add TabHost inside a TabHost :cannot be cast to android.support.v4.app.Fragment 5

Question

I'm trying to create a TabHost in ListView in a TabHost, and I get the cast error.

enter code here  Process: com.example.vaidenv2, PID: 30623
java.lang.ClassCastException: com.example.vaidenv2.FQAGeneralFragment cannot be cast to android.support.v4.app.Fragment

Here is my code in Fragment,

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentTabHost;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;



public class FAQFragment extends Fragment{
FragmentTabHost mTabHost = null;

public View onCreateView(LayoutInflater inflater, ViewGroup    container,
                         Bundle savedInstanceState) {
    mTabHost = new FragmentTabHost(getActivity());

    mTabHost.setup(getActivity(), getChildFragmentManager(),
            android.R.id.tabcontent);

    mTabHost.addTab(mTabHost.newTabSpec("sub1").setIndicator("General"),
            FQAGeneralFragment.class, null);

    mTabHost.addTab(mTabHost.newTabSpec("sub2").setIndicator("Endor"),
            FQAEndorFragment.class, null);


    return mTabHost;
    }
}

Could someone help me to see how to solve this. And the library and package are all most recent version.

The Logcat error is pointing to FQAGeneralFragment as the error. I do not know FQAGeneralFragment type. I suspect it is not android.support.v4.app.Fragment class type. I would think FQAGeneralFragment is defined in another Java file, and you need to import android.support.v4.app.Fragment.

Please check it out and have fun...
