Hello everyone!
Does anyone know of any resources for Android UI design?
Why does the UI design require a higher resolution than iOS?
The PNG files will export from Photoshop at 72dpi.

This is the standard resolutions for the Android devices (in px):
LDPI: 240 x 360,
MDPI: 320 x 480,
TVDPI: 426 x 639,
HDPI: 480 x 720,
XHDPI: 640 x 960,
XXHDPI: 960 x 1440,
XXXHDPI: 1280 x 1920,

I get the screen resolution part. What I don't understand is why the high dpi resolution.

Full Stack JavaScript Techdegree Student 5,130 PointsI get that but the PNG files are exported from Photoshop at 72dpi.
I'm just trying to understand if the PNG files are suppose to be exported from Photoshop at a higher dpi resolution and how?
Thanks for your feedback BTW!
