Question

我已经花了两天时间让这个工作起来但是我不能，我一直得到这个例外com.parse.ParseRequest$ParseRequestException: invalid session token。我不是一个经验丰富的Android开发者，这是我第一次使用解析器，所以如果你能发布一个详细的答案，我会很感激。

我在这篇文章中尝试过这个答案，但我一直得到同样的例外 com.parse.ParseRequest$ParseRequestException: invalid session token

Answer 1

您需要在Login \ Signup视图控制器中注销用户。

在viewDidLoad中尝试：

ParseUser.getCurrentUser().logOut();

Answer 2

为了将来的参考，我所要做的就是从模拟器中卸载应用程序而不是再次运行它，问题就解决了。
