Android How to get tab with icon and text in Android version 3.0 plus - android-tabhost

Question

I am working on Android Tabs with sdk minimum version API 11 and target is API 17. I have written code like this.
public class MainScreenActivity extends TabActivity{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_screen);
TabHost tabHost = getTabHost();
Intent homeIntent = new Intent(this, HomeScreenView.class);
tabHost.addTab(tabHost.newTabSpec("Home")
.setIndicator("Home", getResources().getDrawable(R.drawable.home_states))
.setContent(homeIntent));
}
}
and I am using standard Tab xml file like this.
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<RelativeLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true" />
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
</RelativeLayout>
</TabHost>
I am not getting icon for tab and also tab text is showing in capital letter. If I set the sdkminVersion 8 and remove the target then its works fine. please help me out.
