Disclaimer: The instructions are the collective efforts from a few places online. 
Nothing here is my original. But I want to put them together in one place to save people from spending the same time as I did.

First off, bundle.
==================

1. cd to the project directory
2. Start the react-native packager if not started
3. Download the bundle to the asset folder:
curl "http://localhost:8081/index.android.bundle?platform=android" -o "android/app/src/main/assets/index.android.bundle"

1. Store api keys in a xml file

Put xml file "api_keys.xml" in the directory "res/value/".

api_keys.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="THE_MOVIE_DB_API_TOKEN">XXXXX</string>
</resources>

AppBarLayout appBar;
appBar.addOnOffsetChangedListener(new AppBarLayout.OnOffsetChangedListener() {
    @Override
    public void onOffsetChanged(AppBarLayout appBarLayout, int verticalOffset) {
        if(verticalOffset > -300) {
            collapsedAppBar.setTitleEnabled(false);
        }
        else {
