Android Studio throws this error when I use byte[]

ERROR: expected parameters: byte[] actual parameters: byte[][]

and this error when I pass byte: "type argument cant be of primitive type"

class PrintOrderTaskSTARIO extends AsyncTask<byte[], Void, Void> {

     ......

@Override
protected Void doInBackground(byte[]... print) {

    String portName = "";
    String portSettings = "9100";

    StarIOPort port = null;
    System.out.println("2");

    //TRY TO PRINT....
    try
    {
        port = StarIOPort.getPort("tcp:10.1.10.18", "9100", 10000);

        //Start checking the completion of printing
        port.writePort(print, 0, print.length);

What does `byte...` mean? What does `byte[]...` mean? – Sotirios Delimanolis Sep 17 '14 at 19:18

Because you're using `byte[]` as varargs. – Luiggi Mendoza Sep 17 '14 at 19:18
