With this CL, the previously used commit indicator was reverted.
Instead we use the add-to-dictionary indicator only at the moment.
This CL also fixes the indicator position in bidi context.

When CursorAnchorInfo is unavailable, we shouldn't try to show
the commit indicator and set the text highlight color.
With this CL, RichInputConnection can be used to track if the
application responded that it does support CursorAnchorInfo or
not. This result will be taken into consideration when
InputLogic needs to determine whether the commit indicator
should be displayed or not.

This is a groundwork for subsequent CLs where we need to
add/remove background color to/from the commited text.
In this CL, we use Spanned#SPAN_COMPOSING so that we can easily
remove such a background color by calling
InputConnection#finishComposingText. To make this operation easy
and realiable, we need to track whether we have specified the
background color to the commited text or not at one place. Here
we use RichInputConnection for this purpose.

There is a bug in ICS where the input connection won't take
any writing commands after rotation until the cursor moves.
This fixes it by wiggling the cursor position once before trying
to do anything.
Bug: 16810766
Change-Id: Ib14c70bd0550420cecfa86dea501d13a1a91e296
The symptom : when text is selected and the device is rotated,
sometimes the keyboard sets the word as being composed around
the start of the selection. Upon the next rotation this ends up
with the keyboard committing some text in place of the selection.
The cause : another bug in the framework with rotation >.>
The keyboard receives a call to startInput with a wrong cursor
position, namely one that does not represent a selection. The
keyboard sets a composition according to this wrong data. When
the keyboard is rotated again, it commits the text, which takes
the place of the selection.
The solution : actually when restarting input the keyboard
realizes that the cursor position is wrong. We cancel composition
at that time.
For robustness, this change also implements two other defensive
changes : upon call to onUpdateSelection, we actually realize
that the previous values were wrong, so we also fix it at that
time, and in addition, when rotating, we finishComposingText()
instead of commitText() which is less dangerous. Implementing
this later change also allows us to let less internal variables
from InputLogic escape to LatinIME, so it's also a good change
for design.

The heuristic in RichInputConnection makes little sense
when textLength > mExpectedSelStart but we have
more than 1024 characters of text. If there are that many,
it's about 100% sure that 1024 is not the correct cursor
position. With no good guess, we'll just continue trusting
the app, even though we know it's lying : at least it will
make the problem visible to the app author.
Also, there have been a lot of confusion about initialSelStart
and initialSelEnd. The keyboard should log them so that
it helps us and editor authors debug more easily these
common problems.
Issue #65170 in AOSP and
Bug: 12772035
Change-Id: I6665a16c9f2832d33ee323f033bb38bcc092a3b4
When the cursor is moved by the user, the RichInputConnection
is told about it. However, to work around a framework bug, it
also looks at how many characters are in the buffer before the
cursor, and if that's more than the value it's been passed, it
deduces that's a framework bug and there are at least as many
characters as seen before the cursor, so it puts the expected
cursor position there.
When you move the cursor, TextView calls onUpdateSelection,
and when you move it fast, you'll get rapid-fire calls to
onUpdateSelection. This is fine, the RIC is equipped to
deal with that.
However, these calls take some time to make it to the IME. In
this instance, when the first call gets through and the IME
calls TextView (synchronously) for text before the cursor, the
cursor has already moved in the app, and TextView returns more
characters than the cursor position was declared to be in this
instance, so the RIC sets that as the expected cursor position.
Sure enough, a split second later, the second call to
onUpdateSelection arrives, with the new cursor position set
where the RIC had found it too early. The RIC takes that as an
"expected" cursor move, and the input does not get reset.
Luckily, we have a way out. As far as we know, the framework bug
only manifests itself upon rotation, which means we should only
have to adjust for it in onStartInputView. Doing it in
onUpdateSelection is too zealous (and probably too distrustful of
the app to send the correct cursor positions).
So we should just take care of the rotation case (by calling
tryFixLyingCursorPosition in onStartInputView) and remove the
compensating code in resetCachesUponCursorMoves.

During recorrection, the cursor position when calling
commitText is not necessarily at the end of the
composing text.
Besides, RichInputConnection assumes the cursor is
always after any composing text. This is not correct,
but in the practice, it seems all code paths work.
We should fix this in the future.

This just mirrors what InputLogic#tryFixLyingCursorPosition
is doing. That method will go away in the next change.

This test was intended only for cases without a selection, and as
a safety net for cases where the app would pretend the cursor
is at N but we can get P chars from the editor where P > N.
When there is a selection, this is wrong. In the practice it works
because these values are not used in this case, but it's still wrong.
The case where P > N is arguable, but actually I see little reason
to trust the getTextBeforeCursor() method more than the
onUpdate selection method. Plus in the practice, I don't think
we are aware of any app with this bug, and it's probably not a
great idea to be too robust about this as it may encourage wrong
values sent to onUpdateSelection.

Don't use absolute cursor positions when making edits,
this leads to race conditions.
This is a bit ugly and will need to be fixed soon. Plans are
underway to clean this up.

This old method doesn't even re-read the old suggestions. It used to
recompute them without the coordinates.
Re-using the recorrection code, which is much more advanced, is
the right thing to do here.
Also, refining the test. It's no use trying to resume suggestion
if we don't have a suggestion strip, since we aren't going to
auto-correct anything anyway.
Not the motivation for this change, but this also fixes
