The error occurs when i change activitys (Example), From MainActivity -> goto Schedule page -> return to MainActivity. someone has previously suggested that i need to handle the window token in onPause() and/or onResume() however my attempts todo so have not been sucsessful. without changing activitys, the code runs fine. if anyone can spot what i am missing, that'll be great :)
