Description

Description

Hi,

I do have two tabs that host React Native as fragments in the android kotlin app. I would predictably see the app crashes if I switch between tabs that host React Native fragments. If I just go to one of the tab and not between them, the app functions longer. But it would crash within a few clicks on the tabs after I enter into two tabs that host RN fragments.

Steps to reproduce
  1. run yarn to install all the js dependencies
  2. run yarn start to start the metro server
  3. run yarn android to deploy to the connected android virtual device
  4. click back and forth between the two tabs in the app.
  5. then you would see the app crashes after not more than 10 clicks.

Research direction

Run the linked reproducer with the listed yarn, Metro, and Android steps, then switch between the two tabs while capturing the crash. Start with the stack-trace path through ReactFragment.java, ReactDelegate.java, and ReactInstanceManager.java, especially onHostPause; done means repeated tab switching no longer crashes the Android app.
