How to put a <vector> in a <shape> in Android?

Question

I'm trying to make customizable icons in Android. I made the vector element, but now I want to give it a rounded background, so I tried to place it within a rounded shape. Like this:

<?xml version="1.0" encoding="utf-8"?> <!-- drawable/circle_card_icon.xml --> <shape xmlns:android="http://schemas.android.com/apk/res/android"     android:shape="oval">     <vector xmlns:android="http://schemas.android.com/apk/res/android"         android:height="24dp"         android:width="24dp"         android:viewportWidth="24"         android:viewportHeight="24">         <path android:fillColor="#000"             android:pathData="M20,2H4A2,2 0 0,0 2,4V22L6,18H20A2,2 0 0,0 22,16V4A2,2 0 0,0 20,2M6,9H18V11H6M14,14H6V12H14M18,8H6V6H18" />     </vector> </shape> 

Yet this doesn't work, and I'm trying to achieve the following:

By using only the vector I don't get the background.
(I used this website to generate the vector)

Rather than putting a vector into a shape, I'd use a LayerList Drawable

Something like so:

<?xml version="1.0" encoding="utf-8"?> <layer-list xmlns:android="http://schemas.android.com/apk/res/android">     <item>         <!-- drawable/circle_card_icon.xml -->         <shape xmlns:android="http://schemas.android.com/apk/res/android"             android:shape="oval">             <solid android:color="#8df"/>             <size                  android:width="48dp"                 android:height="48dp"             />         </shape>     </item>     <item android:drawable="@drawable/your_vector_drawable" /> </layer-list>
