I run your sample code and when I read a nfc tag,it gives me a java io exception error sometimes.when it success it return a minus tag id (F.E. -1037655583) which is not same as its real id. What's more ,the tag can only be read once unless I exit the scan page and enter again.
Do you have any idea of how it happened and how to solve this ? Thanks.
