android tabview application error

I trying to get the tabview app to work, its working fine in the eclipse emulator, but when trying to install in the device its creating four application each of different activity, that is used in the tab application, did this kind of problem ever occurred to anyone.

some of the code from main activity:

super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Resources res = getResources(); // Resource object to get Drawables   
TabHost tabHost = getTabHost(); // The activity TabHost   
TabHost.TabSpec spec;  // Reusable 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, ArtistActivity.class);   
spec = tabHost.newTabSpec("main").setIndicator("Main", res.getDrawable(R.drawable.ic_tab_main)).setContent(intent);   
tabHost.addTab(spec);    
intent = new Intent().setClass(this, AlbumActivity.class);   
spec = tabHost.newTabSpec("camera").setIndicator("Camera", res.getDrawable(R.drawable.ic_tab_camera)).setContent(intent);   
tabHost.addTab(spec);   
intent = new Intent().setClass(this, SongsActivity.class);   
spec = tabHost.newTabSpec("livemap").setIndicator("Live Map", res.getDrawable(R.drawable.ic_tab_livemap)).setContent(intent);   
tabHost.addTab(spec);   
tabHost.setCurrentTab(0);

I am sure there is an issue (not an issue, but a mistake) inside the AndroidManifest.xml file. Mistake is that you have defined all 4 activity as a Launcher activity, instead of that you just have to define only one activity as a Launcher activity.

For example:

<activity android:name=".MainActivity">

          <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
   </activity>

And remove MAIN and LAUNCHER from other activities.
