There is blank screen after publish app in ejected expo project

I’m new Expo and I have a issue for creating standalone app.
I have Expo project and after some time have need to use native code. So I ejected my expo project using the command expo eject.

After ejecting, I added native code and app worked well.

Finally for submitting app to both app store, I published expo app using expo publish.
After that I have blank screen. app was running but doesn’t show anything.
Anyone who know this issue advance me.
Following is my app.json file:

“expo”: {
“name”: “neighborhood”,
“description”: “This project is really great.”,
“slug”: “neighborhood”,
“privacy”: “public”,
“sdkVersion”: “30.0.0”,
“platforms”: [
“version”: “1.0.0”,
“orientation”: “portrait”,
“icon”: “./src/assets/images/icon.png”,
“notification”: {
“icon”: “./src/assets/images/notification_icon.png”,
“color”: “#000000
“updates”: {
“fallbackToCacheTimeout”: 0
“assetBundlePatterns”: [
“ios”: {
“supportsTablet”: true,
“bundleIdentifier”: "
“publishBundlePath”: “ios/neighborhood/Supporting/shell-app.bundle”,
“publishManifestPath”: “ios/neighborhood/Supporting/shell-app-manifest.json”
“android”: {
“package”: "
“publishBundlePath”: “android/app/src/main/assets/shell-app.bundle”,
“publishManifestPath”: “android/app/src/main/assets/shell-app-manifest.json”
“isDetached”: true,
“detach”: {
“iosExpoViewUrl”: “”,
“androidExpoViewUrl”: “
“scheme”: “expe0dee74a172e495fbe7bdc05832274ac”

And follow is App.js file:

import React, {Component} from ‘react’;
import { StyleSheet, Text, View, Navigator } from ‘react-native’;

import {SafeAreaView, createStackNavigator, createSwitchNavigator} from ‘react-navigation’;

import SignIn from ‘./src/pages/SignIn’;
import CreateProfile from ‘./src/pages/CreateProfile’;
import Home from ‘./src/pages/Home’;
import CreateNotification from ‘./src/pages/CreateNotification’;

const Navigation = createStackNavigator(
SignIn: {screen: SignIn},
CreateProfile: {screen: CreateProfile},
Home: {screen: Home},
CreateNotification: {screen: CreateNotification},



export default Navigation;

I’m very happy to hear your advance.


in .expo folder
and in settings.json
try this
“dev”: false,
“minify”: true
instead of this
“dev”: true,
“minify”: false

Hi, fahadtalpur

Thank you very much for your reply.

But my setting.json is following originally.
“hostType”: “lan”,
“lanType”: “ip”,
“dev”: false,
“minify”: true,
“urlRandomness”: “84-vif”

And app working is normal. Only one thing is doesn’t show view. So only show blank screen.

So I mean for example, if I add alert(“test alert”) in the componentDidMount() function of SingnIn.js(the first screen of navigator), then app shows the alert. but no displaying any view, only show black screen.
How can I do then?
I’m very happy to hear your advance.


the best way is that now you have to download the new project eject the empty project then copy the code, for sure it will work
