Help Ripping Revolt 3 apk

Hello there.

I recently downloaded the apk of Revolt 3 (yes, there is a new Revolt game - even though it bears little similarity to its original counterpart) with the intent of ripping the cars and textures, but I have little clue on how to open .dat files within it.

Would anyone be kind enough to point me out a neat tutorial where I can find the answers I'm looking for to decompile and extract these files?
