I can't use API reflection on androidx.appcompat:appcompat:1.1.0
问题 I have a problem with androidx.appcompat:appcompat:1.1.0. It's a new problem because on androidx.appcompat:appcompat:1.0.2 it does not exist. I have a code that uses reflection to get mPopup Field from the spinner and set its height. It works very well on appcompat:1.0.2 but not on androidx.appcomppat:appcompat:1.1.0. The code is private void setPopUp() { try { Field popup = getPopupField(); // Get private mPopup member variable and try cast to ListPopupWindow final android.widget
