There's no way to customize the fingerprint when an ANR occurs.

[RUOK90]

Problem Statement

When customizing the fingerprint using the SDK, it's typically done as follows:

options.beforeSend = (event, hint) {
event.fingerprint = ...
return event;
};

However, in the case of errors occurring at the native level, such as ANRs, the beforeSend callback is not triggered, making it impossible to customize the fingerprint. Consequently, we cannot group events as desired.

Solution Brainstorm

Unfortunately, I have no ideas.

DART-183 There's no way to customize the fingerprint when an ANR occurs.

hey ANRs are triggered by the sentry-android SDK and the beforeSend callbacks are not synchronized with the underlying native SDKs

I will have a look at what options we can offer for this

@antonis is it possible in RN to customize the native fingerprint in the JS layer? Or do you also need to initialize the native sdks separately in that case?

[antonis]

@buenaflor It's the same on RN. Initialising the native sdks and setting the fingerprint on Android is the only way at this point.

@romtsn wdyt? since this is about customizing fingerprints for ANRs does it make sense to have a way to customize the fingerprints in those cases without initializing native sdks manually?
