Answer 1

I faced the same issue in my OnePlus3 for my app. Then I noticed these lines in logcat, every time my app and Foreground service were killed:

10-12 18:30:40.644  1439  1519 I OHPD    : [BgDetect]force stop com.mycompany.MyAndroidApp (uid 10905) level 0

Then searching the internet for the keywords 'OHPD : [BgDetect]chkExcessCpu level: 1 doKills: true' took me to this SO answer:

Prevent background service from being killed due to "detect excessive cpu on forked process"

As suggested in that answer and the GitHub issue, Locking / Pinning my app prevented Oxygen OS from killing my app (MainActivity and Forground Service).
