Send Data Via Post Android to PHP

Question

So, i'm trying to send message via Post in Android to PHP here is the Android Java Function:

 //enviando para o backend
private void SendtoPHP(String reg) throws IOException {


    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http://bubbledev.com.br/gcm/getdevice.php");

    try{
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
        nameValuePairs.add(new BasicNameValuePair("regid", "" + reg ));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        HttpResponse response = httpclient.execute(httppost);


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

}

The PHP:

<?php       
include 'conecta.php';
$device_token  = urldecode($_POST['regid']);    
$sql = "INSERT INTO corposa.deviceandroid"
              . " (id,device_token)"
              . " VALUES (NULL,'$device_token')";
mysqli_query($con,$sql);

?>

The PHP is Just fine, I already tested it with a another Post and worked, but when the Android function tries $device_token dont recive any value and the SQL save a "" with the id at the table

I use this code which is similar to yours, except the ResponseHandler. It works for me.

HttpClient Client = new DefaultHttpClient();

List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("id", sID));
nameValuePairs.add(new BasicNameValuePair("etc", sETC));

try {           

    String SetServerString = "";

    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http://your-url.com/script.php");
    httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
    ResponseHandler<String> responseHandler = new BasicResponseHandler();

    SetServerString = httpclient.execute(httppost, responseHandler);                

}  catch(Exception ex) {
    // failed
}

NameValuePair is now considered as deprecated by Android studio - here is a separate thread on SO: stackoverflow.com/questions/29220755/namevaluepair-deprecated

I'm sure there are better ways to do this, but this is how I usually handle post requests from Android:

<?php
{
    $input = json_encode(file_get_contents("php://input"));

    $deviceToken = $input->regId;
    mysqli_query($connection, "INSERT INTO corposa.deviceandroid (`id`, `device_token`) VALUES(NULL, '" . mysqli_real_escape_string($deviceToken) . "')";
}

Also, since you're using POST instead of GET, the data being passed to the server isn't url encoded, so urldecode isn't needed here.

Code seems ok, only "strange" thing is:

List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);

because you are adding only ONE BasicNameValuePair to the list. Maybe that is the problem...?

I use this code in my current project, hope it's works for you too

  Map<String, String> kvPairs = new HashMap<String, String>();
    kvPairs.put("regid", reg);
    HttpClient httpclient = this.getNewHttpClient();
    HttpPost httppost = new HttpPost("http://bubbledev.com.br/gcm/getdevice.php");
    if (kvPairs != null && kvPairs.isEmpty() == false) {
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(kvPairs.size());
        String k, v;
        Iterator<String> itKeys = kvPairs.keySet().iterator();
        while (itKeys.hasNext()) {
            k = itKeys.next();
            v = kvPairs.get(k);
            nameValuePairs.add(new BasicNameValuePair(k, v));
        }
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs, "UTF-8"));
    }
    HttpResponse response;
    response = httpclient.execute(httppost);
    String responseString = EntityUtils.toString(response.getEntity());

Also need this method in your class

public static HttpClient getNewHttpClient() {
    try {
        KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
        trustStore.load(null, null);

        SSLSocketFactory sf = new RecorridoSSL(trustStore);
        sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

        HttpParams params = new BasicHttpParams();
        HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
        HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);

        SchemeRegistry registry = new SchemeRegistry();
        registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
        registry.register(new Scheme("https", sf, 443));

        ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);

        return new DefaultHttpClient(ccm, params);
    } catch (Exception e) {
        return new DefaultHttpClient();
    }
}

hope I don't forgot anything, other way tell me

Guys the error was in my PHP

$device_token  = urldecode($_POST['regid']);

This urldecode was messing out with my code haha

Thx for all help
