android: add empty tab first and set content later -

in example below, there way add empty tab first , set content later when args value not null?

public class mainactivity extends fragmentactivity { private fragmenttabhost mtabhost;  @override protected void oncreate(bundle savedinstancestate) {      super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);      .........//more code      bundle args = new bundle();      args.putserializable("arguments", object);      ..................      mtabhost.addtab(mtabhost.newtabspec("tab1").setindicator("tab1"),         tab1fragment.class, args);     mtabhost.addtab(mtabhost.newtabspec("tab2").setindicator("tab2"),         tab2fragment.class, args);     mtabhost.addtab(mtabhost.newtabspec("tab3").setindicator("tab3"),         tab3fragment.class, args); } } 

as per android api documentation of fragmenttabhost, add tab when argue not null , use setup method
