Sending HTTP Post Request with Android

by

You can use Http Client from Apache Commons. For example:

private class PostTask extends AsyncTask<String, String, String> {
  @Override
  protected String doInBackground(String... data) {
    // Create a new HttpClient and Post Header
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http://<ip address>:3000");

    try {
      //add data
      List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
      nameValuePairs.add(new BasicNameValuePair("data", data[0]));
      httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
      //execute http post
      HttpResponse response = httpclient.execute(httppost);

    } catch (ClientProtocolException e) {

    } catch (IOException e) {

    }
  }
}

UPDATE

You can use Volley Android Networking Library to post your data. Official document is here.

I personally use Android Asynchronous Http Client for few REST Client projects.

Other tool that good to explore is Retrofit.
