Ah, but perhaps you shouldn't.
First, AFAIK, TabActivity handles setup() for you.
Second, you called setup(), not setup(LocalActivityManager
activityGroup). My guess is that setup() wiped out the, er, setup that
TabActivity did. Since you need the activityGroup to handle Intent-based
tabs, your setup() call may be causing more harm than good.
For example, from the soon-to-be-released Version 1.9 of (*cough*) my
book, here's a TabActivity:
public class IntentTabDemo extends TabActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TabHost host=getTabHost();
host.addTab(host.newTabSpec("one")
.setIndicator("CW")
.setContent(new Intent(this, CWBrowser.class)));
host.addTab(host.newTabSpec("two")
.setIndicator("Android")
.setContent(new Intent(this,
AndroidBrowser.class)));
host.setCurrentTab(1);
}
}
(the host.setCurrentTab(1); line won't be in the book as I don't need
it, but I put it in there to confirm that it does indeed work)
Try commenting out your setup() call and see if things work.
