Getting the same error on a OnePlus 8 Pro running Android 11:

I am getting the same issue in firebase test lab; on Pixel 7 API 33. Unable to replicate it. Happens in a compose based ModalBottomSheetLayout with a parent Column, several child Rows and a LazyColumn that holds rows with text.

We also started to receive this crash on error reports, after upgrading activity-compose to 1.6.1. Any update on this?

Halil I vaguely remember that you fixed a similar issue recently or mentioned about it (a 1 off error for getHorizontalPosition).

Does this sound familiar?

• java.lang.IndexOutOfBoundsException: measureLimit (120) is out of start (0) and limit (119) bounds

Yes this is the same bug that we've investigated priorly. Both originate from AccessibilityDelegateCompat and use getBoundingBox. The underlying issue is in the platform TextLayout but we can circumvent the issue by falling back to previous implementation for the last cursor position.

I looked at this a bit more yesterday. Some of my findings include;

• This has always been buggy unfortunately. Previous getBoundingBox implementation also had a call to getPrimaryHorizontal(offset) that is the culprit from platform.
• getPrimaryHorizontal(offset) always fails in a situation similar to following;
  • Text is ellipsized.
  • Ellipsis region includes an LF character '\n'
  • offset points to a character after this LF
• TextLine object in text layout is set with a start and limit on given text.
• Limit does not care about ellipsis but cares about LF characters. So, a text is always guaranteed to be partitioned into multiple lines in the existence of LF.
• Querying an ellipsized offset which would have been on a different line anyway causes a crash on TextLine since TextLine thinks that the given offset is out of bounds.

There is a comment in TextLayout.kt that references a similar problem with platform text layout https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:text/text/src/main/java/androidx/compose/ui/text/android/TextLayout.kt;l=445?q=TextLayout.kt
