Background colour of tabs

I am trying to add colours to tabs of action bar with the help of following link-https://github.com/thecodepath/android_guides/wiki/ActionBar-Tabs-with-Fragments

I added following statements to style.xml-

<style name="MyTheme" parent="@android:style/Theme.Holo.Light">
        <item name="android:actionBarStyle">@style/MyActionBar</item>
        <item name="android:actionBarTabStyle">@style/MyTheme.ActionBar.TabView</item>

    </style>
  <style name="MyActionBar" parent="@android:style/Widget.Holo.Light.ActionBar">
        <item name="android:windowFullscreen">true</item>
        <item name="android:windowContentOverlay">@null</item>
        <item name="android:background">#12ABEE</item>
        <item name="android:actionMenuTextColor">#ffffff</item>
        <item name="android:titleTextStyle">@style/myTheme.ActionBar.Text</item>
    </style>

    <style name="myTheme.ActionBar.Text" parent="@android:style/TextAppearance">
        <item name="android:textColor">#ffffff</item>
        <item name="android:textStyle">bold</item>
        <item name="android:gravity">center</item>
    </style>
 <style name="MyTheme.ActionBar.TabView" parent="android:style/Widget.Holo.ActionBar.TabView">
        <item name="android:background">@drawable/tab_bar_background</item>
    </style>

Also i created tab_bar_background.xml in drawable-

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- UNSELECTED TAB STATE -->
    <item android:state_selected="false" android:state_pressed="false">
        <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
            <!-- Bottom indicator color for the UNSELECTED tab state -->
            <item android:top="-5dp" android:left="-5dp" android:right="-5dp">
                <shape android:shape="rectangle">
                    <stroke android:color="#65acee" android:width="2dp"/>
                </shape>
            </item>
        </layer-list>
    </item>
    <!-- SELECTED TAB STATE -->
    <item android:state_selected="true" android:state_pressed="false">
        <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
            <!-- Tab background color for the SELECTED tab state -->
            <item>
                <shape>
                    <solid android:color="#cef9ff"/>
                </shape>
            </item>
            <!-- Bottom indicator color for the SELECTED tab state -->
            <item android:top="-5dp" android:left="-5dp" android:right="-5dp">
                <shape android:shape="rectangle">
                    <stroke android:color="#5beea6" android:width="2dp"/>
                </shape>
            </item>
        </layer-list>
    </item>
</selector>

With these steps in place it should show tab with light blue backgroung(#cef9ff) and green bottom line(#5beea6) on selected and blue bottom line and normal background on unselected.But unfortunately while running i see that bottom line appears fine but the background colour of tab appears black both for selected and unselected tabs.I am not able to figure out wht went wrong..

Updating tab_bar_background.xml to this solved my problem 

<?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android">
        <!-- UNSELECTED TAB STATE -->
        <item android:state_selected="false" android:state_pressed="false">
            <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
                <!-- Bottom indicator color for the UNSELECTED tab state -->
                <item >
                    <shape >
                        <stroke android:color="#e8e8e8"  android:width="25dp" />
                    </shape>
                </item>
            </layer-list>
        </item>
        <!-- SELECTED TAB STATE -->
        <item android:state_selected="true" android:state_pressed="false">
            <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
                <!-- Tab background color for the SELECTED tab state -->

                <!-- Bottom indicator color for the SELECTED tab state -->
                <item>
                    <shape >
                        <stroke android:color="#ffd866"   android:width="25dp"/>
                    </shape>
                </item>
            </layer-list>
        </item>
    </selector>
