Ask DN: How do you prepare assets for Android?

almost 5 years ago from , UI Designer at Rocker Creative

I'm currently working on some Android app designs. The client asks me to prepare assets for icons and other graphics. As we all know, Android has tons of screen resolutions. Some of them use different sizes for assets (ldpi, mdpi, hdpi, xhdpi, xxhdpi, xxxhdpi). I'm wondering how you manage all this stuff. So for example you create app design in Sketch (because it's super easy in Sketch to export different sizes of assets). As a foundation, I use screen resolution = 720x1280px (I think it's one of the Nexus resolutions). From this point, what multiplier should I use for each asset size?

Or maybe do you have some other technique for doing this?
