I've discovered these colors can be added by creating a small colors.xml file. The values are described in a Stack Overflow answer https://stackoverflow.com/a/52253682/340175

Here's the contents of the file I added to android/src/main/res/values/colors.xml (there seems little hope of a PR being acted on in this repo so more practical to add the info here :).

<resources>
    <color name="ripple_material_dark">#33ffffff</color>
    <color name="ripple_material_light">#1f000000</color>
</resources>

BTW: As the Android code and gradle builds are both ancient here there are other build issues.
