我知道這聽起來很奇怪，但我創建了一個帶有活動和服務（啓動和綁定）的簡單計時器。只有當手機連接到PC時，android活動/服務纔有效
在活動中我還實施了在onStart和的onStop只是記錄消息（Log.d（TAG，「活動啓動/停止」）。
事實是，如果手機連接到PC的一切似乎我可以啓動計時器，暫停它，修改並重新啓動它，打開其他應用程序，它會繼續在後臺工作，我可以回想起來，並且我看到實際的倒計時正在進行，如果完成，我可以從一個通知，並停止振鈴等等等
如果手機它從PC分離，它的工作原理就像沒有服務，所以活動運行，如果我按主頁按鈕它會在背景和保持工作國王停了幾分鐘。
我可以在「正在運行的應用程序」中看到該進程，如果我記得它從暫停點重新開始的活動。也就是說，我設置了10分鐘，我點擊開始，然後點擊主頁按鈕。 2-3分鐘後停止工作，如果我記得活動從8-7分鐘繼續倒計時... ...
任何想法？

我不認爲你需要的定時器本身。它只是一個CountDownTimer，它可以更新小時/分鐘/秒的速度，並在onFinish播放聲音並創建通知。
當你說「連接到PC」時，你的意思是說你有一個調試器運行？ 「連接到PC」究竟是什麼意思？ – 2013-03-12 14:15:15
發佈您的代碼和堆棧跟蹤... – 2013-03-12 14:29:51
添加了代碼。 @DavidWasser嗯我有一個調試器？我正在使用eclipse。當然，我沒有設置任何調試器。月食會自動做些什麼嗎？ – Segolas 2013-03-12 14:39:31
