APK size is abnormaly big

I have this strange issue.
I’m building game for android and getting APK of 107 MB size. How it is possible?

In Windows Explorer my projects Assets folder is 75MB. I’m building only for ARMv7.
I’m using latest Unity 2017.3.0f3 (Personal)
Also I couldn’t find that *Player size statistics* shown here in my Editor log. I only found this uncompresed data statistics, which doesn’t even add up to 100%:

Any help?

I don’t know. Try looking at this: Unity - Manual: Reducing the file size of your build
