How to prepare graphics for a mobile game?

Question

Android

We decided to make a game for android and naturally stumbled upon screen resolutions. Turning the forums, we found out that the preparation of graphics should be packaged for different screens.
The dpi issue remains a mystery to me. In Photoshop, how to expose it correctly?
I'm assuming dpi is 72. Correct me if it's wrong.

Answer 1

Photoshop - at the beginning of the pipeline. At the end of the farm, you will still have something like community.imgtec.com/developers/powervr/tools/pvrt... (well, not necessarily exactly that, whatever), packing textures into atlases, supporting the desired texture compression on the platform etc. Cut there.

Answer 2

In the design for the screen, dpi does not affect the display of the picture in any way. This option only affects the print detail of the picture on physical media.
