How to add FragmentTabHost dynamically with icon set for each Tab, when my Activity class extends ActionBarActivity

Question

I checked one of the solution which asks to use .setIndicator(View view) and add your Tab title and icon in your layout file. But I want to add dynamically FragmentTabHost along with setting its icons. So can anyone answer how to use .setIndicator(View view) with an example of adding say 3 tabs dynamically?

public class MainActivity extends ActionBarActivity {

    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(), android.R.id.tabcontent);

        Drawable icon = getResources().getDrawable(R.drawable.icon);
        mTabHost.addTab(mTabHost.newTabSpec("tab1").setIndicator("Tab 1", icon), FragmentTab.class, null);
    }
}
