There is a hard-coded string here, does this need to be defined somewhere so it can be changed easily? 

The yes/no dialogue is a separate class here, where similar ones are generally just functions in the file of the activity where they are used. Would it be better to have all similar questions as classes, or have this one integrated into the EditActivity file? @dschuermann can advise please? Also, I tested this functionality too, it works nicely :)
