Redesigned how ViewRootImpl delivers input events to views,
the IME and to native activities to fix several issues.
The prior change to make IME input event delegation use
InputChannels failed to take into account that InputMethodManager
is a singleton attached to the main looper whereas UI may be
attached to any looper. Consequently interactions with the
InputChannel might occur on the wrong thread. Fixed this
problem by checking the current thread and posting input
events or callbacks to the correct looper when necessary.
NativeActivity has also been broken for a while because the
default event handling logic for joysticks and touch navigation
was unable to dispatch events back into the native activity.
In particular, this meant that DPad synthesis from touch navigation
would not work in any native activity. The plan is to fix
this problem by passing all events through ViewRootImpl as usual
then forwarding them to native activity as needed. This should
greatly simplify IME pre-dispatch and system key handling
and make everything more robust overall.
Fixed issues related to when input events are synthesized.
In particular, added a more robust mechanism to ensure that
synthetic events are canceled appropriately when we discover
that events are no longer being resynthesized (because the
application or IME is handling or dropping them).
The new design is structured as a pipeline with a chain of
responsibility consisting of InputStage objects. Each InputStage
is responsible for some part of handling each input event
such as dispatching to the view hierarchy or to the IME.
As a stage processes an input event, it has the option of
finishing the event, forwarding the event to the next stage
or handling the event asynchronously. Some queueing logic
takes care to ensure that events are forwarded downstream in
the correct order even if they are handled out of order
by a given stage.
Cleaned up the InputMethodManager singleton initialization logic
to make it clearer that it must be attached to the main looper.
We don't actually need to pass this looper around.
Deleted the LatencyTimer class since no one uses it and we have
better ways of measuring latency these days using systrace.
Added a hidden helper to Looper to determine whether the current
thread is the indicated Looper thread.
Note: NativeActivity's IME dispatch is broken by this patch.
This will be fixed later in another patch.

started for any reason.
Also awaken when toggling recents (and not locked).

This is the best and only way for apps to listen for
notifications: create a NotificationListenerService, wait
for the NoMan to bind to you (as a result of the user
checking a box somewhere in Settings and agreeing to a
scary dialog box), and you'll start receiving notification
posted and dismissed callbacks. Your service, while enabled,
will also be able to clear one or all notifications.
Use this power wisely.
This change moves StatusBarNotification out of
com.android.internal into android.service.notification.
[Internal customers, including System UI and early users of
the system-only listener binder API, will need to be
updated.]

Make sure that apps that have access to restricted accounts can see them.
If they don't have access, they shouldn't be able to add a new account either.
Show an error message in the account picker if the user/app is not authorized.

A previous fix made initializing GL work better by calling eglMakeCurrent()
prior to querying the max texture size. However, that fix worked by creating an eglSurface
earlier than we did before, which for some reason causes problems later if wallpaper creation
fails and we back off to a software solution.
This new fix creates a temporary pbuffer surface instead, which still allows us to make the
call to eglMakeCurrent() prior to querying the max texture size, but does not result in the
later canvas lock failure if the wallpaper creation fails anyway.

ImageWallpaper was sometimes querying GL for a max texture size too early
(before the first call to eglMakeCurrent()). This problem caused the wallpaper
to then get created in software, resulting in noticeably slower performance
when the wallpaper was visible.
This fix ensures that the
makeCurrent happens before the query, ensuring that wallpapers of the right
size actually get created instead of failing due to this error at creation time.

Drawable has setAlpha(int), but no getAlpha() (although some subclasses have added the
method). This makes it more tedious to use the property. For example, animations that wish to
animate this property must explicitly give it a start value since this value cannot be queried
from the object.
The trick is that setAlpha(int) is abstract, only implemented by subclasses. We cannot take this
approach for getAlpha(), as we would break all subclasses of Drawable until they implemented the
method. Instead, we'll add a default method which returns an invalid value, making it easier for
clients of the method to detect whether the value is valid.
All subclasses of Drawble in frameworks have been changed to add an override of getAlpha() when
appropriate.
