If you are using sentry.io, please post a link to your issue so we can take a look:

BLOOMTEXT-MOBILE-NX

Configuration:

(@sentry/react-native)

    Sentry.init({
      dsn: SENTRY_DSN,
      enableAppHangTracking: false,
      enableWatchdogTerminationTracking: false,
      beforeBreadcrumb (breadcrumb) {
        return breadcrumb.category === "action" ? breadcrumb : null
      },
    })

Also tried:

     ...
      integrations: function (integrations) {
        return integrations.filter(function (integration) {
          return integration.name !== "Breadcrumbs"
        })
      },
     ...

(AndroidManifest.xml)

<manifest>
  <application>
    ...
     <meta-data android:name="io.sentry.breadcrumbs.activity-lifecycle" android:value="false" />
     <meta-data android:name="io.sentry.breadcrumbs.app-components" android:value="false" />
     <meta-data android:name="io.sentry.breadcrumbs.app-lifecycle" android:value="false" />
     <meta-data android:name="io.sentry.breadcrumbs.system-events" android:value="false" />
     <meta-data android:name="io.sentry.breadcrumbs.user-interaction" android:value="false" />
   </application>
</manifest>

I have following issue:

Despite filtering on breadcrumb.category === 'action', network.event and app.lifecycle breadcrumbs are captured. Disabling automatic breadcrumbs in the Android manifest as described here doesn't suppress these, either.

Steps to reproduce:

• Trigger any error

Actual result:

Breadcrumbs contain not just action but also network.event and app.lifecycle breadcrumbs. On iOS, there are even more categories, including 'ui.lifecycle' and touch...

Expected result:

Breadcrumbs contain only "action" items.

Should add that some breadcrumb categories (e.g. console) are being filtered out as expected with this setup.

I suspect beforeBreadcrumb is only processing "browser" breadcrumbs, but not "native" breadcrumbs -- if that makes sense.

Hi,
thank you for the message and details.

beforeBreadcrumb callback is executed only for JS Breadcrumbs. Native breadcrumbs are added by our integration later on. To only receive breadcrumb.category === 'action' you can filter the final breadcrumbs in beforeSend.

At the moment this won't work on Android due to the current way of scope synchronization. More information about the issue here.

The AndroidManifest.xml options are ignored because the RN SDK initializes the Android SDK. To change the Android Breadcrumbs options you would need to initialize the SDK manually.

Thanks for the explanation -- good to know that this is a known issue/limitation.

I'll close this issue since the core problem is described in getsentry/team-mobile#11
