Thank you, mobile development. /s

Tried to create a default Navigation Drawer activity on Android Studio, result:

- Compilation erros out of nowhere
- R. couldn't compile even after cleaning and rebuilding the project
- Couldn't reverse the damage because I didn't save it before doing it (who would imagine a custom activity would do this)
- Lost 2 hours of work

I'm just not that desperate because I have the project on Github, but I'll have to make all the changes over again and it will take sometime before remembering everything.
