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);

@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 :)

a better way to post json

RequestParams params = new RequestParams();    params.put("id", propertyID);    params.put("lt", newPoint.latitude);    params.put("lg", newPoint.longitude);    params.setUseJsonStreamer(true);    ScaanRestClient restClient = new ScaanRestClient(getApplicationContext());    restClient.post("/api-builtin/properties/v1.0/edit/location/", params, new AsyncHttpResponseHandler() {        @Override        public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {        }        @Override        public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {        }    });
