It is very important for a mobile application too talk to web based applications. There are various scenarios where we need to fetch data from web pages .

The code below will enable your android app to talk to a webpage.

Note : You also need to enable uses permission for internet in the android.manifest file.

<uses-permission
        android:name="android.permission.INTERNET" />
Code for android app


public void postData(String toPost) {
// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.URL.com/yourpage.php");

//This is the data to send
String MyName = 'adil'; //any data to send

try {
// Add your data
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
nameValuePairs.add(new BasicNameValuePair("action", MyName));

httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

// Execute HTTP Post Request

ResponseHandler<String> responseHandler = new BasicResponseHandler();
String response = httpclient.execute(httppost, responseHandler);

//This is the response from a php application
String reverseString = response;
Toast.makeText(this, "response" + reverseString, Toast.LENGTH_LONG).show();

} catch (ClientProtocolException e) {
Toast.makeText(this, "CPE response " + e.toString(), Toast.LENGTH_LONG).show();
// TODO Auto-generated catch block
} catch (IOException e) {
Toast.makeText(this, "IOE response " + e.toString(), Toast.LENGTH_LONG).show();
// TODO Auto-generated catch block
}

}//end postData()

php code

<?php

//code to reverse the string

$reversed = strrev($_POST["action"]);

echo $reversed;

?>
