How to Execute HTTP POST Requests in Android (with Pictures)

HTTP POST requests are essential to any Android application that utilizes the Internet. Here's how to implement the functionality.
STEPS

1

DECLARE INTERNET PERMISSIONS IN THE MANIFEST BY ADDING THE FOLLOWING LINE TO ANDROIDMANIFEST.XML. This allows your application to use any Internet connections.

2

CREATE YOUR HTTPCLIENT AND HTTPPOST OBJECTS TO EXECUTE THE POST REQUEST. The address object is a String representing your POST's destination, such as a PHP page.
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(address);

3

SET YOUR POST DATA. This is done by creating and setting a list of NameValuePairs as your HttpPost's entity. Be sure to catch the UnsupportedEncodingException thrown by HttpPost.setEntity().
List pairs = new ArrayList();
pairs.add(new BasicNameValuePair("key1", "value1"));
pairs.add(new BasicNameValuePair("key2", "value2"));
post.setEntity(new UrlEncodedFormEntity(pairs));

4

EXECUTE THE POST REQUEST. This returns an HttpResponse object, whose data can be extracted and parsed. Be sure to catch the ClientProtocolException and IOException thrown.
HttpResponse response = client.execute(post);
