Android 颤振-如何减少设备上的应用程序大小
我的应用程序包在谷歌PlayStore中的下载大小约为23MB： 但为什么安装后，磁盘上的应用程序大小会显著增加到83 MB 知道为什么会这样吗，因为： 1） Flatter的资产文件（图像、声音和字体）仅在11MB左右的项目上 2） 仅磁盘上颤振源代码（.dart）的大小1.4 MB 3） Android本机资源/图标（Res）仅约为800 KB 关于颤振的插件，我使用如下：Android 颤振-如何减少设备上的应用程序大小,android,gradle,flutter,dart,apk,Android,Gradle,Flutter,Dart,Apk,我的应用程序包在谷歌PlayStore中的下载大小约为23MB： 但为什么安装后，磁盘上的应用程序大小会显著增加到83 MB 知道为什么会这样吗，因为： 1） Flatter的资产文件（图像、声音和字体）仅在11MB左右的项目上 2） 仅磁盘上颤振源代码（.dart）的大小1.4 MB 3） Android本机资源/图标（Res）仅约为800 KB 关于颤振的插件，我使用如下： dependencies: flutter: sdk: flutter flutter_loca

除此之外，您还需要启用proguard以减小apk的大小，并防止应用程序反向工程。在颤振中 默认情况下，flatter不会混淆或缩小Android主机。如果您打算使用第三方Java、Kotlin或Android库，您可能希望减小APK的大小或保护该代码不受反向工程的影响 按照以下步骤在应用程序中启用progaud 步骤1：步骤1-配置Proguard 创建一个

应用程序也依赖于本机库，并且大多数本机库都是设备上可用的android框架库，因此它们不会捆绑在apk/aab中。但这些LIB将包含在odex文件中，因此在安装时会扩展其大小 问题：可能的预防措施是什么 回答： 如果库是为服务器或桌面设计的，那么它可以包含许多应用程序不需要的对象和方法。若要仅包含应用程序所需的库部分，您可以编辑库文件（如果许可证允许您修改库）。您还可以使用另一种移动友好库向应用程序添加特定功能 注意：代码收缩可以清除库中一些不必要的代码，但它可能无法删除一些大型内部依赖项 也请阅读这里提到的步骤
要生成应用程序包，请运行：
flutter build appbundle --target-platform android-arm,android-arm64
flutter build apk --target-platform android-arm,android-arm64 --split-per-abi
了解更多信息：使用以下命令
flutter build apk --split-per-abi
