SDK Version: 48
I wanted to share my experience with using Expo packages in my RN/Android project. While researching, I came across some mentions that Expo doesn’t support new architecture. However, I noticed that most of the packages support Fabric, so I decided to use them in my project. The build and functionality of my app worked well, except for one feature of React Native - ‘Concurrent React’.
To enable Expo modules support, I followed this guide (link 1), which involved wrapping DefaultReactActivityDelegate in ReactActivityDelegateWrapper from ExpoSDK. The second parameter, BuildConfig.IS_NEW_ARCHITECTURE_ENABLED, allows React Native to enable concurrentRoot in the app. However, I noticed that ReactActivityDelegateWrapper from the SDK doesn’t pass this flag to the super class (link 2), causing unexpected side effects.
I wanted to clarify the status of SDK support for new architecture (incl. React 18 feats) and whether it is expected behavior to pass a false flag to ReactActivityDelegate. Any insights or feedback would be greatly appreciated.
