如何在Android Studio中压缩android项目

Question

我在android studio中创建了一个android应用程序，而我使用Kotlin作为编程语言。现在我的应用程序完成了，我想构建我的应用程序，但是构建应用程序后，请向我显示35mb的应用程序大小！！！我的[[可绘制文件夹大小为2mb，并且没有更大的文件，但是为什么我的应用程序大小为35mb？!!!

用于生成测试apk版本，我从Android Studio菜单中使用了[[Build-> Generate Signed Build / APK。

但是当使用java作为语言时，该大小为

7mb !!!

我使用了此依赖项：
