发布 apk 中的 Firebase IllegalAccessException

Question

我在 firebase 项目控制台中为调试和发布密钥库添加了 SHA1。我还通过应用程序中的 google-services.json 文件进行了更新。调试 apk 工作正常并访问 firebase 的所有实时数据库，但是当我构建发布 apk 时，我在访问 Firebase 数据库时遇到以下异常。

Answer 1

你有proguard-rules.pro吗？如果您使用了该文件，请检查 proguard for firebase。

Answer 2

ViewHolder 类应该是 public 而不是私有的或受保护的。是因为proguard.
