React-Native安卓设备无法从API获取数据问题求助

问题情况 #

我在安卓设备上从API获取数据时遇到问题，要么无法获取数据，要么出现超时错误。各平台测试结果如下：

• Snack Expo（Web）：测试通过，可成功获取数据
• Expo（本地Web端）：测试通过，可成功获取数据
• Expo（安卓模拟器）：加载耗时极长，未获取到数据，测试失败
• Expo GO（真机）：测试失败，报错信息为Uncaught Error: java.net.ConnectException: Failed to connect to /ip

使用版本 #

• "expo": "~48.0.15"
• "react": "18.2.0"
• "react-native": "0.71.8"

代码示例 #

App组件代码 #

import React, { useEffect, useState } from 'react';
import { View, Text, FlatList } from 'react-native';

export default function Test2() {
  const [data, setData] = useState([]);

  useEffect(() => {
    fetchData();
  }, []);

  const fetchData = () => {
    console.log("start");
    fetch('https://646ee64209ff19b120864a07.mockapi.io/users')
      .then(response => response.json())
      .then(data => {
        console.log("data:", data);
        setData(data);
      })
      .catch(error => {
        console.error(error);
      })
      .finally(() => {
        console.log("end");
      });
  };

  return (
    <View>
      <FlatList
        data={data}
        renderItem={({ item }) => (
          <View>
            <Text>Id user: {item.id}</Text>
            <Text>Name user: {item.name}</Text>
            <Text>-------------------------</Text>
          </View>
        )}
        keyExtractor={item => item.id}
      />
    </View>
  );
}

App.Json配置 #

{
  "expo": {
    "name": "MyApp",
    "slug": "MyApp",
    "version": "1.0.0",
    "orientation": "portrait",
    "icon": "./assets/icon.png",
    "userInterfaceStyle": "light",
    "splash": {
      "image": "./assets/splash.png",
      "resizeMode": "contain",
      "backgroundColor": "#ffffff"
    },
    "assetBundlePatterns": [
      "**/*"
    ],
    "ios": {
      "supportsTablet": true
    },
    "android": {
      "adaptiveIcon": {
        "foregroundImage": "./assets/adaptive-icon.png",
        "backgroundColor": "#ffffff"
      }
    },
    "web": {
      "favicon": "./assets/favicon.png"
    }
  }
}

已尝试操作 #

• 检查网络：设备网络连接正常
• 检查API返回：JSON数据格式无问题
