RFID Manager error

I have a TC200J and RFD2000 device. From the zebra portal at: https://www.zebra.com/us/en/support-downloads/software/utilities/RFID-Manager-Application-for-RFD2000.html I downloaded the apk and installed it on the TC200J device . The RFID Manager program does not work. Connecting the device to Android Studio in Debug I see the following errors:

I tried to install the Zebra_RFID_Mobile_API-2.2.7.0.apk program, but the RFD2000 reader is not recognized.

could you give me support.

Thank you
