Error on executing HTTP request in android

问题

I know it may seems to dumb question and there are lots of such questions but I have problems but I can't figure it out what does errors in log means. I know these http methods are deprecated and I should replace them, but I want to get response now. This is my code:

    try
    {
        response = httpClient.execute(httpRequest);
        responseCode = response.getStatusLine().getStatusCode();
        responsePhrase = response.getStatusLine().getReasonPhrase();
        HttpEntity responseEntity = response.getEntity();
        if(responseEntity != null)
        {
            InputStream is = responseEntity.getContent();
            responseString = convertStreamToString(is);
            try
            {
                is.close();
            } catch (Exception ignored) { }
        }
        else
            return "";
    }
    catch (IOException e)
    {
        onError(e);
    }

The codes goes to catch block when it tries to run httpClient.execute and the e object is null. This is log:

        at dalvik.system.NativeStart.main(Native Method)

I couldn't figure it out what errors are. I searched through web I couldn't find anything about saveIpMessageDraft or mIpMessageDraft. What is wrong with my code?
