@mehdichamouma I think we don't need to. React Native doesn't do that internally either.

@satya164 Turns out you absolutely need to. I lost a whole day because of this.
I'm using the react-native-google-signin package, they are firing a startActivityForResult.
If the call to super is omitted here, the onActivityResult on their side is never called and Google signin doesn't work.

I'm no sure why this happens, my Java is a little rusty, I'd definitely be interested in an explanation, if anyone can provide any :p

Anyway, the react-native-fbsdk docs are up to date now, hopefully no one else will stumble on this.

Thanks for this gist, everything works fine but FBSDKPackage cannot be found. Is there any way to import that package? Thanks.

Hi,
I am getting a strange error. Could anyone please help?

Native module AppStateModule tried to override AppStateModule for module name AppState. If this was your intention, return true from AppStateModule#canOverrideExistingModule()

Figured it out! It was my mistake. I tried to import MainReactPackage twice.

return Arrays.<ReactPackage>asList(
new MainReactPackage(),
new ReactNativePushNotificationPackage(),
new MainReactPackage(),
new FBSDKPackage(mCallbackManager)
);

Just gonna leave it here for anyone who runs into the same mistake.

Thank you, that was helpful :)
