When users open volume panel and keep on changing the volume slider for
a while, the panel starts to defer the slider updating, and finally gets
stuck and causes an ANR.
Root cause:
Volume panel has four volume adjusting slices. Each of them registers
a broadcast receiver to listen to the volume changed and muted events.
However, when the media volume changes, AudioManager will send four
broadcasts (music, assistant, accessibility, tts) to every receiver, and
each of them will reload slice four times. Thus, one media volume
changed event will lead to 16 (4*4) UI updates. Consequently, keeping on
sliding the volume bar will trigger hundreds of broadcasts and UI
updates, which makes the system busy and getting stuck.
Solution:
Introduce a VolumeSliceHelper to integrate the broadcasts of the volume
slices specifically.
1. Only register one broadcast receiver to reduce the broadcast loading
since the four slices are listening to the same signal.
2. Filter the only one eligible broadcast among the multiple concurrent
ones, and then relay it to the registered slice.
3. Listen to one more action STREAM_DEVICES_CHANGED_ACTION to update the
volume panel when audio output device changes.

Re-launching volume panel continuously will trigger an endless panel
loading, show a transparent unfinished UI, and then block the user's
screen.
Root cause:
When the activity receives a new intent from user's clicking, it will
call PanelFragment#createPanelContent to update the current fragment.
The method triggers an animation and then loads the panel content. If
multiple invocations run concurrently before the animation or the
loading finish, the loader's countdown latch will be increased
abnormally and lead to the endless loading.
Solution:
1. Since the invocations are in UI thread, simply add a flag to avoid
reentrance when the panel is animating or loading.
2. Filter out the same panel's creation request when the panel is still
visible.
3. Do not force a panel's recreation when it's under construction.

Root cause:
Sometimes loading contextual cards exceeds 1 second and a timeout
expires. In the past, we used the timeout in order not to update
homepage UI and to avoid screen scrolling. But we've introduced a
mechanism of card space pre-allocation to avoid flickering, so when the
timeout expires, the pre-allocated space will be always blank.
Solution:
Display a card on timeout if the one-card space is pre-allocated.
