How can I connect android to a php web service

Question

can anybody guide me to a tutorial or a working example of connecting android to a php web service using ksoap2 or something else?

Answer 1

Im using my PHP-Webservice this way:

Java:

// params => "?action=getInfos"
private JSONObject getJSONObject(String params)
{
    try
    {
        String url = path2webservicephp + params;

        System.out.println("Call URL: " + url);

        HttpGet request = new HttpGet(url);

        request.setHeader("Content-Type", "text/xml;charset=UTF-8");

        DefaultHttpClient httpclient2 = new DefaultHttpClient();

        HttpResponse response = httpclient2.execute(request);

        if (response.getStatusLine().getStatusCode() != 200)
            throw new ConnectionException("Status Code is " + response.getStatusLine().getStatusCode() + ": " + response.getStatusLine().getReasonPhrase());

        BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
        String line = reader.readLine();

        MyConstants.RECEIVEDBYTES += line.length();

        reader.close();
        if ("[]".equals(line))
            return null;
        return new JSONObject(line);
    }
    catch (Exception e)
    {
        LLog.e(Webservice.class, "Exception! params: " + params);
        LLog.e(e, Webservice.class);
    }
    return null;
}

// LLog.e is from my own class. It logs to Log.e and into a file

PHP:

$array = array('status' => 'ok', 'message' => 'your action was: '.$_GET['action']);
echo json_encode($array);
