Ok, sorry, I made a mistake. There apparently have been some older version of SDK from couple of years ago, which I thought is current one.
The directory in "...\AppData\Local\Android\Sdk" was practically empty with only 1 file inside.
I fully deleted Android Studio and SDK from my system to be certain, and resintalled again using most recent version, and double checked the new paths. Now the building is running (still waiting for result while I type this).
UPDATE: it completed successfully now, and there's app-mygame-release.apk.
Maybe a silly question, but should not it use game's name? or I missed another instruction?
