Is hdpi and mdpi still used in android kitkat and up Have a general question if this is something that could be ruled out or it all depends.

I am developing an app for Android KitKat and above. But i have never seen a phone that have hdpi and are able to upgrade the OS to KitKat.

Is there a way to see how many phones still uses hdpi and mdpi? 
Because it will be a big problem for me if i need to support every screen.
I always keep this page bookmarked for things like this.

You can make some educated guesses using this data.

As of Feb 1 2016, the percentage of devices on an OS version pre-KitKat (if I did the math correctly) is 29.2%.

Since 42.4% of all devices have hdpi screen density... 

At least 13.2% of all devices out there are hdpi with KitKat or later.

It's likely that it's more, since you can count on most of the ldpi/mdpi devices being in the pre-KitKat group.

If all 16.2% of ldpi/mdpi devices are in the pre-KitKat group (which most likely are), then the total hdpi KitKat-and-later group grows to 29.5%
