ImageButton is missing when drawable-v21 is added

Question

To include ripple effect for my ImageButton I created drawable-v21 folder in res and added the following code

ans_go_btn.xml :-

<?xml version="1.0" encoding="utf-8"?>
<selector
    xmlns:android="http://schemas.android.com/apk/res/android">
    <ripple xmlns:android="http://schemas.android.com/apk/res/android"
        android:color="#c20586">
        <item>
            <shape android:shape="oval">
                <solid android:color="#fa09ad"/>
            </shape>
        </item>
    </ripple>
</selector>

and in drawable directory I have the below code.

ans_go_btn.xml :

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" >
        <shape android:shape="oval"  >
            <solid android:color="@color/black"></solid>
        </shape>
    </item>
    <item android:state_focused="true">
        <shape android:shape="oval"  >
            <solid android:color="@color/light_blue"></solid>
        </shape>
    </item>
    <item >
        <shape android:shape="oval"  >
            <solid android:color="@color/blue_app"></solid>
        </shape>
    </item>
</selector>

Image button has android:background="@drawable/ans_go_btn" attribute.

In kitkat device the ImageButton appears but, not in my Lollipop device. I might be doing some clear mistakes, but I'm not being able to find it out. Please help!

Thanks

First of all, the ans_go_btn in drawable-v21 should be:

<?xml version="1.0" encoding="utf-8"?>
<selector
xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <ripple
            android:color="#c20586">
            <item>
                <shape android:shape="oval">
                    <solid android:color="#fa09ad"/>
                </shape>
            </item>
        </ripple>
    </item>
</selector>

Selector should have item, other than ripple.

Then, you can change the attribute of the item.
