TelephonyManager.iccTransmitApduBasicChannel data argument format

Question

I am using Telephony Manager to transmit APDU commands to the SIM. I have the MODIFY_PHONE_STATE permission.

I am using the below function:

String iccTransmitApduBasicChannel (int cla, int instruction, int p1, int p2, int p3, String data)

I want to know the format of the argument data. Is it in int or hex or other format?

The data parameter of the method iccTransmitApduBasicChannel() corresponds to the DATA field of the APDU. Each byte of that field is represented as 2-digit hexadecimal value.
