Comece em ReactHostImpl.kt, em onHostPause, e reproduza o crash usando o branch obrigatório rn-tester e o fluxo de tela dividida/compartilhamento descrito na issue. Está concluído quando várias instâncias de ReactActivity em primeiro plano não causarem mais a assertion nem o crash quando uma atividade for pausada; compare o comportamento com o pull request vinculado #54122.

Description

In our app's telemetry tools we are seeing crashes with the following stack:

java.lang.AssertionError: Pausing an activity that is not the current activity, this is incorrect! Current activity: ShareActivity Paused activity: MainActivity
    at com.facebook.infer.annotation.Assertions.assertCondition(Assertions.java:88)
    at com.facebook.react.runtime.ReactHostImpl.onHostPause(ReactHostImpl.java:347)
... full stack below

There is a bit of history around this issue:

And recently meta added changes to simply turn this assertion off by a feature flag:

For our use case the issue seems to caused by the fact that we have multiple ReactActivity instances.
The code in ReactHostImpl.kt is kind of build on the assumption that there will only ever be one active activity:

  • Historically the ReactInstance which ReactHost maintains was on the old arch bound to the ReactActivity, so it made sense that it was just caring about one activity
  • It's very well possible to have multiple activities in the foreground. Examples are share extensions, picture in picture mode, split screen app usage (and probably other stuff i can't think of right now)

I opened a PR which addresses this behaviour:

Steps to reproduce
  1. Clone this branch: https://github.com/hannojg/react-native/tree/fix/android-onpause-host-properly-reproduction
  2. It contains a new activity that you can share to: https://github.com/hannojg/react-native/blob/96defe6865a37e47068fdbc0a86df746bb8998aa/packages/rn-tester/android/app/src/main/AndroidManifest.xml#L92-L111
  3. Follow the reproduction steps from this video:
  • Open the rn-tester app
  • Move it to a split screen view
  • As second view for split screen choose gallery
  • Share a picture from gallery to the RNTester app
  • Now both the RNTesterActivity and RNTesterShareActivity will be in foreground and in resume
  • In the rn-tester app go to API > Share
  • Share text from the first button. Opening a share dialog will pause the RNTesterActivity, which will lead to a crash the whole app, as the last active activity tracked was RNTesterShareActivity
