Android Studio app crashes on launch when using ?colorVariant in xml drawable

I have a shape in one of my xml drawables that uses the styles of my themes.xml file:

<shape android:shape="oval">
    <gradient
        android:gradientRadius="134dp"
        android:startColor="?colorPrimary"
        android:centerColor="#000000"
        android:endColor="#000111"
        android:type="radial" />
</shape>

As you can see startColor uses the colorPrimary attribute. However, when I launch the app in the Android Studio emulator it crashes without build error. When I replace ?colorPrimary by a random hex color everything seems to be fine. I'm using API 24 and as far as I know you can use ?colorVariant for >API 21. Not sure what I'm doing wrong here.

use something like this android:startColor="@color/purple_500" see your colors.xml and call your colors from there

OR

If you want to use 2 colors for day and night go into your project directory resources folder(res) and create new folder name drawable-night and copy your shape.xml from drawable and paste it in drawable-night go to android studio now you have 2 shape.xml files one is night and the other one is for day add colors like you want to add like for
shape.xml add android:startColor="@color/purple_500"
and for shape.xml(night) add android:startColor="@color/purple_200"
