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;

?>

Probably more important to explain what problem you are actually trying to solve.

Just to clarify, this is for Android devices connected to your internal network via VPN, and not WiFi?

Are you using a VPN app on the Android device
