Same issue here, any schedule or work around?

Crash happened in :

if (VERSION.SDK_INT >= 14) {
           this.mSelectorPosition = (Integer)ReflectionUtils.getFieldValue(AbsListView.class, "mSelectorPosition", this);
       } else {
           this.mSelectorPosition = (Integer)ReflectionUtils.getFieldValue(AbsListView.class, "mMotionPosition", this);
       }

in dispatchDraw(Canvas), where ReflectionUtils.getFieldValue(AbsListView.class, "mSelectorPosition", this) returns null. So problem is that will author upgrade this library anymore?

用ExpandableListView 替换掉FloatingGroupExpandableListView即可解决奔溃问题。引发的原因是：mSelectorPosition在android10（sdk= 30）上被添加了注解 @UnsupportedAppUsage(maxTargetSdk = Build.VERSION_CODES.P 最大sdk =28 ) int mSelectorPosition = INVALID_POSITION;ReflectionUtils.getFieldValue(AbsListView.class, "mSelectorPosition", this)使用反射是拿不到这个成员变量的值的。

Hello, Will there be an update for Android 10 ?

意思是不用推荐用这个库吗?直接用ExpandableListView ?

reflection sucks, reflection not public field sucks.
