Idle Handler threw exception

Hi,

We are developing app on android platform with Unity. And while switching the scene, we got the following errors which cause app freezed. Does any suffering similar issue?

Make sure that before switching the scene you unsubscribed from all NuitrackManager events (in your code), for example,
NuitrackManager.onHandsTrackerUpdate += some_method;
NuitrackManager.onUserTrackerUpdate += some_method;
and etc.This can be done in the OnDestroy method of the same script, where the subscription for the target event was performed.
Unity calls OnDestroy () before destroying the object, to which this script is attached.For example,
void OnDestroy()
{
NuitrackManager.onHandsTrackerUpdate -= some_method;
NuitrackManager.onUserTrackerUpdate -= some_method;
}
