The assertion asserts against a `Period` and an `AdPlaybackState` which actually
asserts against a resolved ad which is what `ExoPlayerImplInternal` does later and
what gives us a `SEEK_ADJUSTMENT`. However, this assertion is not required at the
moment of masking, because we are sure that the resolved seek results in a content
period and never an ad period.

We create an empty CueGroup in many places as default or
where none is needed. Instead, we can define a constant
for this purpose and reuse it.

When the player finishes playback and reaches the STATE_ENDED,
the notification remains visible with a pause button and the
service is kept in the foreground. This is a bug.
With this change, when the player reaches the STATE_ENDED, the
service is stopped from the foreground and a notification is shown
with a play button. If the play icon is tapped, the player will restart
playback of the last played item. Playing the last played item again
is the existing behavior when play/pause commands are received from
the legacy MediaSession (e.g. BT headset buttons).

Once a controller bound to a MediaSessionService unbinds, this service
may be destroyed immediately if this was the last bound controller and
the service isn't started in the foreground.
At the time of releasing the controller, there may still be pending
commands that need to be handled by the session service. These commands
may cause the session service to post a foreground notification to
keep it alive. So to avoid the destruction of the service while these
commands are still handled, we need to keep the controller bound.
We also add a timeout in case the session tasks are never completed
by the session implementation. In case the controller is destroyed,
the unbinding happens automatically by the system.

The DefaultMediaNotificationProvider caches the last loaded artwork
bitmap so that the bitmap isn't loaded again when the notification is
updated, e.g., the player is transiting from playing to paused. However,
loading bitmap requests for bitmaps that are already being loaded are
not suppressed. For example, if the notification is updated while the
artwork is still downloading, the same artwork might be downloaded
multiple times.
This change suppresses a bitmap load request if the same artwork is
still being loaded, to avoid additional artwork downloads.

We currently clear all pending messages, including the one that flushes
pending commands to the MediaSession. To ensure all commands that have
been called before controller.release() are still sent, we can manually
trigger the flush message from the release call.
Related to handling the final flush because disconnecting the controller,
MediaSessionStub didn't post the removal of the controller to the
session thread, creating a race condition between removing the controller
and actually handling the flush.

These constructors are currently very intertwined, passing `this`
references from the constructor of one to the constructor of another
before the first constructor is complete (and so the `this` reference
isn't really valid yet).
This change uses checker framework `@UnderInitialization` and
`@NotOnlyInitialized` annotations to make it more clear that the
references are not available yet. For the one 'direct' access needed
in the second constructor (calling `getApplicationLooper()`) we now
pass the `applicationLooper` directly alongside (to avoid needing to
dereference the reference 'too early').
This change also ensures that where a class hierarchy has a
'dependent' class hierarchy, the 'subclass' instance is always used
(by both subclass and superclass) without casting or manually hiding
the superclass field, by defining an overridable `getFoo()` method
instead and always using it.

"seq" is not a well-defined abbreviation and the value is

Add a Builder to constructor DefaultMediaNotificationProvider. The
Builder can also set the provider's:
- notification ID
- notification channel ID
- notification channel name
The change adds an API for apps to set the small icon in notifications.

Some commands are run asynchronously and subsequent commands need
to wait until the previous one finished. This can be supported
by returning a Future for each command and using the existing
command execution logic to wait for each Future to complete.
As some MediaSessionStub code is now executed delayed to when it
was originally created, we also need to check if the session is
not released before triggering any actions or sending result codes.

The commands currently use a task and a postTask that are chained
together manually. In some cases, e.g. when adding MediaItems,
the postTask is already a chain of commands in itself.
To allow using the entire command handling as a single task
(for simplified queueing), we can change the implementation to
always create a single task. If multiple subtasks need to be
chained together, we can do that by wrapping the method calls.
In case a task is asynchronous, we can also use Futures to
chain them together.
Overall, this is just a refactoring and changes no logic.

Some commands may be asynchronous and subsequent commands need to
wait for them to complete before running. This change updates the
queue to use (and listen to) Futures instead of calling Runnables
directly. The commands are currently still added as Runanbles
though, so this change is a no-op.
Also moves the permission check in MediaSessionImpl to before
queueing the command because the permission should be check at
the time of calling the method.
When executing the comamnds in the queue, we need to be careful
to avoid recursion in the same thread (which happens when both
the Future is immediate and running on the correct thread already).
To avoid recursion, we detect this case and loop the commands
instead.

After this change the current tracks are sent to the controller as part of

These calls were not implemented so far as they require a mix of
initial prepareFrom/playFrom calls and addQueueItem. We can also
support clients without queue handling to set single MediaItems.
To make the calls consistent and predictable in the session,
we need to ensure that none of the play/pause/addQueueItem/
removeQueueItem/prepare/playFromXYZ/prepareFromXYZ are called
before the controller is prepared and has media.

The service handles three different types of `Intents`. Custom command and media
command Intents created by the library and media button event Intents from other
sources.
Media commands from the library as well as from external sources have the action
set to `android.intent.action.MEDIA_BUTTON`. If the data URI is set and can be
used to identify a session then it is a library Intent. If the Intent is coming
from an external KeyEvent, the service implementation is asked which session to use
by calling `onGetSession(controllerInfo)` with the controller info being an
anonymous legacy controller info.
Intents representing a custom command are always coming from the library and hence
always have a data URI.

Some Player implementations have no playlist capability but can still
set a MediaItem for playback. Examples are a MediaController connected
to a legacy MediaSession, ExoPlayer up to 2.12 or MediaPlayer.
To indicate this capability, we need an allowed command in addition
to COMMAND_CHANGE_MEDIA_ITEMS that just allows to set a single item
that replaces everything that is currently played.
