Question

Hi i am working on web service application in android.i need a class that handle all exceptions and send receive json data using URL with parameters.please help me any one with good example.

Answer 1

Here’s a snippet from a helper class I wrote to send data via POST.

List<NameValuePair> params = new ArrayList<NameValuePair>();

params.add(new BasicNameValuePair("param1", param1));
params.add(new BasicNameValuePair("param2", param2));

DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost("http://www.blabla.com/posterome");
httpPost.setEntity(new UrlEncodedFormEntity(params));

And to get the response…

HttpResponse httpResponse = httpClient.execute(httpPost);

Classes used in this snippet are in org.apache.http.* package.

As for JSON, JSONObject will suffice.
There are examples on how to use it properly everywhere on the web. Just google it.
