I started Android programming from the command line using make/ant and testing on a device because I didn't like Android Studio. This ended up wasting a lot of time and energy over the years as I had to integrate more 3rd party libraries (including Google's own crap).
Same thing for iOS. I didn't like building GUIs in Interface Builder so I did everything in code. Over time as iOS devices came in different sizes, this became harder to do properly. I should have given in early and learned to use Interface Builder, auto layout, etc.
