This change moves the default logic into the actual Player
implementations, but does not introduce any behavior changes compared
to addMediaItems+removeMediaItems except to make the updates "atomic"
in ExoPlayerImpl, SimpleBasePlayer and MediaController. It also
provides backwards compatbility for cases where Players don't support
the operation.

This is a follow-up to 99dac0be0f where we made the same change in
ExoPlayerImpl and SimpleBasePlayer, but for consistency it makes
sense to also update the masking code in MediaControllerImplBase to
assume the same logic.
Note: MediaControllerImplLegacy already handles this case via
setMediaItems and doesn't need to be updated further.

MediaControllerImplBase currently drops the pending initial seek
position when a user sets an empty playlist.
When seeking in empty playlists and setting new empty playlists,
the class also drops the the period index (and wrongly assigns zero
instead of the windowIndex).

In terms of MCVR with a `VideoRendererEventListener`, the video size is set to
0/0 right after `onVideoDisabled()` is called and is set to the actual size as
soon as the video size is known after 'onVideoEnabled()`.
For ExoPlayer and in terms of the `Player` interface, `Player.getVideoSize()`
returns a video size of 0/0 when `Player.getCurrentTracks()` does not support
`C.TRACK_TYPE_VIDEO`. This is ensured by the masking behavior of
`ExoPlayerImpl` that sets an empty track selection result when the playing
period changes due to a seek or timeline removal.
When transitioning playback from a video media item to the next, or when
seeking within the same video media item, the renderer is not disabled.

This is a pre-requisite for the Android Studio upgrade assistant to

The periodic updates are only meant to happen while we are in the
same period or ad. This was already guaranteed except for two cases:
1. The Player in a session has updated its state without yet calling
its listeners
2. The session scheduled a PlayerInfo update that hasn't been sent yet
... and in both cases, the following happened:
- The change updated the mediaItemIndex to an index that didn't exist
in a previous Timeline known to the Controller
- One of the period position updates happened to be sent at exactly
this time
This problem can be avoided by only scheduling the update if we are
still in the same period/ad and haven't scheduled a normal PlayerInfo
update already.
Since new MediaControllers may still connect to old sessons with this
bug, we need an equivalent change on the controller side to ignore such
buggy updates.

When a `MediaButtonReceiver` is found in the manifest, the library
can implement the contract of SystemUI to signal that the app wants
a playback resumption notification to be displayed.
And, vice versa, if no `MediaButtonReceiver` is in the manifest, the
library will signal to not show the notification after the app has been
terminated.

The session activity is already sent to the controller with the
`ConnectionState` when it connects. This change adds the ability to update the
activity.
This allows an app to change the intent that is used to open an activity
for the notification. An app is likely to want to change the session activity
just before the session is released. This allows to use a different activity or
more importantly the back stack of the activity for while the app is running
and when used for the playback resumption notification.

The media button has API support with
`Callback.getPlaybackResumption()` that apps need to override to provide
a playlist to resume playback with.

This is a helper method that can used to obtain information about
the controller that is currently calling a Player method.

This simplifies the addition of new fields in the future.
Also do some misc clean up for the volume limit values:
- Add some documentation to mention assumed defaults
- Add the IntRange annotations to match the ones we have in Player
already
- Mention the limits in the relevant Player methods
- Avoid bundling default values
- Improve range checks for masking in MediaController

This is a bug currently, where commands are created once but never
updated again if the actions in MediaSessionCompat are changed.
PiperOrigin-RevId: 525999084
This check was a leftover from when the metadata was generated from
the MediaItem only. Since we moved to the actual MediaMetadata fields,
the check is completely unnecessary and prevents accessing metadata
when the GET_CURRENT_MEDIA_ITEM command is not available.
#minor-release
PiperOrigin-RevId: 524837587
The overrides specified by a MediaController may not use the exact
same TrackGroup instances as known to the Player because the groups
have been bundled to and from the controller. This bundling may
alter the instance slightly depending on the version used on each
side of the communication and the fields set (e.g. Format.metadata
is not supported for bundling).
This issue can be solved by creating unique track group ids for
each group on the session side before bundling. On the way back,
the groups in the track selection parameters can be mapped backed
to their original instances based on this id.

Previously, ExoPlayerImpl had volume flags hardcoded to SHOW_UI, but now the developer can choose what happens on volume change. The old methods have been deprecated.

The setter command is only used for setPlaylistMetadata and can
be named COMMAND_SET_PLAYLIST_METADATA. The getter commnad is
used to access getMediaMetadata and getPlaylistMetadata and can
be better named COMMAND_GET_METADATA to reflect this usage.

If the duration is reported in MediaMetadataCompat, it should
also be set in the QueueTimeline to match controller.getDuration()
PiperOrigin-RevId: 522022953
MediaItems are not meant to be unique in a playlist. If a legacy
session publishes multiple items that get converted to equal MediaItems,
the current code fails because we look up queue ids in a Map (that
doesn't allow duplicate entries).
Fix this by storing a simple list of items with additional data.

This wasn't added so far because releasing is always allowed from a
MediaController (as it just releases the connection, not the session
player). But Player instances can be created for other purposes and
the receiver of a Player instance should not always be allowed to
call release if it doesn't own the player resource.

This change includes 3 things:
- when the legacy media session is created, FLAG_HANDLES_QUEUE_COMMANDS
is advertised if the player has the COMMAND_CHANGE_MEDIA_ITEMS
available.
- when the player changes its available commands, a new
PlaybackStateCompat is sent to the remote media controller to
advertise the updated PlyabackStateCompat actions.
- when the player changes its available commands, the legacy media
session flags are sent accoridingly: FLAG_HANDLES_QUEUE_COMMANDS is
set only if the COMMAND_CHANGE_MEDIA_ITEMS is available.

This change fixes an issue that can be reproduced when
a controller `onConnect` creates a `QueueTimeline` out
of the state of a legacy session and then `prepare` is called.
`activeQueueItemId`, `metadata` and the `queue` of the legacy
session are used when a `QueueTimeline` is created. The change
adds unit tests to cover the different combinatoric cases these
properties being set or unset.
PiperOrigin-RevId: 505731288
Added onSetMediaItems callback listener to allow the session to modify/set MediaItem list, starting index and position before call to Player.setMediaItem(s).
Added conditional check in MediaSessionStub.setMediaItem methods to only call player.setMediaItem rather than setMediaItems if player does not support COMMAND_CHANGE_MEDIA_ITEMS

We stop estimating new position when pausing until we
receive a new position from the player. However, this
means that we will continue to return a possible stale
previous position. Updating the current position before
pausing solves this issue.
PiperOrigin-RevId: 503153982
We currently only document it for the getCurrentMediaItem(), but
the command was always meant to cover all information about the
current media item and the position therein.
To correctly hide information for controllers, we need to filter
the Timeline when bundling the PlayerInfo class if only this
command is available.

The migration strategy is to deprecate `androidx.media3.session.BitmapLoader` and copy the file into common since BitmapLoader is a public interface that apps could be relying on.

The period updates were introduced to ensure the buffered position is
updated regularly and that any playback position drift is corrected.
None of these updates need to happen while the player is paused or
not loading and we can avoid the constant binder interactions.

Some Player methods operate relative to existing indices in the
playlist (add,remove,move,seek). As these operations may be issued
from a place with a stale playlist (e.g. a controller that sends
a command while the playlist is changing), we have to handle out-
of-bounds indices gracefully. In most cases this is already
documented and implemented correctly. However, some cases are not
documented and the existing player implementations don't handle
these cases consistently (or in some cases not even correctly).
PiperOrigin-RevId: 495856295
Some Player methods like getting the Looper and adding listeners
were always allowed to be called from any thread, but this is
undocumented. This change makes the threading rules of these
methods more explicit.
Removing listeners was never meant to be called from another thread
and we also don't support it safely because final callbacks may
be triggered from the wrong thread. To find potential issues, we
can assert the correct thread when releasing listeners.
Finally, there is a potential race condition when calling addListener
from a different thread at the same time as release, which may lead to
a registered listener that could receive callbacks after the player is
released.

The folder type has a mix of information about the item. It shows
whether the item is browsable (type != FOLDER_TYPE_NONE) and
which Bluetooth folder type to set for legacy session information.
It's a lot clearer to split this into a boolean isBrowsable and
use the existing mediaType to map back to the bluetooth folder type
where required.
folderType is not marked as deprecated yet as this would be an API
change, which will be done later.
PiperOrigin-RevId: 493544589
This allows legacy media controllers and browsers to access this
information and legacy sessions and browser services to set this
information.

This change includes a change in the `IMediaController.aidl` file and needs
to provide backwards compatibility for when a client connects that is of an older or
newer version of the current service implementation.
This CL proposes to create a new AIDL method `onPlayerInfoChangedWithExtensions`
that is easier to extend in the future because it does use an `Bundle` rather than
primitives. A `Bundle` can be changed in a backward/forwards compatible way
in case we need further changes.
The compatibility handling is provided in `MediaSessionStub` and `MediaControllerStub`. The approach is not based on specific AIDL/Binder features but implemented fully in application code.

The direct executor is not the proper way to determine on what thread to run the
`Future.Listener` and the `MediaControllerCreationListener` because the listener
may call the controller passed as argument which must happen on the same thread
that built the controller. This change makes sure this is the case.
PiperOrigin-RevId: 490478587
This avoids that apps have to depend on the legacy compat support
library when they want to make this conversion.
Also add a version to both helper methods that takes a Looper to
give apps the option to use an existing Looper, which should be
much faster than spinning up a new thread for every method call.

When receiving the `onTimelineChanged` callback, we convert the timeline to the list of `QueueItem`s, where decoding a bitmap is needed for building each of the `QueueItem`s. The strategy is similar to what we did in <unknown commit> for list of `MediaBrowserCompat.MediaItem` - set the queue item list until the bitmaps decoding for all the `MediaItem`s are completed.
