I have tried to create a new drawable 'circle_button.xml'
<?xml version="1.0" encoding="utf-8"?>

<shape xmlns:android="http://schemas.android.com/apk/res/android" 
    android:shape="ring"
    android:innerRadius="0px">  <!-- Dimension Value only NOT an Integer -->
    <!-- Use android:startColor for centre value, moving to android:endColor as the outer. -->
    <gradient 
        android:type="radial"/>
</shape>
This is located 'res/drawable/circle_button.xml'. I am then trying to create and instance of one in my 'activity_main.xml'.
How ever I receive these errors:
Error

activity_fullscreen.xml: Failed to parse file .../res/drawable/circle_button.xml
