我使用Expo XDE创建了一个项目.我检查了这个
Can’t load expo app: Something went wrong,但我已经启用了“绘制其他应用程序”.当我扫描这个二维码时,它工作
https://expo.io/@ajaysaini/first-proj但是当我在Android设备上从XDE运行它时它没有.
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.我尝试多次在XDE中重启,但它没有帮助我.

任何人都可以帮我解决问题吗?
解决方法
您最好打开XDE Client并启用开发模式.然后,单击灰色齿轮以使主机> LAN(局域网 – 这意味着通过WiFi与真实设备共享包).
Localhost选项可能也可以,但根据Expo Debugging docs:
If you are using LAN,make sure your device is on the same wifi network as your development machine. This may not work on some public networks. localhost will not work for iOS unless you are in the simulator,and it only works on Android if your device is connected to your machine via USB.
此外,这是我几个月前写的一个视觉信息性答案,也可能有所帮助:How do I run an app on a real iOS device using Expo?
