Apps HelloTabWidget Tutorial Problems

[aSystemOverloa]

I've spent a while going through the posts on here, stack overflow and elsewhere about this, but can't seem to get the HelloTabWidget tutorial to work.

As below, it won't run, say it has errors [AlbumsActivity cannot be resolved into a type.] and suggests adding [import superiorxc.examples.AlbumsActivity.AlbumsActivity;] for each Albums, Songs and ArtistsActivity, but this causes a ForceClosure when it runs (ERROR: [01-07 18:15:03.230: E/AndroidRuntime(326): java.lang.RuntimeException: Unable to start activity ComponentInfo{superiorxc.examples.hellotabwidget/superiorxc.examples.hellotabwidget.HelloTabWidgetActivity}: android.content.ActivityNotFoundException: Unable to find explicit activity class {superiorxc.examples.hellotabwidget/superiorxc.examples.ArtistsActivity.ArtistsActivity}; have you declared this activity in your AndroidManifest.xml?]).

Would appreciate any feedback:

HelloTabWidget.java

package superiorxc.examples.hellotabwidget;

import android.app.TabActivity;
import android.content.Intent;
import android.content.res.Resources;
import android.os.Bundle;
import android.widget.TabHost;

public class HelloTabWidgetActivity extends TabActivity {
    /** Called when the activity is first created. */
    
    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_artists))
                      .setContent(intent);
        tabHost.addTab(spec);

        // Do the same for the other tabs
        intent = new Intent().setClass(this, AlbumsActivity.class);
        spec = tabHost.newTabSpec("albums").setIndicator("Albums",
                          res.getDrawable(R.drawable.ic_tab_albums))
                      .setContent(intent);
        tabHost.addTab(spec);

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

        tabHost.setCurrentTab(2);
    }
}

AlbumsActivity.java (+ ArtistsACtivity, SongsACtivity)

package superiorxc.examples.AlbumsActivity;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class AlbumsActivity extends Activity {
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        TextView textview = new TextView(this);
        textview.setText("This is the Albums tab");
        setContentView(textview);
    }
}

HelloTabWidget Manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="superiorxc.examples.hellotabwidget"
    android:versionCode="1"

    <application

        <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
        </activity>
        <activity android:name=".AlbumsActivity"
            android:label="@string/app_name"
            android:theme="@android:style/Theme.NoTitleBar">
         </activity>
         <activity android:name=".ArtistsActivity"
            android:label="@string/app_name"
            android:theme="@android:style/Theme.NoTitleBar">
            </activity>
         <activity android:name=".SongsActivity"
             android:label="@string/app_name"
            android:theme="@android:style/Theme.NoTitleBar">
        </activity>
    </application>
</manifest>
