Is there a way to get Roboto Medium (font-weight: 500) to work in Android?

The font-weight: 500 style works fine for iOS, but not for Android. Do I need to use a different font-family? I tried some of the values here (http://stackoverflow.com/a/13329907/650516 – like font-family: “sans-serif-medium” ) with no luck.
