Make IMM more robust to spurious window focus-in
Change-Id: I1d9a138798d982f2164907b49713a7b90cec9adc
InputMethodManager (IMM) has a latch switch named IMM#mHasBeenInactive
to forcefully refresh IME focus state when an inactive client
(IMM#mActive == false) is gaining window focus. However, it turns out
that there is a race condition where the latch could be unexpectedly
turned off. This is probably what we have been chasing in bug 25373872.
Imagine the following scenario:
1. An app receives MSG_WINDOW_FOCUS_CHANGED w/ hasWindowFocus=false
2. IMM inside the app receives MSG_SET_ACTIVE w/ active=false
3. The app receives MSG_WINDOW_FOCUS_CHANGED w/ hasWindowFocus=true
4. The app receives MSG_WINDOW_FOCUS_CHANGED w/ hasWindowFocus=false
5. The app receives MSG_WINDOW_FOCUS_CHANGED w/ hasWindowFocus=true
Here, our current strategy has been:
A. Turn on the latch when MSG_SET_ACTIVE (w/active=false) is handled.
B. Turn off the latch and ask IMMS to start input when
MSG_WINDOW_FOCUS_CHANGED (w/ hasWindowFocus=true) is handled.
The problem is that in the step B IMMS can reject the request if
WindowManagerService (WMS) tells that the window in question no longer
has window focus. This is not surprising because the app is
just handling messages in the message queue sequentially. As a result,
the IME focus is not updated expectedly in the step 5, because the latch
is no longer enabled as we expected.
With this CL, the latch will be re-enabled if the app fails to start
input while IMM#mActive is false as a short-term solution.
In future we may want to address this issue in protocol level so that
we can address other known issues such as bug 26851566 at the same time.

Children should have backgrounds
Change-Id: I1f68467af9048b93631c33243f4a2dd2e67ccf81
To add a background to children of a group, a couple of things
are changed when a group is in the expanded state:
- The parent's shadow + background is removed
- The group header is given a background and elevation
- The children are elevated to cast a shadow and have backgrounds
- When it's fully expanded the dividers won't be shown
- There's extra height added to the parent so that the child
may cast the bottom shadow of the group
- As the children move into the bottom stack the last visible
one alters its height and the ones below it are hidden
to achieve the clipping effect

TalkBack is seeing crashes that I can only explain by our assumption
that window layer is unique in all cases. TalkBack reports that it
happens during animation, so I assume that the layer may repeat
transiently.
Reducing our dependence on this assumption by traversing the list of
windows sorted by layer without assuming that the list has the same
length as the list of unsorted windows.
Also documenting the undefined behavior of SparseArray when indexing
beyond its bounds. The undefined behavior itself is intentional for
performance reasons.

- Added ActivityOption to mark a starting activity as a taskOverlay
activity. That is the activity will always be the top activity of the
task and doesn't cause the task to be moved to the front when it is added.
- Only set the starting window state of the ActivityRecord to shown if
window manager actually showed the starting window for the activity.
Avoids incorrectly trying to remove starting window for an activity that
didn't show any.
- When starting additional activity in a task, transfer the starting
window from the top most activity with a starting window. It is possible
the top most window does have a starting window like in the case of the
forcedResized activity.
- Only ensure visiblity of an activity we are starting in a task whose top
activity is a task overlay. They need to start in the visible-paused state
and not the resumed state which just causes extra churn in the system.
- Always add additional starting activities in a task with an overlay
activity below the overlay activity.

We need to incorporate task bounds when calculating the inset hint

immediately after.

This is a follow-up to my previous CL [1] for Bug 15922840 so that we
can clear the following variables in a more reliable way.
- PhoneWindowManager#mLastInputMethodWindow
- PhoneWindowManager#mLastInputMethodTargetWindow
The idea behind CL [2] is that when InputMethodManagerService (IMMS) is
switching from an IME to another IME, IMMS can send a signal to
WindowManagerService (WMS) to remember the current IME's inset so that
the system can continue using it to reduce jank until the new inset is
specified by the next IME. As summarized in Bug 28781358, however, if
the next IME does not show the window after the IME switch, WMS (or
PhoneWindowManager to be precise) keeps using the previous IME's inset
unexpectedly until the new IME shows its window. All we have seen in
Bug 15922840 and Bug 26663589 fall into this category.
The idea of this CL is just adding a hidden API to InputMethodManager so
that InputMethodService#clearInsetOfPreviousIme() can surely terminate
the IME transition state managed in PhoneWindowManager, rather than
relying on a hack of calling SoftInputWindow#show() and
SoftInputWindow#hide(), which actually does not work for Bug 26663589.

Note that addressing all the corner cases in [2] still requires lots of
non-trivial change. Hence this CL focuses only on Bug 26663589 (and
the case we handled in Bug 15922840).

Close leaked windows when trying to preserve main one
Change-Id: I20b5d6ab8adbb97cffca52e1daf66ed939d508b8
Currently every focus change causes a freeform window to jump
for a few frames. The size of the jump is equal to the difference
in inset size (which is derived directly from the window elevation).
This problem goes away for most real use cases if the insets are
not allowed to decrease.

This CL fixes 2 bugs in View's addFocusables implementations.

2) addFocusables(list, dir, mode) was not respecting the provided mod.

When app has several windows and activity is relaunched + we try to preserve
main window - other windows just stayed around until removed by timeout or
replaced by app. There was a problem when one of the windows registered
broadcast receiver and set its own timer to remove it. In this case all
receivers were removed by framework because windows were considered leaked
and apps' timer caused crash when trying to remove registered receiver.
This CL removes all windows expect the main one, which we're trying to
preserve in this case.
