Hi @benvinegar . Thanks for the super prompt update. The crashing is fixed :) But as I was not receiving any event, I added an "throw new Error('test')", just to verify that sentry is properly setup. But I wasn't getting any event still. The following is the error log.

@qbig – I notice this is when running on Android. Do you get the same exception from the iOS simulator / iOS devices?

[benvinegar]

@qbig – any news on this?

[qbig]

@benvinegar I have tried on iOS simulator. It wasn't throwing the same exception. But I wasn't getting any events either. ok. I could get event now. Would try on android again. Let you know how it goes.

With RN0.18, it's not crashing anymore. So maybe can close this issue

[qbig]

I was testing with Android emulator(Genymotion), and I have limit the length of the stacktrace to 1000 characters. But it only works on dev Mode. Once I build it to a release version apk, JS error would simply crash the App and no msg would be logged to Sentry.

    ErrorUtils.setGlobalHandler(function(){
      var error = arguments[0];
      defaultHandler.apply(this, arguments)
      console.log(JSON.stringify(error));
      error.stack = error.stack.substring(0,1000);
      Raven.captureException(error);
    });

I suspect this is caused by the different behaviours of defaultHandler.apply(this, arguments) in dev and prod mode and the app crashed before any stacktrace was sent to Sentry

React Native's default behavior (on iOS) for global exceptions is to re-throw the exception in Obj-C land, causing an immediate crash (and no chance for Raven to upload the exception)
