I have developed an app using React-native, now i converted to expo using exp convert. I did all the changes to folder which is need (by following steps in expo-next-steps.txt) but when i run project on expo XDE, i am getting error like Error: Missing app.json. How to solve this problem? and i used local push notification in react-native app. But in project structure there is file called app.json, still getting this error. i am new to expo, anyone please help me out.

The expo XDK looks for the expo SDK version in the app.json file. Thus, your app.json should look something like : 

{
  "name": "MyAPP",
  "displayName": "MyAPP",
  "expo": {
  "sdkVersion": "18.0.0"
 }
}

Replace the "18.0.0" with your SDK version. Such error emerges when you create the app using 

react-native init

instead of 

create-react-native-app

I perceive this as one of the reasons. There may be more such explanations to such occurrences.Happy coding!

I deleted the app.json, restarted and it works in my setup. You might rename it simply to app.json.orig
