i trying display image through bitmap fetching mysql image not getting displayed. i've tried lot couldn't thing. here php code:

<?php $mysqli = new mysqli('localhost', 'root', '', 'demo'); if (mysqli_connect_error()) {     die('connect error (' . mysqli_connect_errno() . ') '             . mysqli_connect_error()); }     if($_server['request_method']=='get'){         $id = $_get['id'];         $sql = "select * output_images imageid='$id'";         $r = mysqli_query($mysqli,$sql);         $result = mysqli_fetch_array($r);         header('content-type: image/jpeg');         echo base64_decode($result['imagedata']);         mysqli_close($mysqli);       }else{         echo "error";     } ?> 

here android code fetches imagedata table , displays through bitmap.

public class testmainactivity extends activity implements onclicklistener {     edittext enterid;     button fetchimage;     imageview img;     @override     protected void oncreate(bundle savedinstancestate) {         strictmode.enabledefaults();         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_test_main);         enterid = (edittext)findviewbyid(r.id.edittext1);         fetchimage = (button) findviewbyid(r.id.button1);         img = (imageview)findviewbyid(r.id.imageview1);         fetchimage.setonclicklistener(this);     }     private void getimage() {         // todo auto-generated method stub         class getimage extends asynctask<string,void,bitmap>         {             protected void onpreexecute(){                           }             protected bitmap doinbackground(string...params){                 string id = params[0];                 string url1 = "http://12.0.0.1/demo_d/getimage.php?imageid="+id;                 bitmap image = null;                 try{                     url url = new url(url1);                     image = bitmapfactory.decodestream(url.openconnection().getinputstream());                 }                 catch(exception e){                     toast.maketext(getapplicationcontext(), (charsequence) e, toast.length_long).show();                 }                 return image;             }             protected void onpostexecute(bitmap image){                 super.onpostexecute(image);                 img.setimagebitmap(image);             }    }     string id1 = enterid.gettext().tostring();     getimage =new getimage();     i.execute(id1); }     @override     public void onclick(view arg0) {         // todo auto-generated method stub         getimage();     } } 

after execution of code found no errors there imageview blank , required image not been displayed.

looks trying use machine while running code on android emulator because using ip 127.0.0.1.

if use 127.0.0.1 on emulator points itself.

to access host machine emulator should use http://10.0.2.2:8080.

so, url should this

string url1 = "http://10.0.2.2:8080/demo_d/getimage.php?imageid="+id; 

see this more information on matter.
