The old dispatch mechanism has been left in place and continues to
be used by default for now. To enable native input dispatch,
edit the ENABLE_NATIVE_DISPATCH constant in WindowManagerPolicy.
Includes part of the new input event NDK API. Some details TBD.
To wire up input dispatch, as the ViewRoot adds a window to the
window session it receives an InputChannel object as an output
argument. The InputChannel encapsulates the file descriptors for a
shared memory region and two pipe end-points. The ViewRoot then
provides the InputChannel to the InputQueue. Behind the
scenes, InputQueue simply attaches handlers to the native PollLoop object
that underlies the MessageQueue. This way MessageQueue doesn't need
to know anything about input dispatch per-se, it just exposes (in native
code) a PollLoop that other components can use to monitor file descriptor
state changes.
There can be zero or more targets for any given input event. Each
input target is specified by its input channel and some parameters
including flags, an X/Y coordinate offset, and the dispatch timeout.
An input target can request either synchronous dispatch (for foreground apps)
or asynchronous dispatch (fire-and-forget for wallpapers and "outside"
targets). Currently, finding the appropriate input targets for an event
requires a call back into the WindowManagerServer from native code.
In the future this will be refactored to avoid most of these callbacks
except as required to handle pending focus transitions.
End-to-end event dispatch mostly works!
To do: event injection, rate limiting, ANRs, testing, optimization, etc.

Fix 2737842: Disable KeguardManager API if device policy is enabled
This change adds notification to find out when the device policy
has changed. When an admin adds or changes a policy, we get notified
and reset the state of keyguard to be enabled.
It also moves disabling keyguard into the TokenWatcher.acquired()
method to avoid disabling keyguard when a policy doesn't permit it.
This avoids reference counting issues in TokenWatcher and hence relieves
the ordering issue.
There is one remaining caveat. An application that uses KeyguardManager
to disable keyguard will need to disable keyguard again after any
policy change.
Tested:
Install and run app that disables keyguard with no admin. Result: keyguard is enabled/disabled as expected.
Enable admin and set quality = "something" after installing & running app. Result: keyguard is enabled.
Change admin password quality to "unspecified" and re-run app (per caveat). Result: keyguard is disabled.
Change admin password quality to "something" again. Result: keyguard is enabled.
Disable admin : Result: keyguard is enabled until app runs again (per caveat).
Added minor cosmetic changes after review.

Newly created dim surface has alpha set to 1 (opaque),

When new dim surface is created and expected dim value is calculated to 0
then alpha is never set making screen black (dut to default aplha=1)

Fix issue #2420340: if FLAG_SHOW_WHEN_LOCKED, do not show keyguard...
...go directly to unlock screen
Fix a problem where, when we are moving windows due to a configuration
change, our wait to have the windows get redrawn would also
inadvertently make us think their surfaces should be hidden, leading
to nasty things like the lock screen thinking it should be shown
again (and thus forcing the orientation back to portrait).

The problem turns out to have been a deep weirdness in the way that keyguard
and incall interact. Incall gets relaunched when the keyboard is opened/closed,
which transiently exposes keyguard with its nosensor orientation demands, and
that plus the long keyguard-hide animation was leaving incall in a bad state
from which the window manager didn't try to recover.
We now disregard animating-towards-hidden windows [i.e. keyguard] when running
through the app tokens to determine what orientation should be, and do not do
configuration calculations at all while the display is frozen. There can still
be a transient state in which incall is drawn in landscape, but things proceed
from there to relaunch it back into the proper portrait orientation, and it
ends up in the right state in the end.

Also a little tweak to the activity manager to behave better when

WindowManagerService (WMS) can wrongly report windows visibility due
to wrong handling of "starting windows".
"Starting windows" are special temporary windows that are displayed
while the application is starting.
Sometimes "starting windows" are considered when checking visibility
what leads to not reported or wrongly reported visibility status.
If visibility is not reported correctly some internal flows are
not executed and WMS internal state can be wrong.
PackageManager invokes this call back when its done handling
the media status update.

Well, mostly. There is still a problem here where the first time
you show the lock screen it just doesn't draw itself. I assume
this is something breaking in the view hierarchy as it floounders
around removing and adding new views as it is first being shown...
but no idea at this point what is the actual case.

Fix issue #2493497: Stuck in the Emergency dialer - Home/Back keys doesn't work
This was another case of not updating the window focus when needed, this time
when the lock screen was hidden.
Also re-arrange the layout/animate flow to address issues where you would see
a flicker of whatever was behind the lock screen when showing a new activity that
hides the lock screen. This was because we were deciding to hide the lock screen
during the layout phase, which meant we had to do it without considering whether
it had drawn. So we could hide the lock screen before the window is shown for the
first time after being drawn. Now we can do this in the policy during animate, so
we can wait until the window is drawn and actually being shown.
The flow in perform layout is thus significantly changed, where the layout and
animate loops are both under the same repeating loop. The actual flow from this
should be the same, but it now allows the policy to request a new layout after
the animation loop is done. This actually cleans up a number of things in this
code as the complexity has increased.
Finally this includes a change to the ui mode manager when switching modes, to do
the resource configuration switch at a different time. This makes transitions
between modes much cleaner (though not yet perfect).

bug #2479958: Investigate source of "Resources don't contain package
for resource number 0x7f0a0000"
Um, okay, so it turns out there were bugs all over the place where
we would load an XML resource from a another application, but not
use the Resources for that application to retrieve its resources...!
I think the only reason any of this stuff was working at all was
because it typically only cared about retrieving the resource
identifiers of the items (it would look up the values later).
Bug #2401082: Passion ERE26 monkey crash - InputMethodManagerService
Add some null checks.
We now only consider a device to be a default keyboard if its name
has "-keypad". A hack, but whatever.
Also add some debug logging for the input state to help identify such
issues in the future.
This is a bunch of reworking of how configuration changes are handled:
- When orientation is changing (for whatever reason), the window manager no
longer tries to pre-emptively compute a new configuration. Instead, it
just determines change is happening and tells the window manager.
- The activity manager is now responsible for giving the window manager the
final configuration it is using. This is both so it knows whem the
activity manager is done with its configuration updates, and so the window
manager can use the "real" configuration.
- When an orientation or other configuration change is happening, freeze the
screen and keep it frozen until the activity manager has given us the
final configuration.
- The window manager can now send new configurations to its clients during
its layout pass, as part of a resize, if it has determined that it has
changed. This allows for a new View.onConfigurationChanged() API for any
view to easily find out when the configuration has changed.
- ViewRoot now also works with the activity thread to make sure the process's
current resources are updated to the new configuration when it receives one
from a window. This ensures that at the time onConfigurationChanged() and
other view callbacks are happening, the correct configuration is in force.
- There is now a sequence number associated with Configuration, which
ActivityThread uses to avoid using stale configurations. This is needed now
that it can receive configurations asynchronously from both the window
manager and activity manager.
- The hack for keeping the locale has been removed, and underlying problem
fixed by having Configuration initialize its locale to "unknown" instead of
a valid default value.
Force the event-target bookkeeping to reset when an app explicitly
acknowledges event receipt. Furthermore, notify the event dispatcher
whenever a new window is created, even if there is nominally an
existing event target window.
These changes in tandem address a subtle race bug in which the event
dispatcher believes that there is an event recipient that it is still
waiting for even when the event in question has been acknowledged;
this results in a spurious ANR. There were checks in the existing code
that wound up doing the right thing in the case of windows becoming
hidden, but the case of non-fullscreen activities floating over them
[unavailable for input but still visible] exposed the race condition.
