Context.startForegroundService() did not then call Service.startForeground()

What problem do you get?
Context.startForegroundService() did not then call Service.startForeground(): ServiceRecord{ad3cfbc u0 /com.liulishuo.filedownloader.services.FileDownloadService$SharedMainProcessService}

Which version of FileDownloader are you using when you produce such problem?
1.7.7

How to reproduce such problem?
When OS >= Oreo and App is still in foreground

---
看到之前有issue提到这个问题，并且看源码已经解决，但是1.7.7上又遇到这个问题，不知道有没有人遇到同样

Start by reproducing the report on Android Oreo or newer with FileDownloader 1.7.7 while the app is foregrounded. Trace FileDownloadService$SharedMainProcessService and the foreground-service lifecycle; done means the reported Context.startForegroundService() error no longer occurs in that scenario.
