title: React Native Error undefined is not an object (evaluating 'navigator.userAgent.indexOf')
body: <p>We're getting this problem when creating an application with react-native init. </p>
  
  <p>The error is "undefined is not an object (evaluating 'navigator.userAgent.indexOf')"  When we do remote debugging in the browser, this doesn't happen. It runs fine in that situation. </p>
  
  <p>Also when we build it out as a standalone APK, the app immediately crashed.</p>
