Is there a Tutorial on Running Android, iOS in background?

Questions & Answers

I been trying to find a way to run Unity App in the background on the Android and the iOS device.
It looks like the best way to do this is to run a Android/iOS service to do this, but everything I found wasn’t in a good step by step tutorial.

Can anyone point me in the correct direction on this?
