When enabling talkback while the Android editor is running, the editor crashes with the following errors

Should be fixed now.

A great start!

@bruvzg I got another crash testing your latest changes, this time after turning off talkback while the Android editor was still running.

I got another crash testing your latest changes, this time after turning off talkback while the Android editor was still running.

I was not able to reproduce it on the phone interface, might be specific to multi-window environment (or inconsistent), I will check it on weekend.

I was not able to reproduce it on the phone interface, might be specific to multi-window environment (or inconsistent), I will check it on weekend.

From the log, the crash occurs after a hover event so that may be hard to reproduce on a phone without a connected mouse or stylus to generate a hover event.
It may be easier to reproduce on the emulator.

bruvzg · 2026-08-17T06:25:55Z

Still was not able to reproduce the crash on any device (neither with touch, not with scrcpy emulated mouse, nor with directly connected mouse). Will try emulator later.

m4gr3d · 2026-09-03T17:06:43Z

@bruvzg Any updates on this PR? Were you able to reproduce the crash?

bruvzg · 2026-09-03T17:08:08Z

I was not able to reproduce the crash, neither on simulator nor on real devices.

m4gr3d · 2026-09-18T02:15:40Z

@bruvzg The issue is replicable on the Android simulator, however you need to use the Desktop AVD instead of the regular Phone / Tablet because those ones don't dispatch hover events.

You can check out these instructions for how to setup the Desktop AVD.

DataTriny · 2026-09-19T10:53:01Z

Actually the latest crash experienced by @m4gr3d is probably a bug in the AccessKit Android adapter. See the fix here.

@bruvzg will you be able to apply the fix ahead of the feature freeze?

bruvzg · 2026-09-24T18:04:51Z

will you be able to apply the fix ahead of the feature freeze?

Nothing in this PR should need changing, we use separate repo for custom AccessKit builds - https://github.com/godotengine/godot-accesskit-c-static

I'll test it on Saturday (and update our custom build repo).

bruvzg · 2026-09-26T09:15:58Z

I have tested it with desktop AVD, and was able to reproduce the crash. I can confirm it is fixed by AccessKit/accesskit#803

To avoid version mismatches, I'll probably wait for next official accesskit-c release before updating our custom build repo. It will also require a tiny, non-platform specific change to the main repo due to API renames, I will do a separate follow-up PR once it is updated. Should not really matter if this part is done before freeze or not, since AccessKit version update is not a new feature.
