There is no way you can hide the res folder in final apk. Even if you manage to do it by some encryption, it will be highly discourage since it will have severe performance impact.

res folder shouldn't have any sensitive data which needs such protection. If your intention is to have some sensitive data, then put it in assets folder and use tools like dexguard to encrypt it.
