我使用Google-API從Google-Calender中獲取未讀電子郵件和一些事件的數量。我使用了Google的Quick-Start示例代碼，它工作正常（如果未設置，請求範圍權限等）。所以我將它形成了一個服務和一個授權活動，供用戶更改他們的賬戶。我的問題是，用戶不會被要求授權了。該應用程序仍然使用正確的帳戶，如果我選擇一個授權給我的應用程序的帳戶，它仍然有效，但如果我選擇一個新的帳戶，則不會顯示授權表單。要求在Google API中授權
谷歌AuthUtil錯誤：
09-19 13:13:54.114: D/DEBUG_TEST(7072): ERROR: UserRecoverableErrorNeedPermission
這裏是我的活動，改變了賬戶。每次用戶選擇一個Google帳戶時，靜態變量「gAccountDaten」（GoogleAccountCredential對象）得到更新。

謝謝， J. Doe的）
這個錯誤很簡單，因爲你需要處理這個異常與捕捉（UserRecoverableAuthIOException E）{ startActivityForResult（e.getIntent（），REQUEST_AUTHORIZATION ）; } ... – PN10
我在我的Auth-Activity中無法使用e.getIntent（）。有沒有其他的方法來檢索它？ –
好像你已經把它整理出來了...不是嗎？ – PN10
