Android Json to Server sends not data - php

Question

I got a problem. I read a lot here but unfortunately I can't get an answer for my problem.
I want to send a Json post to my Server. The Server should then save the string in my database.
This is my server code so far:
<?php
include('db_connect.php');
$db = new _DB_Connect();
$db->connect();
if(isset($_POST['regid'])){
$data = json_decode($_POST['regid']);
$save_entry = "insert into gcm_users (gcm_regid) values ('$data')";
mysql_query($save_entry) or die (mysql_error());
}else{
echo 'no data get';
}
?>
And this is my method on my android phone.
public String sendJson(View view){
InputStream inputStream = null;
String result = "";
String url2 = "http://192.168.0.5/control_center/functions/incomming.php";
TextView textView_result;
textView_result = (TextView) findViewById(R.id.textView_result);
//strict mode for networking
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
try {
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url2);
httpPost.setHeader("Accept", "application/json");
httpPost.setHeader("Content-Type" , "application/json");
JSONObject jsonObject = new JSONObject();
jsonObject.put("regid", "blablabla");
String json = jsonObject.toString();
StringEntity se = new StringEntity(json);
httpPost.setEntity(se);
HttpResponse httpResponse = httpClient.execute(httpPost);
inputStream = httpResponse.getEntity().getContent();
if(inputStream != null) {
System.out.println(convertInputStreamToString(inputStream));
}
else {
result = "Did not work!";
}
textView_result.setText(httpResponse.toString());
System.out.println(jsonObject.toString());
}catch(JSONException e){
e.printStackTrace();
}catch(UnsupportedEncodingException e){
e.printStackTrace();
}catch(Exception e){
e.printStackTrace();
}
return result;
}
Now the
System.out.println(convertInputStreamToString(inputStream));
tells me that I got no data
echo 'no data get';
So I get a response form the server but I could find my error, why the post data could not be retrieved.
Would appreciate any help or hints. Thank you.

try this...
JSONObject jsonObject = new JSONObject();
jsonObject.put("regid", "blablabla");
String json = jsonObject.toString();
MultipartEntityBuilder multiPart = MultipartEntityBuilder.create();
multiPart.addTextBody("regid",json);
or
multiPart.addTextBody("regid","blablabla");
httpPost.setEntity(multiPart.build());
