[android-developers] Tab Layout not working

Hi,

I am using the Tab Layout almost copied from the example provided. But
it's not working:

public class TabHolder extends TabActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

setContentView(R.layout.main);

Resources res = getResources(); // Resource object to get
Drawables
TabHost tabHost = getTabHost(); // The activity TabHost
TabHost.TabSpec spec; // Resusable TabSpec for each tab
Intent intent; // Reusable Intent for each tab

// Create an Intent to launch an Activity for the tab (to be
reused)
intent = new Intent().setClass(this, ArtistsActivity.class);

// Initialize a TabSpec for each tab and add it to the TabHost
spec = tabHost.newTabSpec("artists").setIndicator("Artists",
res.getDrawable(R.drawable.ic_tab_info))
.setContent(intent);

// ok up to here
tabHost.addTab(spec); // barfs right here **************

// Do the same for the other tabs
intent = new Intent().setClass(this,
MessagEaseSettings.class);
spec = tabHost.newTabSpec("settings").setIndicator("Settings",
res.getDrawable(R.drawable.ic_tab_settings))
.setContent(intent);
tabHost.addTab(spec);

intent = new Intent().setClass(this, SongsActivity.class);
spec = tabHost.newTabSpec("how").setIndicator("How",
res.getDrawable(R.drawable.ic_tab_how))
.setContent(intent);
tabHost.addTab(spec);

tabHost.setCurrentTab(2);
}

}

seems that the problem happens when it adds the spec:

tabHost.addTab(spec);

But there is not much to this:

intent = new Intent().setClass(this, ArtistsActivity.class);

// Initialize a TabSpec for each tab and add it to the TabHost
spec = tabHost.newTabSpec("artists").setIndicator("Artists",
res.getDrawable(R.drawable.ic_tab_info))
.setContent(intent);

the activity (ArtistsActivity) exists and passes Eclipse's strict
checks.

the strings "artists" and "Artists" should not matter, and they are
taken from the exmple.

and the drawalbe.ic.tab.info does exist, exactly as the example
requires it:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- When selected, use grey -->
<item android:drawable="@drawable/tab_info_gray"
android:state_selected="true" />
<!-- When not selected, use white-->
<item android:drawable="@drawable/tab_info_white" />
</selector>

Can anyone give me a hint as to where to look for? Any help is much
appreciated.

Best,

Saied
