How do I create a circle via a drawable from Java (not Xml)?

Issue

I want to create a drawable that contains a circle with a background color that comes from an external file. As such I unfortunately can't simply load the drawable from an Xml file but have to create it dynamically in Java. How do I create my circle directly in Java?

Solution

I finally found a nonhacky way to create an oval shaped drawable:

    GradientDrawable gd = new GradientDrawable();
    int fillColor = Color.parseColor("FF0000");
    gd.setColor(fillColor);
    int strokeWidth = 2; // px not dp
    int strokeColor = Color.parseColor("#000000");
    gd.setStroke(strokeWidth, strokeColor);
    gd.setShape(GradientDrawable.OVAL);
