Your theory appears to be correct. addTab() calls setCurrentTab(0) when
you add the first tab, and that will cause that tab's activity to be
launched.

Frankly, I have yet to figure out what that sex appeal is of putting
activities in tabs. AFAICT, it results in more fragile code. If you need
the same things to be in a tab *and* in a separate activity, reuse the
inflation and view logic between a standalone activity and just using the
View for a tab's contents. All the tabs-as-activities code seems to do is
launch the activity, then rip the root view out of that activity and put
it in the tab.
So, if you really want control over what happens when, I'd skip the
tabs-as-activities approach, and just put ordinary views in the tabs.
But, that's just me.
