Question

我想仅对项目中的单个类文件应用proguard工具，该项目还包含其他库。那么我怎样才能做到这一点。任何形式的帮助将不胜感激。

ProGuard会尝试修剪/混淆所有内容，除非它是由规则明确保留的，所以你正在寻找的技巧是创建一个规则来告诉它保留除特定类之外的所有内容：

<!DOCTYPE html>
<html>
<head>

  <link rel="stylesheet" href="styles.css">
   <link href="https://fonts.googleapis.com/css?family=Montserrat" rel="stylesheet">

    background-attachment: fixed;

这绝对可以满足您的要求，但我也想知道这首先是否有用。 ProGuard不仅提供代码混淆 - 它还删除了未使用的代码以使APK更小，因此我们应该尽量将其应用于尽可能多的事情。

Proguard仅支持单个java文件--Android
