Android xxx-hdpi real devices
android, android-icons, dpi, icons
Solution
You shouldn't really need `xxxhdpi`. It was only introduced because of the way that launcher icons are scaled on the nexus 5's launcher
Edit Back when I answered in Jan 2014, the Nexus 5 was the only device using `xxxhdpi`. Now many devices including the Nexus 6 and LG G3 use it. So it would be a good idea to include it in your app.
Problem
I'm gonna release my app, it's a 1.2Mb apk that includes about 120 icons in 4 different formats (ldpi, mdpi, hdpi, x-hdpi). If I add xx-dpi and xxx-hdpi icons the apk grows bigger and loading time increases. There are many entry-level devices out there with really loooow memory and I'd like my app to run everywhere. Do I really need to add xx-hdpi? And is there a real device that requires xxx-hdpi?
