Should I file a bug report for this one?

[jim]

Looks like that API was changed a week-ish ago (https://android-review.googlesource.com/c/platform/frameworks/support/+/1544024/12/compose/u[…]tlin/androidx/compose/ui/text/input/TextFieldValue.kt), how old is your snapshot?

[Kshitij Patil]

Okay, so this issue occurs in the snapshot I mentioned. Has it fixed in any latest one?

[jim]

Looks like the snapshot you mentioned (7094152) which was built approximately 2021-01-20 but the CL was merged approximately 2021-01-15, so I suppose that CL broke that snapshot. Yes, please file a bug and include a repro. Looks like the problem is not directly related to TextFieldValue which accepts an AnnotatedString in your build, but is instead somehow related to savedInstanceState. cc @Siyamed

Oops, thanks for the heads up. Not sure how exactly this happens but let me check it. Meanwhile if you can create a bug i will appreciate it.

[Siyamed]

Actually, i dont think we ever wrote an AnnotatedString serializer😱

Hi @Kshitij Patil I cannot reproduce the exception unfortunately. I suspect of a line but I cannot understand the use case, or how this happened, and without the repro I am afraid I wont be able to properly fix this.

Pass String to TextFieldValue put app in background and bring back to foreground, it'll crash
