解决方案 #

• 安装并配置expo-asset插件
  1. 安装依赖：

     npx expo install expo-asset
     

  2. 修改babel.config.js，添加插件：

     module.exports = {
       presets: ['module:metro-react-native-babel-preset'],
       plugins: ['expo-asset/babel'],
     };
     

• 配置Metro以处理Expo资产
  在metro.config.js中更新配置，确保资产解析正确：

  const { getDefaultConfig } = require('expo/metro-config');
  const config = getDefaultConfig(__dirname);
  
  // 根据你的项目资产类型添加对应的扩展名
  config.resolver.assetExts.push('db', 'mp3', 'ttf', 'png');
  module.exports = config;
  

• 清理构建缓存
  执行命令清除旧缓存：

  npx react-native clean
  cd android && ./gradlew clean
  

• 重新构建Release包
  清理完成后重新执行构建：

  cd android && ./gradlew assembleRelease
