Hello team ,
We are encountering the following exception frequently when using #AndroidSDK with #DESFire EV3 8k card
com.nxp.nfclib.exceptions.InvalidResponseLengthException: Incomplete response
at com.nxp.nfclib.desfire.DESFireEV1.readRecords(:2827)
at com.nxp.nfclib.desfire.DESFireEV2.readRecords(:2026)
We would appreciate your assistance with the following:
What are the possible causes or scenarios that could trigger this InvalidResponseLengthException?
How can we properly handle this exception in our application without requiring the card to be formatted?
Thank you for your support.

Generally, the standard process for accessing an EV3 card is as follows: Get and Select the existing application ID(AID) and file ID (FID), then authenticate. After successful authentication, you can read and write the data in the file.
