so I am facing small bit of so to call - exploit/bug. 因此，我面临这样的挑战-漏洞利用/错误。 I have an app which triggers activity and wakes up phone from lockscreen and shows alarm, all works fine sound works but there are few scenarios in which I have problem: If user clicks home button it just minimizes app and thats it, it remains running in background. 我有一个可触发活动并从锁屏唤醒电话并显示警报的应用程序，所有声音工作正常，但在少数情况下我有问题：如果用户单击“主页”按钮，它将应用程序最小化，仅此而已，它仍在运行背景。 If user locks screen, the alarm is silenced - if unlocked within 10 seconds it continues, if unlocked after 10 seconds it's minimized and runs in background. 如果用户锁定屏幕，则警报将静音-如果在10秒钟内将其解锁，警报将继续，如果在10秒钟后被解锁，则警报将最小化并在后台运行。

How would I go about fixing these? 我将如何解决这些问题？ what approach would you suggest? 您会建议哪种方法？ I assume alarm activity goes into onPause? 我认为警报活动进入了onPause吗？ if so I was thinking of making new Handler and wake up phone in 10 seconds in onPause method but wondering if there is any better approach? 如果是这样，我正在考虑使用onPause方法制作新的Handler并在10秒内唤醒电话，但想知道是否还有更好的方法？

I dont think post a Handler is a good idea, there is no grantee that your Activity dos not get destroyed by Android system, and then you Handler will not work. 我认为post a Handler不是一个好主意，没有被授予人认为您的Activity不会被Android系统destroyed ，然后您的Handler将无法工作。

I suggest to set a new Alarm (after 10 seconds) that run a Service/Broadcast in onPause() , you can send the time of setting the Alarm in the PindingIntent . 我建议在onPause()设置一个运行Service/Broadcast的新Alarm （10秒后onPause() ，您可以在PindingIntent发送设置Alarm的PindingIntent 。 get that time check it or cancel the Alarm . 得到那个时间检查它或取消Alarm 。
