How to decrypt apk files?

Question

Android

Hello. It is necessary to get from the apk of the game - character models. I mean that the game is made using unity, but I do not quite understand how to open these files. I'm not going to use it for commercial purposes, I just need screenshots. Can you tell me how to open the file? Is there a viewer? I've tried changing file extensions to no avail.

Apk files are regular zip. You need to extract some file from Data and set the TrID program on it to determine the file format. If it doesn’t determine anything, then it’s probably somehow cunningly packed or encrypted.
