Mobile Session Replay causing ANRs in Android

[johnnywang]

Describe the bug

Wasn't sure where to report this, but the NPM package for mobile replay points here. I know mobile session replay is still in alpha, but thought the devs working on this might still find a bug report useful. Please close if not relevant.

Reproduction steps

I don't have a minimum viable repro, but this was enabled in the recommended fashion using:

function onDatadogInitialized() {
  SessionReplay.enable({
    defaultPrivacyLevel: SessionReplayPrivacy.MASK_USER_INPUT,
    replaySampleRate: 100, // Session Replay will be available for all sessions already captured by the SDK
  });
}

...

      <DatadogProvider
        configuration={DatadogConfig}
        onInitialization={onDatadogInitialized}
      >

Hey @johnnywang, thank you for reaching out and reporting this issue.

There are various improvements coming for session replay in the near future. We have received some reports of ANRs on Android, and they have a high priority in our roadmap.

Thank you for including relevant logs, they are really helpful!

We will inform you here on GitHub as soon as we have any further updates on the topic.

This is happening to us as well. We have had to remove Android Session Replay from the app, which is very annoying. We would be very grateful if this issue is solved !

Hello👋

Could you try using the most recent version of React Native (currently v2.4.3) and check if the issue persists?

We have addressed a common cause of ANRs with PR #671, and we have also updated the native Datadog SDKs to the latest versions, which come with many improvements and fixes.

We will be glad to help you resolve the issue if it still occurs.

Thank you!
