I got a problem with the State Codelab In Chapter 6 you are kotlinlang #compose

I got a problem with the State Codelab. In Chapter 6 you are building an input field which gets cleared when you press "add". but as soon you start typing again the text reappears. this seems buggy and I don't know why this is happening. I tested the finished solution from google but it also happens there. Did you also got this problem? why is this happening?

Can you share the versions / AS version you see this in (as it may be relevant)

AS: 4.2 Canary 11 Compose: 1.0.0 alpha 3 BuildTools: 30.0.0 or 30.0.2 (happens with both) Kotlin 1.4.10 Android gradle build tools 4.2.0-alpha11

Will cycle home now, I check back later if you need any more informations. Would be interested if you can reproduce it. 🙂

Tested it again at home on a Windows PC, cannot recreate the problem on an Android 11 Emulator. Will test tomorrow again at work a MacBook and will switch the device (was a Samsung S8, Android 9)

Same – sorry slow reply lots of meetings today. I've not yet reproduced it (trying for that before I go code diving)

Hey Sean, I think the problem is on my side. I tested it again, running on an Android 11 emulator and Android 9 emulator everything is fine but running on a real Samsung Galaxy S8 (SM-G950F) with Android 9 it happens. Maybe just another Samsung bug 🙄

Not reproducible on a Samsung S9+ with Android 10

That's quite unexpected – can I ask you to file a bug with all the versions
