Когда я устанавливаю minifyenabled = true, я получаю NullPointerException в какой-то части моего приложения.
Вот ошибка.
java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.TextView.setText(java.lang.CharSequence)' on a null object reference
at application.screens.g.b.a$d$1.a(SourceFile:97)
at application.a.p$b.onClick(SourceFile:31)
at android.view.View.performClick(View.java:6605)
Цель состоит в том, чтобы открыть фрагмент списка городов при нажатии текстовое представление из фрагмента и отображать его в текстовом представлении, когда оттуда выбирается город. Когда я выбираю город из citylistfragment, textviewe выдает ошибку при установке данных. Но ошибка возникает только при открытии прогарда.
