Mobile and tablet screen sizes?

Question

Android

Hello.
I don’t quite understand about screens ..
If I put a layout in ps, 1080x1920, does that mean it is in xxhdpi ?

mobile

0.75 ldpi = 240x320
1 mdpi = 360х640 (320х480)
1.5 hdpi = 540х960 (480х640)
2 xhdpi = 720х1280 (640х960)
3 xxhdpi = 1080х1920
--------------------------------------------------------------------------------------
tablet

0.75 ldpi = 540x960
1 mdpi = 720x1280 (768х1280)
1.5 hdpi = 540х960 (480х640)
2 xhdpi = 1080х1920
3 xxhdpi = 1440x2560 (1536x2048)

It's right?
And I don’t really understand how on tablets xxhdpi 1440x2560, more precisely where to shove the icon in xxhdpi for tablets?
I will be very grateful

The pixel density on the screen is determined not only by the resolution, but also by the screen size.
For example, if the 1080x1920 layout is designed for a 5" Nexus 5 screen, then yes, it's xxhdpi. And if you were counting on a huge tablet, then the pixel density will be lower.
