Question

I’m getting exceptions when I’m trying to POST and my JSON has some international characters.

This is code that I use:

HttpPost request = new HttpPost(serviceURL + url);
            request.addHeader("Authorization", "Basic " + Preferences.getAuthorizationTicket(mContext));
            request.addHeader("DeviceSerialNumber", Utility.getDeviceSerialNumber(mContext));
            request.addHeader("OSVersion", "Android v" + Build.VERSION.RELEASE);

            StringEntity entity = new StringEntity(requestData);
            entity.setContentType("application/json;charset=UTF-8");
            entity.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE,"application/json;charset=UTF-8"));
            request.setEntity(entity);

            ResponseHandler<String> handler = new BasicResponseHandler();
            response.Body = mHttpClient.execute(request, handler);
            response.Code = HttpURLConnection.HTTP_OK;
            response.Message = "OK";

And this is error I’m getting:

org.apache.http.client.HttpResponseException:

When requestData doesn’t have any international (russian, polish, etc) letters than it works fine. What do I miss? Or better yet how do I get traffic from emulator captured in Fiddler or something?

I believe you should specify UTF-8 charset when you create StringEntity:

StringEntity entity = new StringEntity(requestData,"utf-8");
