Cant authenticate my ACS token

Ive been trying to send messages to a azure service bus queue from android for a while and i just cant get it to work. This is the code i use for getting the ACS SWT:
private void getTokenFromACS() throws ClientProtocolException, IOException {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("https://servicebusnamespace-sb.accesscontrol.windows.net/WRAPv0.9/");
List<NameValuePair> parameters = new ArrayList<NameValuePair>(3);
parameters.add(new BasicNameValuePair("wrap_name", "name"));
parameters.add(new BasicNameValuePair("wrap_password", "password associated with the name"));
parameters.add(new BasicNameValuePair("wrap_scope", "Realm url"));
httppost.setEntity(new UrlEncodedFormEntity(parameters));
BasicHttpResponse httpResponse = null;
httpResponse = (BasicHttpResponse)httpclient.execute(httppost);
BufferedReader reader = new BufferedReader(new InputStreamReader(httpResponse.getEntity().getContent(), "UTF-8"));
String[] tokenVariables = URLDecoder.decode(reader.readLine()).split("&wrap_access_token_expires_in=");
authorizationToken = tokenVariables[0];
}
This works fine, i get a string that has the wrap_access_token, issuer, audience, expiresOn and HMACSHA256.
What i try to do after that is to send a message with this token like this:
HttpClient requestClient = new DefaultHttpClient();
HttpPost post = new HttpPost("https://servicebusnamespace.servicebus.windows.net/queuename/messages");
post.addHeader("Authorization", "WRAP access_token=\""+authorizationToken+"\"");
Item item = new Item();
Date date = new Date();
item.setDate(date);
item.setId(1);
item.setRoadName("roadname");
item.setSpeed(60.0);
item.setLat(12.12);
item.setLng(12.12);
String json = new GsonBuilder().create().toJson(item, Item.class);
post.setEntity(new ByteArrayEntity(json.getBytes("UTF8")));
HttpResponse httpResponse = requestClient.execute(post);
This always result in my Token not being authenticated, i get the error message saying my token doesnt containt a signature or that it doesnt have the audience set. What could be wrong?
Note that this is on android =)
Thanks in advance!

Seems like you are missing some code. Your authorizationToken is currently something like this: "wrap_access_token=net.windows.servicebus.action%3dLis..."
The only thing you want is the part after the equal-sign.
I think this will do:
String[] tokenVariables = URLDecoder.decode(reader.readLine()).split("&wrap_access_token_expires_in=")[0].split("=");
authorizationToken = tokenVariables[1];

Alternative for UrlEncodedFormEntity for sending data via POST

When sending the POST request using UrlEncodedFormEntity which takes List as input parameter along with the key, my request gets converted in the form of [key={json}] .
But the request i want to send should be in the form of key={json} , i.e not as List.
So, is there any alternative for the given method when using POST?
notes: webservice is working fine , and since it is json ,i cannot use Soap .
i ve tested it using POSTman and webservices are WCF(if thats of any use..)
if any code is required , please mention it.
Thanks in advance.
Edit code:
HttpClient client = new DefaultHttpClient();
HttpPost request = new HttpPost(URL);
List<NameValuePair> value=new ArrayList<NameValuePair>();
value.add(new BasicNameValuePair("data",string));
//here it passes as List and here is where i want an alternate method
// by which i can send parameter as JSONobject
UrlEncodedFormEntity entity=new UrlEncodedFormEntity(value);
request.setEntity(entity);
HttpResponse response = client.execute(request);
HttpEntity entity2 = response.getEntity();
if(entity2.getContentLength() != 0) {
Reader tapReader = new InputStreamReader(response.getEntity().getContent());
char[] buffer = new char[(int) response.getEntity().getContentLength()];
tapReader.read(buffer);
tapReader.close();
JSONObject tapJsonObj = new JSONObject(buffer);

Android POST JSON OBJECT - How to set $_POST Index

i have a JSONObject which i want to POST to a server.
Here is the Code:
JSONObject obj = new JSONObject();
for(int k = 0; k<len;k++){
obj.put("nachrichten_ids", params[k]);
}
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost("xxxxx");
HttpEntity entity;
StringEntity s = new StringEntity(obj.toString());
s.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
entity = s;
httpPost.setEntity(entity);
HttpResponse response;
response = httpClient.execute(httpPost);
By doing Log.i("TEST",obj) i get the JSON object:
{"nachrichten_ids":"[2144,2138]"}
That data is send to the server. But i cant access it:
There is no $_POST index. (PHP)
How to set a index, so that i can access the json object, like $_POST['nachrichten_ids'].
I had to work with that data then e.g with php json_decode()
Any idea ?
Thanks

Try putting your jSON object into a namevaluepair. The name of the pair you add is the name you should use when reading it on the web. For example here I will get Password by calling $_POST['Password'].
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("Password", "My password"));
nameValuePairs.add(new BasicNameValuePair("Mail", "My mail"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute HTTP Post Request
BasicHttpResponse response = (BasicHttpResponse) httpclient.execute(httppost);
HttpEntity entity = response.getEntity();

posting the data using httpput in android

I have a problem in posting the data to server by using httpput methods in android.I have to send feedback to server and getting json response. but i am getting 404 bad request. but i dont know where is the problem.
I am strucked here and didn't find any solution. Any suggestions?
My code is as follows:
HttpClient client = new DefaultHttpClient();
HttpPut put = new HttpPut(getString(R.string.feedBack));
List<NameValuePair> pairs = new ArrayList<NameValuePair>();
pairs.add(new BasicNameValuePair("userId", "8"));
pairs.add(new BasicNameValuePair("feedback",feedbackMessage
.getText().toString()));
put.addHeader("Content-Type", "application/json");
put.addHeader("Accept", "application/json");
put.setEntity(new UrlEncodedFormEntity(pairs));
HttpResponse response = client.execute(put);
Log.d(tag, "Result" + response.getStatusLine());

You are not initializing a URL object and passing in simple String.
You should do this instead:
URL url = new URL(getString(R.string.feedBack));
HttpClient client = new DefaultHttpClient();
HttpPut put= new HttpPut(url);
And it should work.

What is wrong with this POST request with json on android?

I'm trying to perform a POST request to a server that wants the Content-Type set to application/json with name and email as some keys. Currently, I'm getting a 406 error, which I'm assuming is working on the server side, but android can't handle the response. How can I tweak the code to get a 200 response?
HttpClient client = new DefaultHttpClient();
HttpEntity entity;
try{
JSONObject j = new JSONObject();
j.put("name" , myName);
j.put("email", myEmail);
HttpPost post = new HttpPost(targetURL);
post.setHeader("Content-Type", "application/json");
StringEntity se = new StringEntity(j.toString(), HTTP.UTF_8);
se.setContentType("application/json");
post.setEntity(se);
HttpResponse response = client.execute(post);
entity = response.getEntity();
Log.d("response", response.getStatusLine().toString());
} catch(Exception e){Log.e("exception", e.toString());}
Does that look about right? Do I need one of those response handlers when creating the HttpClient?

This works for me with json-2.0.jar
HttpClient client = new DefaultHttpClient();
HttpConnectionParams.setConnectionTimeout(client.getParams(), MyApplication.HTTP_TIMEOUT); //Timeout Limit
HttpResponse response;
ArrayList<appResults> arrayList = new ArrayList<appResults>();
String resul;
try{
HttpGet get = new HttpGet(urls[0]);
response = client.execute(get);
/*Checking response */
if(response!=null){
InputStream in = response.getEntity().getContent(); //Get the data in the entity
resul = convertStreamToString(in);
Gson gson = new Gson();
Type listType = new TypeToken<ArrayList<appResults>>() {}.getType();
arrayList = gson.fromJson(resul, listType);
in.close();
of course in asynctask or thread.
But 406... it seems that your format on your webserver and your app are not consistent...
