Error after clicking on my app icon during sharing (Expokit, Android)

[flo-wolf]

I am running an ejected expo project (Expokit, SDK 36).
I have managed to install the module successfully and my application appears in the list of apps to share to for the specified mime types.

Though when I click my app icon, I get the following error:

Index.js:
The problem might be related to the index.js, which was not automatically created for me after ejecting from Expo, Thus I created my own index.js in the root folder where App,js is located and inserted the following, exactly as stated in the installation instructions (note that prior to the installation of this module this index.js did not exist and the app ran fine):

//index.android.js
import React from 'react'
import { AppRegistry } from 'react-native'

import App from './app.android'
import Share from './share.android'

AppRegistry.registerComponent('VoiceKeep', () => App)
AppRegistry.registerComponent('MyShareEx', () => Share) // TODO: Replace MyShareEx with my extension name
