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

This returns the wrong string, but since it's used for getting the
previous word for bigrams, it only results in slightly worse
suggestions quality.

The PARAGRAPH type of span is dangerous, as concatenating
CharSequences that contain it may crash. We also don't use
other spans than SuggestionSpans, so we don't copy them.

It's unclear what the concrete effects of this are, but they are not
very strong. This only happens in corner cases, when the input
connection is not active - while rotating, for example.

InputConnection#finishComposingText() should not change the position of the cursor,
so neither should it change its internal expectation of the cursor's position.

I548d899b introduced a new method to fix a sync miss between
the cursor position and the cached cursor position, but did not
take into account that it should also update the cached text
before and after the cursor in this case and that there was
already a method for doing this.

The documentation for setComposingRegion states explicitly
that it does not move the cursor. This is just a bug.
This does not have any ill effects right now, but it will have
in later changes if not fixed.
As for the selection handling, the specific test that this code
removes used to serve a purpose, but it does not any more because
the code using the value has been much sanitized. Now the variable
can just take the obvious value, and become so self-explanatory
that the comments are unnecessary.

- Don't call finishComposingText when useless.
- Add safeguards against calling setComposingRegion when the
data returned by the editor is inconsistent.
- Cancel pending recorrection messages when new messages arrive.

This is about as ad-hoc as it gets, but then again, what we want
is probably as ad-hoc as it gets.
All URL boxes I know of double as search bars, and not adding
automatic spaces there sucks (e.g. in Chrome URL bar).
And in other boxes actually you don't want to add a space if
it looks like a URL. QSB isn't even a search box, and it behaves
like this.
So I think this is actually the right answer to the problem.
