Hello,
You have several options depending how you want it to be :
- if only closing an Activity : Activity.Finish
- if closing ALL the whole app, be sure to previously stop any service, timer, background task and than ExitApplication (if you don't stop anything, the System would produce some errors). Use it with caution
- Stopping a service is done using StopService(ServiceName)
Generally speaking, depending on your Workflow, it is possible to simulate any restart without having to stop anything. In case it could be help
Edit: it works only for Your application, of course.
