That's a trifle unusual. It would make sense, as a user-chosen option,
if the app is an alarm clock. Generally, services should not be
starting activities, since you don't know what the user is doing at
the time, and the user may not appreciate the interruption.

The way you would do that is via the binding pattern, which is not
available to you if you are using AlarmManager. Again, if you are
using AlarmManager, you have no idea whether your activity even
exists, let alone is in the foreground.
You may get more help if you explain what it is that you are trying to build.
