title: Icon in Tab is not showing up
body: <p>I'm starting with Android and when I try to do a TabHost with an icon and a text. Only the text is visible, if I left the text in blank it is possible to see the icon. I want to see both on screen. </p>
  
  <p>Can somebody give me advice?</p>
  
  <pre><code>public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);
  
  Usuario usu = new Usuario();
  usu.nombre = "fsdf";
  lista.add(usu);
  
  adaptador = new AdaptadorCelda(this,lista);
  ListView lstView = (ListView)findViewById(R.id.lista);
  lstView.setAdapter(adaptador);
  
  Button btn = (Button)findViewById(R.id.btnSalva);
  
  btn.setOnClickListener(onSave);
  
  
  
  Resources res = getResources();
  
  TabHost tabs=(TabHost)findViewById(R.id.tabhost);
  tabs.setup();
  
  TabHost.TabSpec spec=tabs.newTabSpec("mitab1");
  spec.setContent(R.id.tab1);
  spec.setIndicator("",res.getDrawable(android.R.drawable.ic_menu_rotate));
  
  
  tabs.addTab(spec);
  
  spec=tabs.newTabSpec("mitab2");
  spec.setContent(R.id.tab2);
  spec.setIndicator("ddd",
         res.getDrawable(android.R.drawable.presence_invisible));
  tabs.addTab(spec);
  
  tabs.setCurrentTab(0);
  
  spec.setIndicator("",res.getDrawable(android.R.drawable.ic_menu_rotate)) In this case icon appears.
  
  spec.setIndicator("ddd",
         res.getDrawable(android.R.drawable.presence_invisible));
