Just testing TargetSDKVersion 29 with my app and this error is found. TargetSDKVersion 28 is ok and no errors.
java.lang.NoSuchFieldException: No field mFastScroll in class Landroid/widget/AbsListView; (declaration of 'android.widget.AbsListView' appears in /system/framework/framework.jar!classes3.dex)
I did a forum search for mFastScroll and appears to be related to Ultimate ListView library. The functionality of the Ultimate Listview seems to be working as intended with TargetSDKVersion 29.
