Get IMEI of a mobile device and send it via POST to a php file

Question

I have found lots of responses about it but all of them are written with deprecated functions or don't work in my case.

I need to get the IMEI number (unic ID of a device) of the mobile device where my app will be installed, and then to send that value (in form of a string) to a php file located in a folder I created in my website (because the app has a webview where I visualize that website and I want to save the IMEI into a data base).

So far, I got this in my code:

public void postData() {
    // Create a new HttpClient and Post Header
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http://www.chapatelo.hol.es/php/postIMEI.php");

    TelephonyManager telephonyManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);

    try {
        // Add your data
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
        nameValuePairs.add(new BasicNameValuePair("IMEI", telephonyManager.getDeviceId()));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        // Execute HTTP Post Request
        HttpResponse response = httpclient.execute(httppost);

    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
    } catch (IOException e) {
        // TODO Auto-generated catch block
    }
}

and I have <uses-permission android:name="android.permission.INTERNET"/> and also <uses-permission android:name="android.permission.READ_PHONE_STATE"/> in the manifest.

And this is the php file:

<?php

require_once("conexion.php");

if(!isset($_SESSION)){
    session_start();
}

$imei = $_POST["IMEI"];

$query1 = "SELECT * FROM usuarios WHERE imei = '$imei'";

if($resp1 = mysqli_query($conexion, $query1)){

    if(mysqli_num_rows($resp1) == 0){

        $query2 = "INSERT INTO usuarios (imei) VALUES ('$imei')";

        if(mysqli_query($conexion, $query2)){
            $_SESSION["imei"] = $imei;
            echo true;
        }else{
            echo "error de conexión";
        }

    }else{
        echo "Ya existe el imei en la db";
    }
}else{
    echo "error de conexión";
}

mysqli_close($conexion);

?>

However, and not mentioning that almost every function such as httpclient is deprecated, nothing of that works.

I gave permitions 755 (read and execute) to the php folder and to the file I access through my app, but nothing happens...

Is there any "new version" of those functions I'm using to get the imei and then send it to the php file?

Is because of the deprecated functions that my app doesn't save the imei in the data base?

                        while ((line = in.readLine()) != null) {
                            sb.append(line + NL);
                        }
                        in.close();
                        String page = sb.toString();
                        System.out.println(page);
                        } finally {
                        if (in != null) {
                            try {

php

<?php
    // to return plain text
    header("Content-Type: plain/text"); 
    $imei = $_GET["imei"];

    $file=fopen("imei.txt","r") or exit("Unable to open file!");

    while(!feof($file))
     {
    if ($imei==chop(fgets($file)))
     echo "True";
     }

    fclose($file);
