xamarin.android not main activity，other thread use jscontext，can‘t debug by chrome debug url.
If I use jscontext in main activity,chrome debug url is ok.And In Other Thread,I use jscontext created by main activity,the chrome debug do nothing.If I create jscontext by other thread,not main activity,use debug url ,the app exit with no tips.
