Element shape doesn't have required attribute android:layout_height

I'm using a shape element to put as the background of a view, doing as this SO question. I'm using Android Studio and it tells me that...

Element shape doesn't have required attribute android:layout_height

Element shape doesn't have required attribute android:layout_width

The code is as follows:

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

<solid android:color="@color/darkBrown"/>
<stroke android:layout_width="match_parent" android:layout_height="match_parent"/>
<corners android:radius="10dip"/>
<padding android:left="0dip" android:right="0dip" android:top="0dip" android:bottom="0dip"/>

</shape>

So basically my question: why do I get this error if shapes technically don't need these attributes? How can I tell android to stop marking it as an error or how can I avoid it?

Thank you.

SOLVED: The reason was because it wasn't inside the drawable folder.

EDIT: Yes I'm aware the stroke part is incorrect.

You drawable XML is not correct in the first place. You cannot just use attributes you like and expect it work, for example your has android:layout_width and android:layout_height which makes no sense for and is not supported. It also android:width though, but this is different width and got NOTHING in common with layout_width. Docs are here and include all attributes supported.

The reason the error was shown is because it wasn't inside the drawable folder. (It moved automatically to layout when I renamed the drawable folder after a typo.)

Here is an example of what a shape should look like: 

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<corners
    android:radius="14dp"
    />
<solid
    android:color="#ADD8E6"
    />
<padding
    android:left="0dp"
    android:top="0dp"
    android:right="0dp"
    android:bottom="0dp"
    />
<size
    android:width="100dp"
    android:height="60dp"
    />
<stroke
    android:width="3dp"
    android:color="#ADD8E6"
    />

</shape>
