如果将服务放在奥利奥的前台，是否需要设置唤醒锁？

Question

Do I need to set a wakelock if a service is put in the foreground in oreo?

Also, connected to the previous one:

The flow is like this, simplified for easier understanding:

MainActivity -> ContextCompat.startForegroundService of MyService-Intent -> in MyService: onStartCommand -> thread start -> in Thread: Thread.sleep

Sometimes, wenn Thread.sleep is longer than a certain time, the execution of the thread stops. Once I activate the phone again, the execution continues. How to constantly continue it?

Answer 1

发生这种情况的原因是，当用户在一段时间内不插拔设备并使其静止不动时，设备会进入打do模式，而屏幕关闭时，请参阅此更多详细信息https://developer.android.com/training/monitoring-device-state/doze -standby＃understand_app_standby ，一种替代方法是使用工作管理器以获取更多详细信息，请参见https://developer.android.com/topic/libraries/architecture/workmanager/basics
