The Expo SDK requires Expo to run

[ahdam]

Hello there,

I followed the toturial, and everything is fine on iOS, but on Android, even though it builds is ok, I get this error when trying to run the app on the simulator

W/ReactNativeJS:
No native ExponentConstants module found, are you sure the expo-constants's module is linked properly?
E/ReactNativeJS: The Expo SDK requires Expo to run. It appears the native Expo modules are unavailable and this code is not running on Expo.

I think it's because of the expoKit/expoCore versions (which are different from the ones in the tutorial). Something is different from your version after ejecting. Can you help fix this?

Thanks
