I am trying to create a native ad like this:
nativeExpressAdView = new NativeExpressAdView(adUnitId, new AdSize(360, 150), AdPosition.Bottom); 
Instead of hardcoding the screen width as 360, I would like to use the full-width available on the device. Smart banners work great for banner ads, but passing AdSize.SmartBanner as second argument does not work here.
Screen.width returns actual pixels. 
Is there a way to obtain the width in dp that I can pass onto the AdSize constructor?
