This change makes touch ripples appear correctly on the action buttons
on media notifications. This involves the following changes:
- NotificationViewWrapper.onReinflated() sets the notification content
root's background to transparent rather than null when transferring the
background color to the NotificationBackgroundView. This gives the
ripples a surface to draw on.
- The RemoteViews for the media templates are changed to use a fixed
set of buttons instead of removing and re-adding them on every update.
This prevents the update caused by whatever action the tap invokes from
interrupting the ripples.
- A method is added to RemoteViews allowing the ripple color to be
specified. This allows us to change the ripple color to match the
foreground color of the controls, which is necessary for the ripples to
show up against a dark background.

A new API for setting the Private DNS settings value programatically via
the DevicePolicyManager.
Since there are two separate settings for Private DNS, and the value
provided for the hostname needs to be validated, a new
DevicePolicyManager API is introduced.
Only a Device Policy Client in Device Owner mode may change these
settings.
The DPC may additionally set a user restriction (added in a separate CL)
to prevent the user from changing Private DNS settings.

InputMethodManager has been a per-process singleton object. In order
to support behavior changes for multi-display support in Android Q,
however, InputMethodManager now needs to be per-display objects.
With this CL, context.getSystemService(InputMethodManager.class) will
start returning per-display InputMethodManager (IMM) instance.
Why?
There are two major reasons.
1. To support per-display focused window.
2. To support more simplified API for multi-session IME.
Currently per-process InputMethodManager instance directly receives
callback from ViewRootImpl upon windowFocusChanged, then it keeps
track of which Window is focused by storing its root view into
InputMethodManager#mCurRootView.
This design assumes that (within the same process) at most one Window
can have window focus, which is no longer true once we start
supporting per-display focused window (Bug 111361570).
Why we need to do this to support per-display focused window:
For traditional non multi-session IME cases (e.g. apps that use
Virtual Display APIs on phones), internal state of IMM can be easily
messed up once the system starts sending per-display
windowFocusChanged events to the same process, because IMM still
doesn't know that now each display has focused window. It is hard to
precisely predict what kind of issues we would see simply because such
a use case is most likely not expected in the original design.
Why we need to do this for multi-session IME:
For multi-session IME scenarios, in addition to the above concern in
InputMethodManager, the current design allows at most one IME session
per process. This means that if a process X is showing Activities to 3
different displays, only one Activity can interact with the
multi-session IME at the same time. If we do not change the current
design, the only way to work around is to ask app developers to
explicitly use different processes for each Activity, which may
require a lot of work (e.g. SharedPreference is not optimized for
multi-process use cases). This would also make multi-session IME
development complicated because the IME cannot know on which display
the IME is interacting until startInputOrWindowGainedFocus() is
actually called, and needs to do all the preparation and cleanup tasks
whenever startInputOrWindowGainedFocus() is called for a different
display than it's currently interacting with.
Alternative solutions considered:
Another possible approach is to update InputMethodManager singleton to
be able to maintain multiple mCurRootView and mServedView for each
display. This approach was abandoned because those fields and methods
are already marked as @UnsupportedAppUsage. I concluded that touching
@UnsupportedAppUsage things would have bigger compatibility risks than
per-display instance model.
Implementation note:
* Public APIs in IMM that take View instance as the first parameter
will verify whether the given View and IMM are associated with the
same display ID or not. If there is a display ID mismatch, such an
API call will be automatically forwarded to the correct IMM instance
IMM with a clear warning in logcat which tells that app developers
should use the correct IMM instance to avoid unnecessary performance
overhead.
* As a general rule, system server process cannot trust display ID
reported from applications. In order to enable IMMS to verify the
reported display ID, this CL also exposes display ID verification
logic from WMS to other system components via WindowManagerInternal.
* isInputMethodClientFocus() in WindowManagerService (WMS) is updated
to use top-focused-display to determine whether a given IME client
has IME focus or not. This is now necessary because with a recent
change [1] each display can have focused window. The previous logic
to check all the displays that belong to the given pid/uid [2] no
longer makes sense.
* Currently per-display InputMethodManager instances will not be
garbage collected because InputMethodManager#sInstanceMap keeps
holding strong references to them. Freeing those instances is
technically possible, but we need to be careful because multiple
processes (app, system, IME) are involved and at least system
process has a strict verification logic that lets the calling
process crash with SecurityException. We need to carefully
implement such a cleanup logic to avoid random process crash due to
race condition. Bug 116699479 will take care of this task.
Also to make sure that the performance regression (Bug 117434607) we
observed after my initial attempt [3] no longer exists, here are the
benchmark results with and without this CL.

ContextImpl has an internal rule that when ContextImpl#mDisplay is
null the Context is associated with the default display. The problem
is that, as discussed in Bug 117709581, when ContextImpl#mDisplay is
null ContextImpl#getDisplay() tries to get some non-null Display
object by making an IPC to the system server, which is redundant when
the display ID is the only thing that the caller wants to know.
By having an @hide method Context.getDisplayId(), we can ensure that
display ID can be obtained without any IPC. This enables us to
re-submit my CL [1] that aimed to instantiate InputMethodManager (IMM)
for each display but then got reverted due to a performance regression
(Bug 117434607).
There should be no developer-observable behavior change.
