file not found exception while uploading file to web server?

I am using following tutorial to upload image file to webserver.

and getting file not found exception here.

try {
         File uploadFile = new File(uriString); 

// file path i receive **content:/media/external/images/media/2**

        FileInputStream fis =   this.openFileInput(uploadFile.getName()); // **ERRoR HERE**

        HttpFileUploader htfu = new HttpFileUploader("http://finditnear.sigmatec.com.pk/inbox/send_remote_reply","noparamshere", uploadFile.getName());
     开发者_如何学Go   htfu.doStart(fis);
        } 
    catch (FileNotFoundException e) {
        Toast.makeText(this, e.toString(), Toast.LENGTH_LONG).show();
        e.printStackTrace();
        return;
        }

image file exists there but still it giving me error.

Can any one guide me what is the solution?

content:/media/external/images/media/2 is incorrect file name, it's a Uri.
So this line

FileInputStream fis =   this.openFileInput(uploadFile.getName());

Should be replaced with

InputStream fis=this.getContentResolver().openInputStream(new Uri(uriString));

Did you add:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

to your AndroidManifest?
