Android background image size for XXHDPI

问题

I need to set the background picture for my app, the only problem is that i dont know what size the image has to be for XXHDPI devices.

I read here for MDPI, HDPI and XHDPI devices, but nothing for XXHDPI: Android splash screen image sizes to fit all devices

So, what size does the background has to be for drawable-xxhdpi folder?

回答1:

MDPI is your baseline. Means the base size.

LDPI is 0.75*MPDI

HDPI is 1.5*MDPI

XHDPI is 2*MPDI

XXHDPI is 3*MDPI

XXXHDPI is 4*MDPI
