title: React-Native run-android: The expo SDK requires Expo to run. It appears the native Expo modules are unavailable and this code is not running on Expo
body: <p>I developed a React Native application and tested it using Expo. When I finished, I tried to export the apk but I saw that it crash immediately after the execution. Then I tried to run "react-native run-android" and I see that the problem was something about Expo. The exact error is:
  "The expo SDK requires Expo to run. It appears the native Expo modules are unavailable and this code is not running on Expo". How can I use this app without Expo? What should I do to make it work?</p>
