Android HTTP Request for CakePHP URL

Question

I have a website which was created with cakephp. I want to pass some values formed in my App to this website. When I enter the exact same URL in the browser it works.

The URL is something like: www.something.com/function/add/value

So I'm very confused if this is a GET or a POST method? And how I can do that?

The thing is that I can NOT change this URL or put some POST or GET PHP script there to get the values. So I basically just have to call the URL with those params.

This is my code:

HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = null;
try {
        httppost = new HttpPost("www.something.com/function/add/" + URLEncoder.encode(txtMessage.getText().toString(), "UTF-8"));
} catch (UnsupportedEncodingException e1) {
        e1.printStackTrace();
}

try {
        ResponseHandler<String> responseHandler = new BasicResponseHandler();
        httpclient.execute(httppost, responseHandler);
} catch (ClientProtocolException e) {
} catch (IOException e) {
}

Create List<NameValuePair> and put here yours values ("somevalue" in example). Create DefaultHttpClient() set nameValuePairs with yours value.

List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("tag", "TEST_TAG"));
nameValuePairs.add(new BasicNameValuePair("valueKey", "somevalue"));
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("www.something.com/function/add/utils.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs, HTTP.UTF_8));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
InputStream is = entity.getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = "";
while ((line = reader.readLine()) != null) {
    sb.append(line + "n");
}
is.close();
Log.i("response", sb.toString());

On the server side in /function/add/utils.php get yours value

if (isset($_POST['tag']) && $_POST['tag'] != '') {
     $tag = $_POST['tag']; //=TEST_TAG
     $value = $_POST['valueKey']; //=somevalue
}
//and return some info 
$response = array("tag" => $tag, "success" => 0, "error" => 0);
$response["success"] = 1;
echo json_encode($response);

This $response you recive in your java code as HttpEntity entity = response.getEntity(). It may help you.

well I'm sorry I think 8 wasn't clear enough. My url does not include a PHP file or anything. Just a plain URL (The way CakePHP creates them...) The server reads the value from the URL directly. Is there any other way of doing it?

You have a link like www.something.com/function/add/ with some values. Try to find handler-file on the server. In this directory function/add/ must be index.php. Is there?

No there is no PHP file and there is no way that there is ever going to be one. The link www.something.com/function/add/myvaluetobeadded is there that way. CakePHP then knows that "myvaluetobeadded" is the actual value I give to the website, If I navigate to the website with a browser it works great.

ok, i understand. The way with DefaultHttpClient() isnt right. I dont think exactly that this can solve your problem but look how to follow a link. Like a

WebView webView = (WebView) findViewById(R.id.webView); Uri data = Uri.parse("http://www.site.com")); webView.loadUrl(data.toString());

- but this is through opening browser...

Would this also be possible in the background somewhere and without opening the browser?
