6c8217ab3072fa65851316a922b482506b3c2a4c 25-May-2016 Winson <winsonc@google.com> Defer calling the stack task removed callbacks.

- When updating a TaskStack, defer calling any callbacks until the stack
is updated. Otherwise, the handler may incorrectly check the size of
the stack to be empty, which triggers Recents to go home.
- This CL also removes an erroneous double call to onStackTaskRemoved()
when updating, one explicit call and the call that is made internally
in removeTask().

- This CL removes the dependency on the last-active-time of the task
record, since that is dependent on the current system time (which can
be changed by the user). Instead of working around the previous
behavior in ActivityManager which moves all affiliated tasks to the
top when one task is launched, we change the behavior in the AM
directly, and prevent re-sorting the list of recent tasks improperly
(aside from the stable sort which puts the freeform tasks first).

- Accounting for the inset when calculating the final stack bounds
(similar to b/27921362)

- Fixing issue with onResume logic being run even when the window focus
is changing. This only needs to be run when we are launching into
Recents again.
- Removed a bunch of launch state flags that are no longer necessary
because of changes to configuration handling. This reduces the work
that we have to do on resize, etc.
- Decoupled the resume with the stack-update, which fixes a couple
issues where we were updating the layout unexpectedly.
- Fixed an issue where we were not updating the nav bar scrims on
configuration change
- Fixing margin start/end regression in header bar
- Fixing small issue with paddings being scaled beyond their base size
- Fixing issue where the clip state was not properly getting reset
causing lots of overdraw.

- Tweaking initial layout to show more of the next task
- Bounding the width of the stack to the smallest display edge length
- Fixing issue where the screen pinning button was not shown when
entering recents from home, and the task view clip state was not
restored correctly for tasks in front of the launch task.
- Fixing issue where there was no alpha during the transition to/from
home
- Refactoring and removing unused dimens, and moved remaining layout
calculation logic out of RecentsConfiguration.
- Fixing small regression in finding task anchor scroll points. This
caused tasks to be animated strangely when swiping to dismiss and
the task had an override task progress.
- Fixing several regressions in drag and drop due to override progresses

This CL fixes a long-standing issue in which Recents is not updated
correctly if it is not completely hidden and shown. In particular, it
would cause animation issues when launching into a non-fullscreen
activity or if the user quickly toggles between recent tasks. It
contains several fixes:

- The visual state in Recents is no longer reset until the activity is
fully hidden (onStop() is called), and the task stack state is saved
allowing us to return to the same initial state. When restarting the
activity, we propagate whether the activity was hidden down the view
hierarchy, so that each task can decide whether to reset itself.
- When the recents activity is started, we now merge the new stack with
the current stack instead of replacing it completely. This unifies
the logic when dismissing multi-window while Recents is open, and this
CL fixes an issue with the merging where onStackTaskAdded() was called
before the stack was updated with the new task. As a result of this
change, we can just rebind the task views without having to return and
pick them up from the view pool.
- This CL also fixes an issue with flashing when the screen turns off.
The activity onStop() can be called before the activity is fully
hidden, which would trigger a reset(), which would return all views to
the pool.

- Adding notion of a TaskViewAnimation to animate a TaskView to a
specific TaskViewTransform
- Refactoring task view enter/exit/launch/delete animations into
a separate class so that we can improve them easier
- Removing individual TaskView view property animations in favor
of using the existing TaskStackView stack animation. This ensures that
we don't have to add separate logic when animating TaskViews. It is
all handled by the TaskStackView now.
- Breaking down the TaskStackView synchronize method into binding
TaskViews and updating them to transforms. This allows us to
synchronously update in many cases and is cleaner than the many
request* calls.

- We can no longer make assumptions about the ability to

is launched (the configuration of the launched activity
can differ than the current configuration if a window

to the set of values that are context agnostic, or can
be calculated directly given an application context.
This ensures that we will continue to be able to compute
the target task bounds given any context.

This will remove the need for having all the null checks in TaskStackView.
We also remove the check when launching tasks (the fail case is worse
when the activity fails to load). And the CL also fix the header focus
animation, and an issue with tasks not getting laid out when the stack is
set again.

a4ccb86ddc8f9f486aee25fb836f4aff97bf7679 23-Aug-2014 Winson Chung <winsonc@google.com> Multiple performance changes to speed recents invocation/app launching time. (Bug 16987565)

- Reverting changes to the existing thumbnail transition to prevent breaking applications
that currently depend on that transition. As a result, we need to create a new, hidden,
aspect-scaled thumbnail transition, and instead use that thumbnail to animate the
recents header so that we don't have to wait to do that inside the Recents activity.

In order for this to work, we also have to ensure that the thumbnail surface destruction
is synchronized with the application that is currently closing (when going down to
recents) or opening (when coming back up). The current thumbnail is destroyed when the
animation ends, but that can be at least 1 frame before the surface for the animating
window is destroyed. We change this by deferring destruction of this thumbnail window
to the animation that is being closed.

Especially on the way up, not having to wait for us to hide the header before doing the
transition up can save us the duration of that first animation (> 100ms).

- Other optimizations:
* No longer creating a new stack view on each transition to calculate the target rect
* Removing unnecessary call to get the thumbnail when transitioning up/down (the actual
window does its own animation.
* We reduced numerous system calls per task by adding a flag to ignore home-stack tasks
and caching the activity label and icon (and task description icon). These caches
follow the same eviction schemes as the thumbnail and icon cache.

- Also tweaked the touch slop for the nav bar swiping gesture to prevent conflicting with
tapping on home (Bug 17109581)
