SignUp活動Android上的會話令牌無效（解析後端）

Question

我已經花了2天才能使這個工作，但我不能，我不斷收到這個異常com.parse.ParseRequest$ParseRequestException: invalid session token。 我不是一個有經驗的android開發者，這是我第一次解析，所以如果你能發佈詳細的答案，我會很感激。

我試圖在這個職位的答案，但我一直得到相同的異常 com.parse.ParseRequest$ParseRequestException: invalid session token

Answer 1

以供將來參考我不得不做的是從模擬器卸載應用程序比再次運行和問題得到解決。

Answer 2

您需要在Login \ Signup視圖控制器中註銷用戶。

在viewDidLoad中試試這個：

ParseUser.getCurrentUser().logOut();
