Android Tabhost within Tabhost Not Working (XML issue I think)

Question

I have done this before, but for the life of me I cant remember. I'm wanting a tab with in a tab. This is my mainactivity

protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        TabHost tabHost = getTabHost();

        TabHost.TabSpec Login = tabHost.newTabSpec("Login");
        // setting Title and Icon for the Tab
        Login.setIndicator("", getApplicationContext().getResources().getDrawable(R.drawable.tab1));
        Intent LoginIntent = new Intent(this, Tab1Activity.class);
        LoginIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        Login.setContent(LoginIntent);


        // Tab for jobs
        TabHost.TabSpec Jobs = tabHost.newTabSpec("Jobs");
        Jobs.setIndicator("", getApplicationContext().getResources().getDrawable(R.drawable.tab2));
        Intent JobsIntent = new Intent(this, Tab2Activity.class);
        JobsIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        Jobs.setContent(JobsIntent);


        TabHost.TabSpec Jobs3 = tabHost.newTabSpec("Jobs3");
        Jobs3.setIndicator("", getApplicationContext().getResources().getDrawable(R.drawable.tab3));
        Intent JobsIntent3 = new Intent(this, Tab3Activity.class);
        JobsIntent3.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        Jobs3.setContent(JobsIntent3);



        // Adding all TabSpec to TabHost
        tabHost.addTab(Login);
        tabHost.addTab(Jobs);
        tabHost.addTab(Jobs3);
    }

This is Tab2Activity.java

public class Tab2Activity extends TabActivity
{



    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.tab2);

        /////////////////////////

        TabHost tabHost2 = getTabHost();

        TabHost.TabSpec Gmapped = tabHost2.newTabSpec("InnerTabs");

        // setting Title and Icon for the Tab
        Gmapped.setIndicator("", getApplicationContext().getResources().getDrawable(R.drawable.tab3));
        Intent GmappedIntent = new Intent(this, Tab3Activity.class);
        GmappedIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        Gmapped.setContent(GmappedIntent);

        tabHost2.addTab(Gmapped);
}

and Tab2.xml

If you want an advice, use TabLayout instead, is more easy:
