我正在開發一個應用程序，並且我被封鎖在一件簡單的事情中。android兩次調用相同的對話框
在我的活動，我表明問一個郵件地址和激活對話框（AlertDialog.Builder）。這兩個字段用Rest API檢查。
如果激活碼是錯了，我重新開始活動（有意向），我再次顯示該對話框。
我不明白爲什麼，如果我錯了激活碼的第一次，第二次正確出現的對話框中，但是當我點擊「提交」，應用程序不運行REST調用和返回總是「無效憑證」，就像它會提醒舊的「狀態」一樣。
相反，如果我運行應用程序，我把正確的憑據，一切正常。
有什麼想法？
源代碼：

重要的一點是在 「情況1001」，錯誤之後。 我試圖完成（）和所有要刪除的活動的舊實例的方法......
很難建議沒有您的源代碼的東西。 – eleven
@eleven這裏的源代碼 – hteo
爲什麼你要重新啓動錯誤憑證的活動，爲什麼不重新彈出對話框？ – AndroidGeek
