[android-developers] Activity/Intents inTabs

Developers. I am a newbie to Android but a seasoned developer in UI,
Java , and ECLIPSE.

I am trying to do something I believe is very simple yet I am
struggling. I have two tabs, A & B. I want to put an Activity in
each tab. I want to have the 'B' Activity live inside 'A' so I can
access it within 'A'. 'A' has a clock and every second that passes I
need to update information in 'B', even if 'A' is not currently shown.

I put 'B' into the 2nd tab as follows:

TabSpec mapInfo=tabs.newTabSpec("tag3");
Intent intent = new Intent(this, MathleteMapActivity.class);
mapInfo.setContent(intent);
mapInfo.setIndicator("Course Map");
tabs.addTab(mapInfo);

I am totally confused on how to get the "MathleteMapActivity" Activity
from the Intent 'intent'. There appears no way to do this. Can
anyone please recommend a cleaner way to do this knowing what I am
trying to do?

Thanks in advance.

Chris
