Java Question Problem Creating B4A Library

[Reinaldo]

Hello, i need print to Zebra printer using the Zebra SDK, i do a little app in eclipse and i can print without problems, but when i made the java class to generate B4A library and use into b4a app, the Zebra methods are not operating and it show error.
I put the class code and the error showed in B4a, when i try to use Imprimir() method.

Class code:

package anywheresoftware.b4a.spsoft;

import com.zebra.android.comm.*;




import android.widget.Toast;
import anywheresoftware.b4a.BA;
import anywheresoftware.b4a.BA.Permissions;
import anywheresoftware.b4a.BA.Version;
import anywheresoftware.b4a.BA.ShortName;


@ShortName("Zprint")
@Version(1.0f)
@Permissions(values={"android.permission.BLUETOOTH","android.permission.BLUETOOTH_ADMIN"})
public class Zprint {
    /*
     * Interface for zebra print
     */
    public String macaddress;
    public ZebraPrinterConnection zebraPrinterConnection;
   
   
    public void InitZ (String MACADD){
             
        this.macaddress=MACADD;
        Toast.makeText(BA.applicationContext, this.macaddress, Toast.LENGTH_SHORT).show();
    }
   
    public void Imprimir (BA ba){  
        /*
         * Print CPCL code
         */
       
        String cadena1 = "! 0 200 200 210 1\r\n" + "BARCODE 128 1 1 50 150 10 HORIZ\r\n" + "TEXT 7 0 210 60 HORIZ\r\n" + "VBARCODE 128 1 1 50 10 200 VERT\r\n" + "VTEXT 7 0 60 140 VERT\r\n" + "FORM\r\n" + "PRINT\r\n";
       
        zebraPrinterConnection = new BluetoothPrinterConnection(macaddress);
         byte[] configLabel = null;
         configLabel = cadena1.getBytes();
       
        
        try {
            zebraPrinterConnection.open();
             zebraPrinterConnection.write(configLabel);
            disconnect();
            } catch (Exception e ) {
                disconnect();
            }
        }
   
   
    public void disconnect() {
        try {
           
            if (zebraPrinterConnection != null) {
                zebraPrinterConnection.close();
            }
        } catch (Exception e) {
           
            try {
                zebraPrinterConnection.close();
            } catch (Exception e1) {
                // TODO Auto-generated catch block
                e1.printStackTrace();
            }
           
        }
       
    }
   

}

when try to use Imprimir method, show this:

Is the Zebra SDK in a jar or java files?
If its in a jar you need to add DependsOn annotation.
