Android Question Why with BETA 13.00 #2 (64 bit ) I have bigger *apk

Hi everyone,

I have a strange situation.
Now when I compile the application (with BETA 13.00) it is bigger than usual (12.80).

If I unpack the final *.apk I have folders:
commonMain
kotlin
nonJvmMain
and more files... (it can be seen on the screenshot)



Question:
What could be the cause because there is no Kotlin in the code?
