POSTing JSON/XML using android-async-http (loopj)

I am using android-async-http and really liking it. I've run into a problem with POSTing data. I have to post data to the API in the following format: -

<request>
  <notes>Test api support</notes>
  <hours>3</hours>
  <project_id type="integer">3</project_id>
  <task_id type="integer">14</task_id>
  <spent_at type="date">Tue, 17 Oct 2006</spent_at>
</request>

As per the documentation, I tried doing it using RequestParams, but it is failing. Is this any other way to do it? I can POST equivalent JSON too. Any ideas?

Solution 1:

Loopj POST examples - extended from their Twitter example:

private static AsyncHttpClient client = new AsyncHttpClient();

To post normally via RequestParams:

RequestParams params = new RequestParams();
params.put("notes", "Test api support"); 
client.post(restApiUrl, params, responseHandler);

To post JSON:

JSONObject jsonParams = new JSONObject();
jsonParams.put("notes", "Test api support");
StringEntity entity = new StringEntity(jsonParams.toString());
client.post(context, restApiUrl, entity, "application/json",
    responseHandler);

Solution 2:

@Timothy answer did not work for me.

I defined the Content-Type of the StringEntity to make it work:

JSONObject jsonParams = new JSONObject();
jsonParams.put("notes", "Test api support");

StringEntity entity = new StringEntity(jsonParams.toString());
entity.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));

client.post(context, restApiUrl, entity, "application/json", responseHandler);

Good Luck :)
