在minifyEnabled为true之后，使用google for android登录并不在发布apk中工作

Question

我做了一整天的研究。由于发布SHA1，大多数人都面临着问题，但我已经使用所有方法（命令行和Android工作室）进行了检查。我正在获得相同的发布哈希密钥，如果我在发布版本中使minifyEnabled为false，它正在工作。

如果我将minifyEnabled设为true以混淆文件，则谷歌登录无效。

这是我的proguard文件

非常感谢任何帮助，花了一整天时间来解决这个问题!!

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模型类以便保存
