Android :: Get 2 Sessions Registered In Localytics Per App-launch?

I am implementing Localytics.com useage statistics in my Android app.
I am still just testing.

I note that just starting my app and then immediately exiting will register two sessions (as they are called by Localytics) in the live statistics.

I have followed the guidelines in Android Integration.

My app consists of a main Class of the TabActivity type. This TabActivity holds two tabs in which I display two other activities.

Like this:

CODE:..............

I instantiate the Localytics object in all three Activities like this:

CODE:............

So, the above code lines are repeated in each of the three Activities. In the TabHost Activity (only in this Activity) I then follow the instantiation with a this.localyticsSession.upload();

And then (only in the TabHost Activity) I have these to finish things off:

CODE:.......

How to make my code generate just one session per app-launch?
