CodePush + Push Notifications for A/B Testing

      AsyncStorage.setItem('deploymentKey', deploymentKey);
      // You may also want to removeItem from asyncStorage to clear the A/B test and revert to original version of the app. 
    }

    }
    else {
      // Sometimes the push callback is received shortly before the app is fully active in the foreground.
      // Since we store the deployment key in AsyncStorage, codepush sync will be called when the app starts again, and the A/B test will run
