Android Question How to send byte array to Smart Card

After reading your posts I realized that I cannot call a class as static if it is public. The problem I have now is how to forward the byte array to the methods, I read the posts but I didn't find anything similar.

I just write in B4A what i see in library and that wotk :)

B4X: 
    Dim ADPU_SEND(520) As Byte
    Dim bytePos As Int = 0
        
    For i = 0 To 3
        ADPU_SEND(i) = cmd(i)
    Next
    Dim LoByte As Byte = Lc / 256
    Dim HiByte As Byte = Lc  Mod 256
    
    ADPU_SEND(4) = LoByte
    ADPU_SEND(5) = HiByte
    
    bytePos = 6
    For i = 0 To Data.Length-1
        ADPU_SEND(bytePos) = Data(i)
        bytePos = bytePos + 1
    Next
    Dim bLen As Int = Le + 4
    Dim LoByte As Byte = bLen / 256
    Dim HiByte As Byte = bLen  Mod 256

    ADPU_SEND(518) = LoByte
    ADPU_SEND(519) = HiByte

Thanks for helping

hi again
What is here problem with this error?

B4X: 
    Dim recvBuffer(520) As Byte
    Log("slot "& slotNum)
    mReader.RunMethod ("transmit",Array  (slotNum, cmd, cmd.Length, recvBuffer, recvBuffer.Length))
    Log(bytesToHexString(recvBuffer))

i have no idea what is on line 68...
my guess would be this line
mReader.RunMethod ("transmit",Array (slotNum, cmd, cmd.Length, recvBuffer, recvBuffer.Length))
Click to expand...
has caused the error.
i do not know what the cmd is, i do not know if you are connected. you refuse to use try/catch blocks. you are not listening. it's very difficult for me.

Ciontek CS10 is POS android printer wich have build in Printer and Smard card reader. I have and other types of POS without Smart card reader. My intention is to write driver for smart card reader and use over USB C adapter. How that looks like you can see on picture.

the topic of this theme is "How to send byte array to Smart Card"
i was hoping to help, but we are very far from that now.

you don't answer questions, you post lines of meaningless codes:
B4X: 
state=0

i have no idea what any of that means. and i have no access to any of the software you are using.
i have to stop. i'm sorry. i wish you good luck.
