Crashes on OS 13 Samsung Galaxy

Following are the stack traces from Crashlytics, they show Open Telemetry which you use under the hood (we use your android sdk):

It would be good if we had a way to swallow these exceptions as they run through Open Telemetry. It is hard to know where they originate from.

Hey @ber4444 ,

I'm not sure I follow, how is the fact that you're getting these exceptions connected to the OTel instrumentation? They seem to be caused by actual network issues happening with your app.

The TracingInterceptor juts means that that particular HTTP call was instrumented; it's not the cause of the exception.

[ber4444]

It's definitely an exception handling issue on our end, just saying that pinpointing the source is not easy, perhaps you could you provide a helpful stacktrace as you see these IOExceptions come through.

[breedx-splk]

@ber4444 Just checking the obvious -- are you actually configuring a hostname of "xxxxxx" somewhere? Or did you just xxxxx that out manually because it is sensitive?

In any case, I think that both Fatal Exception: java.net.UnknownHostException: Unable to resolve host "xxxxxx": No address associated with hostname and Fatal Exception: java.net.SocketTimeoutException: timeout are pretty helpful and descriptive.

What kind of additional helpful information are you looking for?

[ber4444]

Yes, that is X'd out to hide the actual host name. I am looking for the REST API path to know which call is missing proper exception handling, since we have a numbers of API's on the same domain (the second exception isn't even descriptive of the domain btw). We actually fixed it already by hunting through the codebase but in a much larger project it would have been a massive pain.
