Android Question Detect backround service from my app

[gvoulg]

I have two different apps
My first app is a service (noUI) to run as sticky to log GPS coordinates all day.
When I start my main app I want to start this sticky service (first app).
I know how to do it.

Dim in As Intent
        Dim pm As PackageManager
        in = pm.GetApplicationIntent("firstapp")
        If in.IsInitialized Then StartActivity(in)

.
The question is how do I know if it is already running so I don't have to start it again the
next time I start the main app?

In fact I don't want to exchange values or communicate between the two apps.
I just want to know if the first app ( a sticky service ) is already running.
I can't see the answer to this in this tutorial .
Am I missing something?

Send a intent to the other app. When the other app receives such an intent it responds with another intent.
At the end you did a Handshake and know it is alive because it responds.
