How to properly use resources from assets?

Question

Android

Would it be correct to place images from the maximum size in assets, and when accessing them, form images using the device dimensions, save them in the cache and use them from there on subsequent launches?

Answer 1

Not really, as it is often redundant.
If assets, then these are not resources!

Answer 2

It is possible to store several sizes of each image in drawable. The right one will be automatically selected depending on the size of the display.
It 's well described in the documentation .
