在我将 Android Studio 更新到 3.3-rc01 并启用 R8 代码收缩后，生成签名的 APK 会出错。
它给出了以下proguard错误：
Error: ~/app/proguard-rules.pro, offset: 2613, line: 74, column: 7, Expected char '-' at ~/app/proguard-rules.pro:74:7
-dump class_files.txt
在 android studio 3.3-rc01 之前并且没有 R8 代码收缩它工作得非常好。
任何解决方法，或者我现在必须禁用 proguard 规则。
以下是我的 proguard-rules.pro 文件
