Check this code

JSONArray json = //your array;
HttpClient httpClient = new DefaultHttpClient();
HttpContext httpContext = new BasicHttpContext();
HttpPost httpPost = new HttpPost("http://your_url");

try {

    StringEntity se = new StringEntity(json.toString());

    httpPost.setEntity(se);
    httpPost.setHeader("Accept", "application/json");
    httpPost.setHeader("Content-type", "application/json");


    HttpResponse response = httpClient.execute(httpPost, httpContext); //execute your request and parse response
    HttpEntity entity = response.getEntity();

    String jsonString = EntityUtils.toString(entity); //if response in JSON format

} catch (Exception e) {
    e.printStackTrace();
}

Android doesn't have special code for sending and receiving HTTP, you can use standard Java code. I'd recommend using the Apache HTTP client, which comes with Android. Here's a snippet of code I used to send an HTTP POST.

try {   int TIMEOUT_MILLISEC = 10000;  // = 10 seconds
        HttpParams httpParams = new BasicHttpParams();
        HttpConnectionParams.setConnectionTimeout(httpParams, TIMEOUT_MILLISEC);
        HttpConnectionParams.setSoTimeout(httpParams, TIMEOUT_MILLISEC);
        HttpClient client =new DefaultHttpClient(httpParams);   
        HttpPost request =new HttpPost("");
        request.setEntity(new ByteArrayEntity(postMessage.toString().getBytes("UTF8")));
        HttpResponse response = client.execute(request);
        }catch (Exception e) {        
        }
