be handled

Returns
`boolean` | True if the given MIME type or URI can be handled; false if they cannot be handled.

### checkRightsStatus

    public int checkRightsStatus (String path)

Checks whether the given content has valid rights.

Parameters
`path` | `String`: Path to the rights-protected content.

Returns
`int` | An `int` representing the `DrmStore.RightsStatus` of the content.

### checkRightsStatus

    public int checkRightsStatus (Uri uri)

Check whether the given content has valid rights.

Parameters
`uri` | `Uri`: URI of the rights-protected content.

Returns
`int` | An `int` representing the `DrmStore.RightsStatus` of the content.

### checkRightsStatus

    public int checkRightsStatus (String path,
                    int action)

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

Parameters
`path` | `String`: Path to the rights-protected content.
`action` | `int`: The `DrmStore.Action` to perform.

Returns
`int` | An `int` representing the `DrmStore.RightsStatus` of the content.

### checkRightsStatus

    public int checkRightsStatus (Uri uri,
                    int action)

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

Parameters
`uri` | `Uri`: URI for the rights-protected content.
`action` | `int`: The `DrmStore.Action` to perform.

Returns
`int` | An `int` representing the `DrmStore.RightsStatus` of the content.

### close

    public 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. This method was added in API 24. In API versions 16 through 23, release() should be called instead. There is no need to do anything for API versions prior to 16.

### closeConvertSession

    public 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

    public 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.

### getAvailableDrmEngines

Returns
`String[]` | A `String` array of DRM plug-in descriptions.

## Protected methods

### finalize

    protected 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 Java™ 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` |
