Android - Can't create simple rectangle shape… UnsupportedOperationException?

Question

I\'m having trouble creating a simple rounded rectangle using XML. Every time I try to add the \"corners\" element to the custom shape I get:

So, I was just playing around with this a bit and I changed a couple of lines in the rounded_rectangle.xml to get it working. See below:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle"> 
    <solid android:color="#ffffff"/>    

    <stroke android:width="3dp"
            android:color="#ff000000"/>

    <padding android:left="1dp"
             android:top="1dp"
             android:right="1dp"
             android:bottom="1dp"/> 

    <corners android:radius="30dp"/> 
</shape>

I only wish Google would put out a proper reference doc for creating XML-based shapes. After hours (4+) of hunting down examples on the Web, I feel like it's still a guessing game as to what elements/attributes are supported in these types of XML documents. Sorry for the mini-rant.

I hope this helps someone else.
