Inflater working on emulator, but not on real device

Question

I'm fairly new to android app development, I'm doing it now for my project on faculty in Android Studio (using API 23). I'll go straight to the point: Application that I'm developing works (is not showing any fatal errors) on emulator when I run it, but as soon as I run it on actual device, it crashes with error "Binary XML file line #12: Error inflating class fragment".

Full stack trace:
