 value1=url1+"userid="+pg.getuserid()+"&amp;chapterid="+pg.getchapterid()+"&amp;pageno="+pg.getpageno()+"&amp;view%20time="+pg.getviewtime()+"&amp;IMEI%20no="+pg.getimeino()+"&amp;feedback="+pg.getfeedback()+"&amp;Comments="+pg.getcomments();
//Toast.makeText(getApplicationContext(), value1, Toast.LENGTH_LONG).show();
 System.out.println(value1);
// feedbackdata feedback1=new feedbackdata();
 feedbak.execute(value1);
    feedbackdata.loadingProgress = GUIStaticMethod.returnProgressBar(getApplicationContext());

        //myLoginDataFatcher.start();

GUIStaticMethod.mProgressDialog.setOnDismissListener(new OnDismissListener() {

    public void onDismiss(DialogInterface dialog) {



        if(res1.contains("Page View Insertion Successfully")==true)
        {
            Toast.makeText(getApplicationContext(), res1, Toast.LENGTH_LONG).show();

        }
