				↳	androidx.media2.session.MediaLibraryService

Base class for media library services, which is the service containing .

Media library services enable applications to browse media content provided by an application and ask the application to start playing it. They may also be used to control content that is already playing by way of a MediaSession.

When extending this class, also add the following to your AndroidManifest.xml.

<service android:name="component_name_of_your_implementation" >
  <intent-filter>
    <action android:name="androidx.media2.session.MediaLibraryService" />
  </intent-filter>
</service>

You may also declare

android.media.browse.MediaBrowserService

for compatibility with android.support.v4.media.MediaBrowserCompat. This service can handle it automatically.

Constants

SERVICE_INTERFACE

Added in 1.0.0

Deprecated in 1.3.0

const val SERVICE_INTERFACE = "androidx.media2.session.MediaLibraryService": String!

The Intent that must be declared as handled by the service.

Public constructors

MediaLibraryService

Added in 1.0.0

Deprecated in 1.3.0

MediaLibraryService()

Public functions

onBind

fun onBind(intent: Intent): IBinder!

Default implementation for MediaSessionService to handle incoming binding request. If the request is for getting the session, the intent will have action SERVICE_INTERFACE.

Override this method if this service also needs to handle binder requests other than SERVICE_INTERFACE. Derived classes MUST call through to the super class's implementation of this method.

Parameters
`intent: Intent`

Returns
`IBinder!`	Binder

onGetSession

Added in 1.3.0

Deprecated in 1.3.0

abstract fun onGetSession(controllerInfo: MediaSession.ControllerInfo): MediaLibraryService.MediaLibrarySession?

Called when a MediaController is created with the this service's SessionToken. Return the session for telling the controller which session to connect. Return null to reject the connection from this controller.

Session service automatically maintains the returned session. In other words, session returned here will be added here and removed when the session is closed. You don't need to manually call addSession nor removeSession.

There are two special cases where the getPackageName returns non-existent package name:

When the service is being started through the media button intent, the method will return ACTION_MEDIA_BUTTON. If you want to allow the service being started by the media button events, do not return null.
When the legacy android.media.browse.MediaBrowser or android.support.v4.media.MediaBrowserCompat tries to connect, the method will return SERVICE_INTERFACE. If you want to allow the service being bound by the legacy media browsers, do not return null.

For those special cases, the values returned by getUid and getConnectionHints have no meaning.

This method is always called on the main thread.

Parameters
`controllerInfo: MediaSession.ControllerInfo`	information of the controller which is trying to connect

Returns
`MediaLibraryService.MediaLibrarySession?`	a `MediaSession` instance for the controller to connect to, or `null` to reject connection
