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

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);
