SessionToken

Artifact: androidx.media3:media3-session

Kotlin |Java

class SessionToken

A token that represents an ongoing MediaSession or a service (MediaSessionService, MediaLibraryService, or androix.media.MediaBrowserServiceCompat). If it represents a service, it may not be ongoing.

This may be passed to apps by the session owner to allow them to create a MediaController or a MediaBrowser to communicate with the session.

It can also be obtained by getAllServiceTokens.

Returns an ImmutableSet of session tokens for media session services; MediaSessionService, MediaLibraryService, and androidx.media.MediaBrowserServiceCompat regardless of their activeness.

<intent>
  <action android:name="androidx.media3.session.MediaSessionService" />
</intent>
<intent>
  <action android:name="androidx.media3.session.MediaLibraryService" />
</intent>
<intent>
  <action android:name="android.media.browse.MediaBrowserService" />
</intent>

getExtras

fun getExtras(): Bundle!

Returns the extra Bundle of this token.

getInterfaceVersion

@UnstableApi
fun getInterfaceVersion(): Int

Returns the interface version of the session or UNKNOWN_INTERFACE_VERSION.

getPackageName

fun getPackageName(): String!

Returns the package name of the session

getServiceName

fun getServiceName(): String!

Returns the service name of the session. It will be an empty string if the type is TYPE_SESSION.

getSessionVersion

fun getSessionVersion(): Int

Returns the library version of the session, UNKNOWN_SESSION_VERSION, or PLATFORM_SESSION_VERSION.

If the session is a platform android.media.session.MediaSession or legacy android.support.v4.media.session.MediaSessionCompat, this will be PLATFORM_SESSION_VERSION.
If the token's type is TYPE_SESSION, this will be the same as VERSION_INT of the session.
If the token's type is TYPE_SESSION_SERVICE or TYPE_LIBRARY_SERVICE, this will be UNKNOWN_SESSION_VERSION. You can obtain the actual session version after a connecting a controller via the connected token of type TYPE_SESSION.

getType

@SessionToken.TokenType
fun getType(): Int

Returns the type of this token. One of TYPE_SESSION, TYPE_SESSION_SERVICE, or TYPE_LIBRARY_SERVICE.

getUid

fun getUid(): Int
