Quality of master branch

[hannesa2]

Just for your info, I did a short test of your master branch. I run immediate into

    java.lang.RuntimeException: Unable to start activity ComponentInfo{app.familygem/app.familygem.ProfileActivity}: java.lang.NullPointerException: Attempt to invoke virtual method 'void androidx.appcompat.app.ActionBar.setDisplayHomeAsUpEnabled(boolean)' on a null object reference

Doing this big refactoring without a CI, which at least starts each activity is a no go. It introduces too much errors.
I at least started to make Espresso tests during pull requests to avoid this.

To be honest, that's why I can't base my fork on this repo

Interesting to see Kotlin works without these changes

If you do so, you'll run into tons of errors

Btw, .gitignore is broken now
