android - 在 minifyEnabled true 后，使用 google for android 登录在发布的 apk 中不起作用

Question

我研究了一整天。由于发布 SHA1，大多数人都面临问题，但我已经使用所有方法(命令行和 Android studio)进行了检查。我得到了相同的发布哈希 key ，如果我在发布版本中将 minifyEnabled 设置为 false，它就可以工作。

如果我将 minifyEnabled 设置为 true 来混淆文件，则 google 登录将无法正常工作。

这是我的 proguard 文件

非常感谢任何帮助，在这个问题上花了一整天的时间!

经过2天的努力，我解决了。问题在于改造和模型类。

我们不应该允许重命名如此保留的模型类
