NTAGI2C TAG ,Andriod Studio, MIFARE SDK Lite

[michael2015]

Hi;
I am testing a small app that uses the MIFARE SDK Lite with the NTAG12C tag. The tutorial i am following is
UM10809-Getting Started with MIFARE SDK from the mifare. However i am having problem getting
the application to read my Tag, the Nxpnfcliblitecallback () callback method is the issue i believe.

Thanks
