Please don't do that.
First, it's not possible:
Make sure you aren't calling startActivity() anywhere, such as in
onCreate().
Look at the log (adb logcat) and event log (adb logcat -b events) to see
what the system is saying about launching and handling activities.
Please don't use singleTask or singleInstance to fix such problems, they are
Starting a service doesn't have anything to do with the activity stack. It
is only needed if you actually must have a service running even after the
user leaves your app. (And of course you must have a good plan for how you
will stop the service, so it doesn't get left running forever.)
