undefined is not an object _InCallManager.start

I’m trying to install this for android and it’s not working. All I did was

1. npm install
2. import InCallManager from ‘react-native-incall-manager’;
3. InCallManager.start()

And I am getting the error: undefined is not an object (evaluating '_InCallManager.start')

For anyone that has an issue with Android, I had to manually add the following to MainApplication.java

import com.zxcpoiu.incallmanager.InCallManagerPackage;

    @Override
    protected List<ReactPackage> getPackages() {
      mReactNativePushNotificationPackage = new ReactNativePushNotificationPackage();
      return Arrays.<ReactPackage>asList(
          new InCallManagerPackage(),
      );
    }
