This is a sample app for testing the Hover React Native Bridge. See the README in that project for including the Hover React SDK in your React Native app.
To get started with this app use this guide https://facebook.github.io/react-native/docs/getting-started.html. Once everything is set up you can test on a real device by running the following:
react-native start
adb reverse tcp:8081 tcp:8081
react-native run-android
The reverse command should only be neccessary if you are attempting to run on a real device from within android studio.
