Android Question Watchdog for Kiosk Application

[Mike1970]

Hi everyone, I'm developing a Kiosk Application that must be ROBUST and STABLE.
I'm doing a lot of researches on the forum and beyond... but there are things that I do not like at all... (I hope I'm not understanding it correctly...)

I followed @Erel's tutorial about Kiosk Applications, and also him suggested creating a second application that acts as a watchdog for the actual app in this answer.
Then, thanks to the people the helped me in one of my latest posts I understood that I've to setup my project like this:

Questions

1. Is still possible to have foreground service on the watchdog app that has a periodic timer as suggested by Erel? since from this post it seems not possible anymore...
2. Is still this the best option nowadays to monitoring a second application to keep it always running in case of unhandled crashes?

Keep in mind that the watchdog app should always remain in background... the real app with which the users will interact is the "Actual App"

1. You can start a foreground service while the app is in the foreground (visible).
2. I think so.

I encountered a big problem trying this.
I described it here
