Android SDK not working on a React Native app

SDKs
1

I have a React Native application where Sentry is already setup and working flawlessly. However, I’d like to capture errors from Android’s native code as well, so I followed this documentation https://docs.sentry.io/platforms/android/. Even though I followed it exactly as the instructions say, I still can’t capture error from the native code.

Here is my git diff (you can also see it here):

the Sentry React-Native SDK already bundles sentry-android underneath, you don’t need to set anything manually.
