I've encountered the same issue while following the React Native tutorial (developing on Linux and targeting Android).

This issue helped me resolve the problem in following steps.

(in project directory) mkdir android/app/src/main/assets
react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res
react-native run-android
You can automate the above steps by placing them in scripts part of package.json like this:
"android-linux": "react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res && react-native run-android"

layoutanimation on android not work

import {UIManager} from 'react-native';

constructor() {
    super();

    if (Platform.OS === 'android') {
      UIManager.setLayoutAnimationEnabledExperimental && UIManager.setLayoutAnimationEnabledExperimental(true);
    }
  }

firebase.database is not a function

I ran into this with Ionic and it turned out that I wasn't including everything when using the latest Firebase Client. If you've included Firebase as firebase-app, then the Database and Auth pieces need to be required separately since they aren't bundled when including Firebase in this way.

Add the following to your index.html after you include firebase-app.js

<script src="https://www.gstatic.com/firebasejs/3.1.0/firebase-auth.js"></script>
<script src="https://www.gstatic.com/firebasejs/3.1.0/firebase-database.js"></script>
Obviously you don't need to use the CDN, you could use bower (probably the preferred way with Ionic) or NPM with Browserify.

// Browserify Setup
var firebase = require('firebase/app');
require('firebase/auth');
require('firebase/database');
Snippet below taken from the Firebase Web Setup Docs

You can reduce the amount of code your app uses by just including the features you need. The individually installable components are:

firebase-app - The core firebase client (required).
firebase-auth - Firebase Authentication (optional).
firebase-database - The Firebase Realtime Database (optional).
firebase-storage - Firebase Storage (optional).

From the CDN, include the individual components you need (include firebase-app first)
