Answer 2

in your activity class try this and in my app is working just fine.

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);   
        }

Hope it helps you
