Today I will describe shortly how to execute http GET and POST request on Android platform.
The code is very simple and straightforward, for post request with attachement, you would have to add apache-mime4j-0.6.jar and httpmime-4.0.1.jar to your build path.

HTTP GET

try {
        HttpClient client = new DefaultHttpClient();  
        String getURL = "http://www.google.com";
        HttpGet get = new HttpGet(getURL);
        HttpResponse responseGet = client.execute(get);  
        HttpEntity resEntityGet = responseGet.getEntity();  
        if (resEntityGet != null) {  
                    //do something with the response
                    Log.i("GET RESPONSE",EntityUtils.toString(resEntityGet));
                }
} catch (Exception e) {
    e.printStackTrace();
}

HTTP POST

     try {
        HttpClient client = new DefaultHttpClient();  
        String postURL = "http://somepostaddress.com";
        HttpPost post = new HttpPost(postURL);
            List<NameValuePair> params = new ArrayList<NameValuePair>();
            params.add(new BasicNameValuePair("user", "kris"));
            params.add(new BasicNameValuePair("pass", "xyz"));
            UrlEncodedFormEntity ent = new UrlEncodedFormEntity(params,HTTP.UTF_8);
            post.setEntity(ent);
            HttpResponse responsePOST = client.execute(post);  
            HttpEntity resEntity = responsePOST.getEntity();  
            if (resEntity != null) {    
                Log.i("RESPONSE",EntityUtils.toString(resEntity));
            }
    } catch (Exception e) {
        e.printStackTrace();
    }

HTTP POST with File attachment

File file = new File("path/to/your/file.txt");
try {
         HttpClient client = new DefaultHttpClient();  
         String postURL = "http://someposturl.com";
         HttpPost post = new HttpPost(postURL);
     FileBody bin = new FileBody(file);
     MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);  
     reqEntity.addPart("myFile", bin);
     post.setEntity(reqEntity);  
     HttpResponse response = client.execute(post);  
     HttpEntity resEntity = response.getEntity();  
     if (resEntity != null) {    
               Log.i("RESPONSE",EntityUtils.toString(resEntity));
         }
} catch (Exception e) {
    e.printStackTrace();
}

Hope this helps!
