Constants

DEFAULT_PROVIDER

@UnstableApi
public static final ExoMediaDrm.Provider DEFAULT_PROVIDER

ExoMediaDrm.Provider that returns a new FrameworkMediaDrm for the requested UUID. Returns a DummyExoMediaDrm if the protection scheme identified by the given UUID is not supported by the device.

Public methods

acquire

@UnstableApi
synchronized public void acquire()

Increments the reference count. When the caller no longer needs to use the instance, it must call 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.

closeSession

@UnstableApi
public void closeSession(byte[] sessionId)

Closes a DRM session.

Parameters
`byte[] sessionId`	The ID of the session to close.

createCryptoConfig

@UnstableApi
public FrameworkCryptoConfig createCryptoConfig(byte[] sessionId)

Creates a CryptoConfig that can be passed to a compatible decoder to allow decryption of protected content using the specified session.

Parameters
`byte[] sessionId`	The ID of the session.

Returns
`FrameworkCryptoConfig`	A `CryptoConfig` for the given session.

Throws
`android.media.MediaCryptoException`	If a `CryptoConfig` could not be created.

getCryptoType

@UnstableApi
@C.CryptoType
public int getCryptoType()

Returns the type of CryptoConfig instances returned by createCryptoConfig.

getKeyRequest

@UnstableApi
public ExoMediaDrm.KeyRequest getKeyRequest(
    byte[] scope,
    @Nullable List<DrmInitData.SchemeData> schemeDatas,
    int keyType,
    @Nullable HashMap<String, String> optionalParameters
)

Generates a key request.

Parameters
`byte[] scope`	If `keyType` is `KEY_TYPE_STREAMING` or `KEY_TYPE_OFFLINE`, the ID of the session that the keys will be provided to. If `keyType` is `KEY_TYPE_RELEASE`, the `keySetId` of the keys to release.
`@Nullable List<DrmInitData.SchemeData> schemeDatas`	If key type is `KEY_TYPE_STREAMING` or `KEY_TYPE_OFFLINE`, a list of `SchemeData` instances extracted from the media. Null otherwise.
`int keyType`	The type of the request. Either `KEY_TYPE_STREAMING` to acquire keys for streaming, `KEY_TYPE_OFFLINE` to acquire keys for offline usage, or `KEY_TYPE_RELEASE` to release acquired keys. Releasing keys invalidates them for all sessions.
`@Nullable HashMap<String, String> optionalParameters`	Are included in the key request message to allow a client application to provide additional message parameters to the server. This may be `null` if no additional parameters are to be sent.

Returns
`ExoMediaDrm.KeyRequest`	The generated key request.

Throws
`android.media.NotProvisionedException`
