hey @maleking thanks for raising this

could you enable the debug mode and copypasta the logs, please? thanks.

[maleking]

how to enable debug mode in sentry @marandaneto ?

[marandaneto]

@maleking
just pass the debug flag on the SDK init.

Sentry.init({ 
  dsn: 'dsn...', 
  debug: true
});

[maleking]

this is sentry log in ios simulator and android:

Sentry Logger [Log]: Integration installed: ReactNativeErrorHandlers
Sentry Logger [Log]: Integration installed: Release
Sentry Logger [Log]: Integration installed: InboundFilters
Sentry Logger [Log]: Integration installed: FunctionToString
Sentry Logger [Log]: Integration installed: Breadcrumbs
Sentry Logger [Log]: Integration installed: LinkedErrors
Sentry Logger [Log]: Integration installed: UserAgent
Sentry Logger [Log]: Integration installed: DebugSymbolicator
Sentry Logger [Log]: Integration installed: RewriteFrames
Sentry Logger [Log]: Integration installed: DeviceContext

@maleking this is the log from react-native (JS layer), I'm more interested in the Android logs (from logcat), you can copy-paste that from AS.

I need to understand the output of the error in order to test and reproduce it, thanks.

I'm experiencing this issue too - let me get some logs today and post them here.

[marandaneto]

@crobinson42 please share some logs :) thanks

[maleking]

@marandaneto I call Sentry.nativeCrash() in release apk and this is AS logs
log.txt

[marandaneto]

@maleking are you running in release mode?
The log states: TEST - Sentry Client Crash (only works in release mode)

[maleking]

yes, i created a signed apk with ./gradlew assembleRelease command and then capture the log with logcat

[marandaneto]

@maleking this is likely not the right thing, because logcat is not available on release builds.
I have a question though, when you call Sentry.nativeCrash(), do you experience a hard crash or do you get that Redbox screen on your App?

[maleking]

@marandaneto I get a hard crash of course because its a release build :)
what do you means logcat not available on release builds ?
i always check logcat for debugging crash in release mode
i add this line in App.tsx

 Sentry.init({
    dsn: SENTRY_DSN,
    debug: true,
  });

and then in home screen i define this

<Button
  title="crash"
onPress={() => {
 Sentry.nativeCrash();
   }}
    />

[tlrobinson]

I am seeing this too. Throwing an uncaught JS error or calling Sentry.captureException works, but calling Sentry.nativeCrash() is not reported. Release build, and I open the app again after the crash.

react-native 0.63.2
@sentry/react-native 1.8.2

[shubhamkes]

Did this issue solved? I am still facing it @^2.1.0

[marandaneto]

can you double-check that the flag enableNativeCrashHandling is still true?

@jennmueng could you have a look at this?

[shubhamkes]

thought its enabled by default. Though added now but still cant see logs in dashboard

[jennmueng]

@shubhamkes Just to confirm, does the app actually crash for you and nothing is reported, or does the native crash method do nothing? We have tested this out on our end to confirm that it should be working and if it’s not working for you I believe the issue is most likely with the installation or some configuration.

It would greatly help us if you can provide a producible example in a repo for us to try out to be able to give you a clearer answer.

Hi @marandaneto I am facing the same thing on Android and it shows the error in red box. But on iOS it's working

[marandaneto]

@yasirtrimulabs well as stated before, and also in the red dialog, it works only on release mode.

[marandaneto]

@jennmueng could you run a hard crash on the latest RN on Android, please? just to be sure it works.

[yasirtrimulabs]

@marandaneto I fixed it by following this

[jennmueng]

@yasirtrimulabs That was what I assumed, as the dev menu should never show on release mode.

[marandaneto]

@jennmueng should we close this issue then?
