如果我用AlarmManager安排警报（一PendintIntent应发），我怎么能确定报警后，取消了吗？我可以取消定于我的应用程序的所有报警？

If I use the AlarmManager to schedule an alarm (a PendintIntent which should be send), how can I identify that alarm later to cancel it? Can I cancel all alarms scheduled by my app?

推荐答案

您可能希望有一个仔细看看AlarmManager.cancel(PendingIntent操作） 功能。

You probably want to have a closer look at the AlarmManager.cancel(PendingIntent operation) function.
