Public methods

addOnActiveSessionsChangedListener

public void addOnActiveSessionsChangedListener (MediaSessionManager.OnActiveSessionsChangedListener sessionListener, 
                ComponentName notificationListener)

Add a listener to be notified when the list of active sessions changes.This requires the android.Manifest.permission.MEDIA_CONTENT_CONTROL permission be held by the calling app. You may also retrieve this list if your app is an enabled notification listener using the NotificationListenerService APIs, in which case you must pass the ComponentName of your enabled listener. Updates will be posted to the thread that registered the listener.

Parameters
`sessionListener`	`MediaSessionManager.OnActiveSessionsChangedListener`: The listener to add. This value cannot be `null`.
`notificationListener`	`ComponentName`: The enabled notification listener component. May be null. This value may be `null`.

addOnActiveSessionsChangedListener

public void addOnActiveSessionsChangedListener (MediaSessionManager.OnActiveSessionsChangedListener sessionListener, 
                ComponentName notificationListener, 
                Handler handler)

Parameters
`sessionListener`	`MediaSessionManager.OnActiveSessionsChangedListener`: The listener to add. This value cannot be `null`.
`notificationListener`	`ComponentName`: The enabled notification listener component. May be null. This value may be `null`.
`handler`	`Handler`: The handler to post events to. This value may be `null`.

addOnSession2TokensChangedListener

public void addOnSession2TokensChangedListener (MediaSessionManager.OnSession2TokensChangedListener listener)

This API is not generally intended for third party application developers. Use the AndroidX Media2 session Library for consistent behavior across all devices.

Adds a listener to be notified when the getSession2Tokens() changes.

Parameters
`listener`	`MediaSessionManager.OnSession2TokensChangedListener`: The listener to add This value cannot be `null`.

addOnSession2TokensChangedListener

public void addOnSession2TokensChangedListener (MediaSessionManager.OnSession2TokensChangedListener listener, 
                Handler handler)

This API is not generally intended for third party application developers. Use the AndroidX Media2 session Library for consistent behavior across all devices.

Adds a listener to be notified when the getSession2Tokens() changes.

Parameters
`listener`	`MediaSessionManager.OnSession2TokensChangedListener`: The listener to add This value cannot be `null`.
`handler`	`Handler`: The handler to call listener on. This value cannot be `null`.

getActiveSessions

public List<MediaController> getActiveSessions (ComponentName notificationListener)

Get a list of controllers for all ongoing sessions. The controllers will be provided in priority order with the most important controller at index 0.

This requires the android.Manifest.permission.MEDIA_CONTENT_CONTROL permission be held by the calling app. You may also retrieve this list if your app is an enabled notification listener using the NotificationListenerService APIs, in which case you must pass the ComponentName of your enabled listener.

Parameters
`notificationListener`	`ComponentName`: The enabled notification listener component. May be null. This value may be `null`.

Returns
`List<MediaController>`	A list of controllers for ongoing sessions.

getSession2Tokens

public List<Session2Token> getSession2Tokens ()

This API is not generally intended for third party application developers. Use the AndroidX Media2 session Library for consistent behavior across all devices.

Gets a list of Session2Token with type Session2Token#TYPE_SESSION for the current user.

Although this API can be used without any restriction, each session owners can accept or reject your uses of MediaSession2.

Returns
`List<Session2Token>`	A list of `Session2Token`. This value cannot be `null`.

isTrustedForMediaControl

public boolean isTrustedForMediaControl (MediaSessionManager.RemoteUserInfo userInfo)

Checks whether the remote user is a trusted app.

An app is trusted if the app holds the android.Manifest.permission.MEDIA_CONTENT_CONTROL permission or has an enabled notification listener.

Parameters
`userInfo`	`MediaSessionManager.RemoteUserInfo`: The remote user info from either `MediaSession#getCurrentControllerInfo()` or `MediaBrowserService#getCurrentBrowserInfo()`. This value cannot be `null`.

Returns
`boolean`	`true` if the remote user is trusted and its package name matches with the UID. `false` otherwise.

notifySession2Created

public void notifySession2Created (Session2Token token)

This API is not generally intended for third party application developers. Use the AndroidX Media2 session Library for consistent behavior across all devices.

Notifies that a new MediaSession2 with type Session2Token#TYPE_SESSION is created.

Do not use this API directly, but create a new instance through the MediaSession2.Builder instead.

Parameters
`token`	`Session2Token`: newly created session2 token This value cannot be `null`.

removeOnActiveSessionsChangedListener

public void removeOnActiveSessionsChangedListener (MediaSessionManager.OnActiveSessionsChangedListener listener)

Stop receiving active sessions updates on the specified listener.

Parameters
`listener`	`MediaSessionManager.OnActiveSessionsChangedListener`: The listener to remove. This value cannot be `null`.

removeOnSession2TokensChangedListener

public void removeOnSession2TokensChangedListener (MediaSessionManager.OnSession2TokensChangedListener listener)

This API is not generally intended for third party application developers. Use the AndroidX Media2 session Library for consistent behavior across all devices.

Removes the OnSession2TokensChangedListener to stop receiving session token updates.

Parameters
`listener`	`MediaSessionManager.OnSession2TokensChangedListener`: The listener to remove. This value cannot be `null`.
