java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState while using FragmentTabHost

Question

I am trying create a tabbed activity using the below code

 public class FragmentTabs extends FragmentActivity { private FragmentTabHost mTabHost; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mTabHost = (FragmentTabHost) findViewById(android.R.id.tabhost); mTabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent); mTabHost.addTab(mTabHost.newTabSpec("simple").setIndicator("Simple"), SimpleFrag.class, null); mTabHost.addTab(mTabHost.newTabSpec("detailed").setIndicator("Detailed"), DetailedFrag.class, null); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.main, menu); return true; } } 

The code always shows java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState inside FragmentManager. I googled seveal times and goes through almos all the links. but i can't get any solution. Please help me because i'm stuck on this.
