@override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);      fetch= (button) findviewbyid(r.id.fetch);     text = (textview) findviewbyid(r.id.text);     et = (edittext) findviewbyid(r.id.et);      fetch.setonclicklistener(this); }  class task extends asynctask<string, string, void> { private progressdialog progressdialog = new         progressdialog(mainactivity.this);     inputstream = null ;     string result = "";     protected void onpreexecute() {        progressdialog.setmessage("fetching data...");        progressdialog.show();        progressdialog.setoncancellistener(new oncancellistener() {     @override         public void oncancel(dialoginterface arg0) {         task.this.cancel(true);        }     });      }        @override     protected void doinbackground(string... params) {       string url_select = "http://www.andyapp.byethost4.com/demo.php";        httpclient httpclient = new defaulthttpclient();       httppost httppost = new httppost(url_select);            arraylist<namevaluepair> param = new arraylist<namevaluepair>();          try {         httppost.setentity(new urlencodedformentity(param));          httpresponse httpresponse = httpclient.execute(httppost);         httpentity httpentity = httpresponse.getentity();          //read content         =  httpentity.getcontent();                            } catch (exception e) {          log.e("log_tag", "error in http connection "+e.tostring());         //toast.maketext(mainactivity.this, "please try again", toast.length_long).show();         }     try {         bufferedreader br = new bufferedreader(new inputstreamreader(is));         stringbuilder sb = new stringbuilder();         string line = "";         while((line=br.readline())!=null)         {            sb.append(line+"\n");         }             is.close();             result=sb.tostring();                                 } catch (exception e) {                     // todo: handle exception                     log.e("log_tag", "error converting result "+e.tostring());                 }              return null;          }     protected void onpostexecute(void v) {          // ambil data dari json database         try {             jsonarray jarray = new jsonarray(result);             for(int i=0;i<jarray.length();i++)             {             jsonobject jasonobject = null;             jasonobject = jarray.getjsonobject(i);              //get output on screen              string name = jasonobject.getstring("name");             string db_detail="";              if(et.gettext().tostring().equalsignorecase(name)) {             db_detail = jasonobject.getstring("detail");             text.settext(db_detail);             break;             }               }             this.progressdialog.dismiss();          } catch (exception e) {             // todo: handle exception             log.e("log_tag", "error parsing data "+e.tostring());         }     }     }  @override public void onclick(view v) {     // todo auto-generated method stub     switch(v.getid()) {     case r.id.fetch : new task().execute();break;     }  } 

}

demo.php looks this

<?php mysql_connect("sql306.byethost4.com","user_name","******") or      die(mysql_error()); mysql_select_db("db_name"); $sql=mysql_query("select * demo"); while($row=mysql_fetch_assoc($sql)) $output[]=$row; print(json_encode($output)); mysql_close(); ?> 

so how overcome error.many help.

you should post json response receive server. error message said had received string "403" means "forbidden". not allowed access php script. in onpostexceute following line fails:

jsonarray jarray = new jsonarray(result);
