Customizable Android colors via JavaScript

[reichhartd]

At the moment, you can not customize the colors for Android via JavaScript.
For Android it is a bit more complicated than for iOS, because for Android the customizations are controlled via the colors.xml.
One way to solve this could be to override the getResources method of the MainActivity to exchange the respective color-keys. Unfortunately, I don't have that much experience with Android development to judge if this is so easily possible and best practice.

Help for this issue is gratefully accepted.
