First you cannot pass parameter like this in http post, use below code for your use, there might be some compilation error as am not using and IDE for checking code which am posting, main point is to show you how to pass post parameters using http post, which is by using NameValuePairs, please adjust your url accordingly

        try {
           HttpPost httppost = new HttpPost("https://www.googleapis.com/plus/v1/people/me");
           List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
           nameValuePairs.add(new BasicNameValuePair("key", "12345"));
           httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

            HttpResponse httpResponse = httpClient.execute(httpPost);
            HttpEntity httpEntity = httpResponse.getEntity();
            InputStream is = httpEntity.getContent();
            BufferedReader reader = new BufferedReader(new InputStreamReader(
                    is, "iso-8859-1"), 8);
            StringBuilder sb = new StringBuilder();
            String line = null;
            while ((line = reader.readLine()) != null) {
                sb.append(line + "\n");
            }
            is.close();
            String json = sb.toString();
            Log.i("JSON", json);

        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

There is a Difference between POST and GET method...

In GET METHOD you can pass data with URL....
but in POST method you can not pass data with URL... you have to pass it as entity......... Do the following for Passing Data To the URL

Try This..

      DefaultHttpClient httpClient = new DefaultHttpClient(new BasicHttpParams());
        HttpPost httpPost = new HttpPost(WEBSITE_URL);
        try{    
            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();

            //use this to pass variables while using POST method
            // add an HTTP variable and value pair
            nameValuePairs.add(new BasicNameValuePair("key name","key value")); 
            nameValuePairs.add(new BasicNameValuePair("key name","key value"));
            nameValuePairs.add(new BasicNameValuePair("key name","key value"));

            // passing data to the URL
            httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

            //do the following..

           }

For your solution You should pass

nameValuePairs.add(new BasicNameValuePair("key",token));

Where,

 Key - variable or key you defined in Your page (Backend side)     
 token = is a value which you want to pass..........

This is the posting for authentication. This will return a HttpResponse containing the access token in which you will use when you do a HttpGet request.

  try {
        Log.i(tag, "Starting doHTTPPost");
        List<NameValuePair> pairs = new ArrayList<NameValuePair>();
        pairs.add(new BasicNameValuePair("KEY", "VALUE"));

        /* EXAMPLE of pairs */
        pairs.add(new BasicNameValuePair("client_id","theGreatSecret12345"));
        pairs.add(new BasicNameValuePair("username", "purple"));
        pairs.add(new BasicNameValuePair("password", "asjdf098732hkndfa"));

        HttpClient client = new DefaultHttpClient();
        HttpPost post = new HttpPost("The API Server you want to access");
        post.setEntity(new UrlEncodedFormEntity(pairs));
        HttpResponse response = client.execute(post);
        HttpResponse apiResponse = response;
        String resultFromServerAsAString = EntityUtils.toString(response.getEntity());

        Log.i(tag, "Response statusCode : "+response.getStatusLine().getStatusCode());
        Log.i(tag, "Response StatusLine : "+response.getStatusLine());
        Log.i(tag, "Ending doHTTPPost");

    } catch (UnsupportedEncodingException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
