    barcode.setX(1f);       
    barcode.setY(75f);

    barcode.setLeftMargin(10f);
    barcode.setRightMargin(10f);
    barcode.setTopMargin(10f);
    barcode.setBottomMargin(10f);

    barcode.setShowText(true);

    barcode.setTextFont(new AndroidFont("Arial", Typeface.NORMAL, 12));     
    barcode.setTextMargin(6);
    barcode.setTextColor(AndroidColor.black);       

    barcode.setBackColor(AndroidColor.white);     
    RectF bounds = new RectF(30, 30, 0, 0);
    try {
       barcode.drawBarcode(canvas, bounds);
       l1.draw(canvas);
       l1.addView(t1); 
    } catch (Exception e) {
       // TODO Auto-generated catch block
       e.printStackTrace();
    }

If you want to generate bar code for desired information, then use this code

package com.barcodegeneration.in;

import com.onbarcode.barcode.android.AndroidColor;
import com.onbarcode.barcode.android.AndroidFont;
import com.onbarcode.barcode.android.Code128;
import com.onbarcode.barcode.android.Code39;
import com.onbarcode.barcode.android.IBarcode;

import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.Canvas;
import android.graphics.RectF;
import android.graphics.Typeface;
import android.view.View;

public class MakeBarcode extends View{

    public MakeBarcode(Context context) {

        super(context);
        System.out.println("im in view class");
        // TODO Auto-generated constructor stub
    }
public void onDraw(Canvas canvas)
{
    super.onDraw(canvas);
     try {
        generate_barcode(canvas);
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}
public static void generate_barcode(Canvas canvas)throws Exception {
    Code128 barcode = new Code128();
    barcode.setData("ash");
  //  barcode.setData("ashutosh");
    barcode.setProcessTilde(false);
    System.out.println("i m inside code 39 without static mmm");
    System.out.println("i m inside code 39 mmm");
    barcode.setUom(IBarcode.UOM_PIXEL);

    barcode.setX(1f);

    barcode.setY(75f);

    barcode.setLeftMargin(10f);
    barcode.setRightMargin(10f);
    barcode.setTopMargin(10f);
    barcode.setBottomMargin(10f);


    barcode.setResolution(72);


    barcode.setShowText(true);

    barcode.setTextFont(new AndroidFont("Arial", Typeface.NORMAL, 12));

    barcode.setTextMargin(6);
    barcode.setTextColor(AndroidColor.black);


    barcode.setBackColor(AndroidColor.white);

        RectF bounds = new RectF(30, 30, 0, 0);
        try {

    barcode.drawBarcode(canvas, bounds);


        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }       
}

}
