Is there a way to use a similar Framework as materializecss to Design Android Apps? Or apply CSS to my design in an Android App?
In Android you must target to 5.0 and use elements like "toolbar", "palette", between others.
On github you have: https://github.com/wasabeef/awesome-android-ui/blob/master/pages/Material.md with dozens of material design elements, widgets, etc and most of them from Android 2.3+. Those are really easy to use and most of them only need a gradler declaration.
Hope that helps you.
