无法加载exp://出问题了

问题描述

我已经使用Expo XDE创建了一个项目.我检查了此无法加载expo应用程序:出了点问题，但是我已经启用了在其他应用程序上绘图".当我扫描此文件时，它可以 https://expo.io/@ajaysaini/first-proj QR代码，但是当我在XDE的android设备上运行它时却没有.

I have created a project using Expo XDE. I checked this Can't load expo app: Something went wrong but I have already enabled "Draw over other apps". It works https://expo.io/@ajaysaini/first-proj when I scan this QR code but it doesn't when I run it on android device from XDE.

main.js

import Expo from 'expo';
import React from 'react';
import { StyleSheet, Text, View } from 'react-native';

class App extends React.Component {
  render() {
    return (
      <View style={styles.container}>
        <Text>Updating!</Text>
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: '#fff',
    alignItems: 'center',
    justifyContent: 'center',
  },
});

Expo.registerRootComponent(App);

当我在设备上运行它时，它在android设备上显示以下错误.我尝试了多次在XDE中重新启动，但对我没有帮助.

When I am running it on device it shows below error on android device. I tried restart in XDE multiple times but it didn't help me.

推荐答案

您最好打开XDE Client并启用开发模式.然后，点击灰色齿轮以创建 Host> LAN (局域网-意味着通过WiFi与实际设备共享软件包).

You better open XDE Client and enable development mode. Then, click on the gray cog to make Host > LAN (Local area network - which means sharing packages over WiFi with a real device).

Localhost选项也可以使用，但是根据 Expo Debugging文档:

Localhost option may work as well but according to Expo Debugging docs:
