Send Data Via Post Android to PHP

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
