Android style is not working in API 13 and lower versions

I'm working on android sample project handling styles in all the versions of android. Style is working in Android API 14(ICS) and above but it is not working in API 13 and lower versions.

My Layout file is

<?xml version="1.0" encoding="utf-8"?>

<FrameLayout xmlns:android="http://ift.tt/nIICcg"
    xmlns:tools="http://ift.tt/LrGmb4"
    android:layout_width="fill_parent"

    android:layout_marginTop="5dp">

    <LinearLayout

In API level 13 and below the style is not applying/working. Can anyone let me know where i'm going wrong.

This is user authentication UI.
