當應用程序完全關閉時，我的服務不工作

Question

我知道這個問題有很多問題，我幾乎看到所有問題，但我無法解決我的問題。我有一個使用本地廣播管理器調用主要活動的服務，我從該服務獲得一些價值，然後將它們放入字符串併發送到需要使用它們的其他服務。這些服務之一被稱爲本地廣播，但其中兩個在按鈕監聽器中，我使用警報管理器每隔1分鐘重複運行它們，同時我在第一個服務中使用satrtforeground（）調用主要活動，但在某些設備中奇怪地使用設備屏幕下車或用戶從後臺（從堆棧）清除應用程序不起作用。我希望你能幫助我，謝謝

public static final String Service = ServiceURL.class.getName() + "LocationBroadcast";

Answer 1

確保你是不是退出時結束應用程序的進程。使用

finishAffinity(); 

退出應用程序。

Answer 2

它取決於設備的型號。如果您從應用程序堆棧中刪除應用程序，不同設備的行爲會有所不同

某些設備可能會停止應用程序的進程，並且不會啓動任何一個警報管理器，但另一個設備只會關閉活動，但進程仍處於活動狀態。
