使用NativeScript 8.6.5开发的新应用APK体积过大原因咨询

我用NativeScript 8.6.5开发的新应用APK体积达121MB，其中107MB来自lib文件夹，x86、x86_64、arm64-v8a和armeabi-v7a四个架构的libNativescript.so文件每个都超过20MB。应用仅包含少量组件，assets目录无图片文件，依赖也偏基础，但就算移除部分依赖，APK体积仍不低于90MB。

    },
    "projects": {
        "appname": {
            "root": "",

优化方案 #

1. 只打包必要的CPU架构 #

默认NativeScript会打包4种架构，但大部分安卓设备仅需arm64-v8a和armeabi-v7a，x86架构主要用于模拟器。在nativescript.config.ts中指定架构：

export default {
  // 其他配置
  android: {
    abiFilters: ['armeabi-v7a', 'arm64-v8a']
  }
}

此操作可直接减少两个.so文件的体积，预计节省40MB左右。

2. 启用Webpack生产环境压缩 #

确保构建时使用生产模式，Webpack会自动压缩代码与资源。执行构建命令：

ns build android --env.production

也可检查webpack.config.js确认压缩配置：

const { composePlugins, withNativescript } = require('@nativescript/webpack');
module.exports = composePlugins(withNativescript(), (config) => {
  if (config.mode === 'production') {
    config.optimization.minimize = true;
  }
  return config;
});

3. 移除非核心依赖 #

检查@nativescript/pdf、nativescript-ui-sidedrawer等插件，确认是否为必需项：

• 若侧边栏仅需基础功能，可替换为NativeScript原生RadSideDrawer或自行实现
• 若PDF功能非核心，暂时移除后观察体积变化

4. 切换为AAB格式构建 #

Android App Bundle（AAB）是Google推荐格式，用户下载时仅获取对应设备架构的文件，实际下载体积会大幅降低。构建命令：

ns build android --env.production --aab

5. 移除调试符号 #

生产构建时确保关闭调试符号，在nativescript.config.ts中配置：

export default {
  android: {
    debuggable: false,
    removeDebugSymbols: true
  }
}
