           //doFileUpload();
           try {
            // setiap parameter yang akan dikirim melalui http
            // harus encode agar
            // dapat terbaca dengan baik oleh server
            Cursor c = helper.getAll1(almagId);
            Cursor cr = helper.getUpImage(almagId);
                if(c.moveToFirst()){
                    //progressD = ProgressDialog.show(context, title, message)
                        do{
                            String kdstore = URLEncoder.encode(helper.getKdStore(c).toString(), "utf-8");
                            String nama = URLEncoder.encode(helper.getNama(c).toString(), "utf-8");
                            String alamat = URLEncoder.encode(helper.getAlamat(c).toString(), "utf-8");
                            String kdpos = URLEncoder.encode(helper.getKdPos(c).toString(), "utf-8");
                            String notelp = URLEncoder.encode(helper.getNotel(c).toString(), "utf-8");
                            String lng = URLEncoder.encode(helper.getlng(c).toString(), "utf-8");
                            String lat = URLEncoder.encode(helper.getLat(c).toString(), "utf-8");
                            String perush = URLEncoder.encode(helper.getPerus(c).toString(), "utf-8");
                            //String gambar = URLEncoder.encode(helper.getGamb(c).toString(), "utf-8");

                            //Toast.makeText(this, kdstore, Toast.LENGTH_LONG).show();
                            //System.out.println(gambar);
                            url += "?kode_toko=" + kdstore + "&&nama=" + nama + "&&alamat=" + alamat + 
                            "&&kode_pos=" + kdpos + "&&no_telp=" + notelp + "&&longitude=" + lng + "&&latitude=" + lat +
                            "&&perusahaan=" + perush;
                            getRequest(url);
                            url = "http://10.234.165.232/upload_get.php";
                        }while(c.moveToNext());
            }
            if(cr.moveToFirst()){
                do{
                    String kdstore = URLEncoder.encode(helper.getKdstore1(cr), "utf-8");
                    String gambar = URLEncoder.encode(helper.getGam1(cr), "utf-8");
                    url1 += "?kode_toko1=" + kdstore + "&&gambar1=" + gambar;
                    getRequest1(url1);
                    url1 = "http://10.234.165.232/upload_get2.php";
                }while(cr.moveToNext());
            }

            } catch (UnsupportedEncodingException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
           MenuUtama.this.runOnUiThread(new Runnable(){
               public void run() {
                   if(progressD.isShowing())
                       progressD.dismiss();
               }
           });
       }
});
thread.start();
return(true);

and error like this :

FATAL EXCEPTION: Thread-9
java.lang.RuntimeException: 
Can't create handler inside thread that has not called Looper.prepare()
    at android.os.Handler.<init>(Handler.java:121)

    at com.sat.alfaloc.MenuUtama$1.run(MenuUtama.java:101)
    at java.lang.Thread.run(Thread.java:1096)

if activity save data in to server I command the progress bar can run,but if not this not worked..what should i do to fix this problem??

Answer 1

Probably you are getting error because of the thread in which you are using the context of the activity.

You should use the AsyncTask instead of a normal thread.
In AsyncTask there is a method onPreExecute() and onPostExecute() which are executing on the main thread and there is a method doInBackground() which will execute on background so that you can easily implement the long live process.

You can refer this example
