Jitsi React Native Custom Build - Dependencies fail for Android

Hi, We are trying to build a custom jitsi build for our project using the latest React Native 0.61.1.

We need to use the following dependencies for our project:

The steps we followed:
cd jitsi-meet-master
npm install
npm install --save react-native-contacts
npm install --save react-native-device-info
react-native run-android

Inside the WelcomePage.native.js file:

import Contacts from 'react-native-contacts';
import DeviceInfo from 'react-native-device-info';


  console.log('Contacts=',Contacts) //Returns null
  console.log('DeviceInfo=',DeviceInfo) //Crashes with Red screen 


Everything works well with iOS (tested on iOS 12 & 13). Also, all the dependencies work well outside of Jitsi (i.e. we are able to read contacts & deviceId). Only for android build, that too only for dependencies we add on our own has this issue.

Let me know what we are missing.

Thank you!
