how to implement sdm and mirroring in my android app for NTAG424 DNA

I have tried to implement this but getting error. I want to change key, configure file 2 and start using the tag to mirror the uid, counter and cmac. How exactly to complete this task.

Hello sir,

Thank you for working with our products.

We have an Application note that shows the steps for this implementation: NTAG 424 DNA and NTAG 424 DNA TagTamper features and hints in section 5 Personalization example, the required steps for its implementation are shown.

We highly recommend to please use RFIDDiscover for a proper implementation and, in case you need further support, to have a better understanding of the log.
