Correlate ANR events to Mobile Screens (show in insights)

[bcoe]

Problem

I've gotten reports that customers with popular mobile applications can receive, in some cases, 1000s of ANR issues a day. With this volume of ANR issues, it's difficult to sort out signal from noise.

Potential Solution

A thought on my mind, if we included ANR information in Mobile Screens, with additional contextual information surrounding the ANR, e.g., an ANR error happens most frequently when interacting with widget X (getsentry/sentry-dart#2251), could we provide enough context surrounding these issues that they're easier to manage and debug.

Additional Notes

Once we have this additional context, we should cross link ANR issues and insights.

We need to complete the following tasks before tackling this issue:

• ANR improvements on Android: [Android] ANR improvements sentry-java#3934
• App hang improvements on Apple: [Apple] GA App Hang Rate & Improvements sentry-cocoa#4927
• Mobile SDKs must correctly detect the screen name and we most likely need a manual API for setting the screen name
• The screen name needs to be searchable in the product
