React Native turn off Debug mode and stop displaying warning messages

I currently have a scenario where warning messages are turning up on my production app, It is not clear how to turn off these warnings. Anyone know what the Android equivalent is to 

jsCodeLocation = [NSURL URLWithString:@"http://localhost:8081/index.ios.bundle?platform=ios&dev=false"];

in index.android.bundle file in the assets folder there is an entry

(function(global) {global.
    __DEV__=true;

set to false and all my issues went away

First of all, normally you should bundle your JS if you plan to run the app in production mode, e.g. by running some command like this:

node node_modules/react-native/local-cli/cli.js bundle --dev false --platform ios --entry-file ./index.ios.js --bundle-output ./ios/main.jsbundle

To answer your question, the android/src/main/java/com/YOUR_PROJECT_NAME/MainActivity.java file should contain something like this

/**
  * Returns whether dev mode should be enabled.
  * This enables e.g. the dev menu.
  */
  @Override
  protected boolean getUseDeveloperSupport() {
    return BuildConfig.DEBUG;
  }

Which you may change to

/**
  * Returns whether dev mode should be enabled.
  * This enables e.g. the dev menu.
  */
  @Override
  protected boolean getUseDeveloperSupport() {
    return false;
  }

Edit: fixed typo
