how to resolve java.net.ConnectException: failed to connect to /10.0.2.2 (port 8080): connect failed: ETIMEDOUT (Connection timed out)




I m making an application which should upload file from sd card to php server for further processing but when i try to upload my logcat shows the following error: java.net.ConnectException: failed to connect to /10.0.2.2 (port 8080): connect failed: ETIMEDOUT (Connection timed out). My java code is as below.

package de.smsbackup;

import android.R;
import android.app.Activity;
import android.os.Bundle;
import android.os.Environment;

    try {
        // ------------------ CLIENT REQUEST

        Log.e(Tag, "Inside second Method");

        FileInputStream fileInputStream = new FileInputStream(new File(
                exsistingFileName));

        dos.writeBytes(twoHyphens + boundary + lineEnd);
        dos.writeBytes("Content-Disposition: post-data; name=uploadedfile;filename="
                        + exsistingFileName + "" + lineEnd);

        // close streams

        dos.close();

    } catch (MalformedURLException ex) {

    }

    catch (IOException ioe) {
        Log.e(Tag, "error: " + ioe.getMessage(), ioe);
    }


    try {
        BufferedReader rd = new BufferedReader(new InputStreamReader(conn
                .getInputStream()));
        String line;
        while ((line = rd.readLine()) != null) {
            Log.e("Dialoge Box", "Message: " + line);
        }
        rd.close();

    } catch (IOException ioex) {
        Log.e("Note Pad", "error: " + ioex.getMessage(), ioex);
    }
}
}

My PHP file is as below:




<?php
// Where the file is going to be placed 
 $ target_path = "admin/";

 /* Add the original filename to our target path.  
  Result is "uploads/filename.extension" */
 $ target_path = $ target_path . basename( $ _FILES['uploadedfile']['name']); 

 if(move_uploaded_file($ _FILES['uploadedfile']['tmp_name'], $ target_path)) {
  echo "The file ".  basename( $ _FILES['uploadedfile']['name']). 
  " has been uploaded";
  chmod ("uploads/".basename( $ _FILES['uploadedfile']['name']), 0644);
} else{
 echo "There was an error uploading the file, please try again!";
 echo "filename: " .  basename( $ _FILES['uploadedfile']['name']);
 echo "target_path: " .$ target_path;
}
?>

Please could any one tell me ASAP that where i m wrong? Thanks.
