JavaMail問題自動發送

我目前正試圖讓AlarmReceiver在由DatePicker/TimePicker觸發時發送電子郵件。現在，這已經成功地發送推送通知到移動設備。我也知道SendMail方法在不同的項目中工作。JavaMail問題自動發送

這應該是工作，但我看不到觸發SendMail方法一旦AlarmReceiver類被調用的代碼的任何問題？

任何幫助，將不勝感激！謝謝！

Alarm.java

廣播接收機執行可能會很快。

更好的是你應該啓動一個發送電子郵件的意圖服務。

感謝您的回覆。那麼這個執行可能太快了？當報警觸發時，我希望電子郵件是自動的，是不是可以通過這種方式來完成？ OnClick適用於單獨項目中的此方法，並且電子郵件會立即發送。 – ZenoX

我的意思是說，而不是使用AsyncTask，您可以使用將在後臺進程中運行的Intent服務，但AsyncTask可能不會。 – albeee

啊，我看到了，我還是新來的java和不確定如何更改此方法使用意圖服務，而不是AsyncTask？感謝您的幫助！ – ZenoX
