Use Canary Leak to detect memory leaks?
r
its not memory leak, we do have leakcanary integration in debug variant to detect leaks during development. And this issue is not happening in all devices, QA team also unable to replicate this with same devices.
f
Copy code
Fatal Exception: java.lang.ClassCastException: androidx.compose.foundation.layout.q0 cannot be cast to androidx.compose.runtime.z0
Erm, Proguard? 😉
i don't see out of memory error in your log
r
proguard issue will happen in all devices if we install release apk
f
not always, i would say that you have specific use case in those devices
where layout cannot be rendered due to this class cast
might be a bug in jetpack
