[Android] Elevation shadow blink bug using MaterialContainerTransform

Question

(I am not really sure if it's right to ask such a library-specific question here since it's been long visiting SL. I have tried raising the same bug in a Stackoverflow question(https://stackoverflow.com/q/71338984/9520315) and also have reported an issue for the same but with no luck so far(https://github.com/material-components/material-components-android/issues/2592 ))

Description of the issue in short :-
When doing a shared element transition from one activity to another, the specific card involved in the transition is blinking after landing back.

Any help would be appreciated 🙂

Answer 6

Double + To clear all the details in one go:-
-> I am using Android Studio and Java but I think it has nothing to do with the bug.
-> The app is running fine expect that animation is causing a shadow blink effect which is unexpected.
-> The transition part of code is inspired from the official Material 3 Docs so I don't know what I am doing wrong.
-> The issue is only happening when I am specifying the card elevation but I want it as it is.
-> The demo video shown is from a real device though and it's running the release version from Play Store.

Answer 7

Double + It's connected in different activities & files and I think word limit will just exceed if I try to post all of it. That's why I added the Github link to give a better idea :)
