I’m trying to load an activity into a tab via an activity group but the activity isn’t loading which culminates in an illegalStateException error:

java code which reads the xml file containing the tabhost and tabwidget controls:
public class tabs extends Activity{
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tabmain);
TabHost tabs=(TabHost)findViewById(R.id.tabhost);
tabs.setup();
TabHost.TabSpec spec=tabs.newTabSpec("tag1");
spec.setContent(R.id.tab1);
spec.setIndicator("tab1");
tabs.addTab(spec);
spec=tabs.newTabSpec("tag2");
spec.setContent(R.id.tab2);
spec.setIndicator("tab2");
tabs.addTab(spec);
spec=tabs.newTabSpec("tag3");
spec.setIndicator("Favourites", getResources().getDrawable(R.drawable.favourites_star));
spec.setContent(new Intent(this,RadioAppActivityGroup.class).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));
tabs.addTab(spec);
}
private class RadioAppActivityGroup extends ActivityGroup{
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
View view = getLocalActivityManager().startActivity("radiotabs", new
Intent(this, favourites.class).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)).getDecorView();
this.setContentView(view);
}
}
}
xml code containg the tabhost and layout controls:
