Android偏好特定權限請求

Question

只有當用戶啓用某個偏好時，纔有辦法請求特定權限嗎？

在我的情況下，我可以選擇與日曆同步來添加日期和設置提醒（據我所知，您不能在具有意圖的日曆中設置提醒）。顯然，我需要訪問日曆的權限，但只有在用戶啓用此選項時纔有效。我希望在用戶啓用首選項時請求權限，然後在未授予權限的情況下禁用該選項。

不幸的是，沒有辦法做到這一點。

No checks with the user are done while an application is running: it either was granted a particular permission when installed, and can use that feature as desired, or the permission was not granted and any attempt to use the feature will fail without prompting the user.
