無法啓動服務意圖：找不到

我使用AlarmManager在每個間隔調用一個活動，但是間隔必須可以更改。該活動只是另一個我已更改爲pendingIntent的函數。調用類如下所示，它也是主類。被調用的類顯示在調用類之後。最後，清單文件可能包含錯誤的來源。無法啓動服務意圖：找不到

true..However，我也跟着使用toast_test作爲的PendingIntent的例子，並與AlarmManager的getSystemService啓動它。我可以開始任何活動作爲意圖和使用AlarmManager？ – user301

我不清楚你在問什麼，但意圖就像活動之間傳遞的消息。您可以通過發送意向開始活動。您只需在清單文件中針對您的活動編寫intent過濾器。 – Vivek
