So what exactly is your question? Have you single-stepped through the code using the debugger? Have you considered checking return values from function calls, or maybe surrounding the code with a

Hello, I had similar problem. Please see my example: 1) Xml file (note android.support.v4 is used):
- Java file for Activity:
MainActivity extends FragmentActivity
implements YourFirstFragment.OnFragmentInteractionListener, YourSecondFragment.OnFragmentInteractionListener{
private FragmentTabHost _yourTabHost;protected void onCreate(Bundle savedInstanceState)
{
_yourTabHost =(FragmentTabHost)findViewById(android.R.id.tabhost);
_yourTabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent);_yourTabHost.addTab(_mTabHost.newTabSpec("first_fragment").setIndicator("NameOnTab"), YourFirstFragment.class, null);
_yourTabHost.addTab(_mTabHost.newTabSpec("second_fragment").setIndicator("NameOnTab"), YourSecondFragment.class, null);
}
}Hope this will help somehow.
