有四个文件，分别是Dashboard.java，VerifyPhone.java，RegisterPhone.java和SetupProfile.java，我能够成功执行OTP身份验证并将其移至Setup Profile Activity，然后将应用程序移至Dashboard.java

问题是，如果我退出以Dashboard.java开头的应用程序，它将无法继续进行配置文件设置活动。每当我执行登录时，它都会直接登录到信息中心，我希望该应用在打开应用后恢复未完成的帐户设置

Answer 1

尝试理解您的代码（需要改进如何在StackOverflow中编写代码）之后，我认为问题是因为您只是在应用程序退出时忘记了注销。

即使您退出应用程序，Firebase也会保持您的用户登录状态。这就是为什么在您的RegisterActivity中，结果始终会实现的原因，因为FirebaseUser中始终有一个FirebaseAuth。解决方法是：您必须确保他们重新输入应用程序后退出。

建议

您可以在每次活动被销毁时（或每次用户打开应用程序时）注销。确保它们总是从新开始。

无法保存Firebase活动状态
