class SessionToken

A token that represents an ongoing MediaSession or a service (, 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 or a MediaBrowser to communicate with the session.

It can also be obtained by getAllServiceTokens.

The Token or android.support.v4.media.session.MediaSessionCompat.Token.
Returns
ListenableFuture<SessionToken!>!

A ListenableFuture for the SessionToken.

createSessionToken

@UnstableApi
java-static fun createSessionToken(
    context: Context!,
    token: Parcelable!,
    completionLooper: Looper!
): ListenableFuture<SessionToken!>!

Creates a token from a Token or android.support.v4.media.session.MediaSessionCompat.Token.

fromBundle

@UnstableApi
java-static fun fromBundle(bundle: Bundle!): SessionToken!

getAllServiceTokens

java-static fun getAllServiceTokens(context: Context!): ImmutableSet<SessionToken!>!

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

The app targeting API level 30 or higher must include a <queries> element in their manifest to get service tokens of other apps. See the following example and this guide for more information. 

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