Question

我有一个Android应用程序，它从两个webservices获得响应。用PHP编写的webservices。 Web服务托管在Live服务器中，我的请求将是HTTP和HTTPS.Below代码运行良好 Android 5.0,6.0,7.0，我用4.4.2测试也很好用。但是当我尝试在Android 4.3中运行我的应用程序时，我的应用程序将崩溃。

我尝试过的，

try{

   String url = dRequestParam.getURL();
   HttpEntity httpEntity;
   HttpResponse httpResponse;
   DefaultHttpClient httpClient;

   if(url.startsWith("http://")){
    //http client
    httpClient = new DefaultHttpClient();
    httpEntity = null;
    httpResponse = null;

   }else{

    HostnameVerifier hostnameVerifier = org.apache.http.conn.ssl.SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER;

    DefaultHttpClient client = new DefaultHttpClient();

    SchemeRegistry registry = new SchemeRegistry();
    SSLSocketFactory socketFactory = SSLSocketFactory.getSocketFactory();
    socketFactory.setHostnameVerifier((X509HostnameVerifier) hostnameVerifier);
    registry.register(new Scheme("https", socketFactory, 443));
    SingleClientConnManager mgr = new SingleClientConnManager(client.getParams(), registry);
    httpClient = new DefaultHttpClient(mgr, client.getParams());

    HttpsURLConnection.setDefaultHostnameVerifier(hostnameVerifier);

    int AdFetchTimeout=Integer.parseInt(AdView.getFetchTimeout());
    httpClient.getParams().setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT, AdFetchTimeout);
    httpEntity = null;
    httpResponse = null;
   }
            //checking http request method type
            if(method == POST){
                HttpPost httpPost = new HttpPost();
                //adding post params
                if(params != null){
                    httpPost.setEntity(new UrlEncodedFormEntity(params));
                }
                httpResponse = httpClient.execute(httpPost);
            }else if(method == GET){
                //appending params to url
                params = AdRequestParam.getURL_PARAMS();

                if(params != null){
                    String paramString = URLEncodedUtils.format(params,"utf-8");
                    url += "?" + paramString;
                }

                HttpGet httpGet = new HttpGet(url);

                // SET HEADERS PARAMETERS

                hParams = AdRequestParam.getHEADER_PARAMS();

                for (NameValuePair nvp : hParams) {
                    String name = nvp.getName();
                    String value = nvp.getValue();
                    Cdlog.d(Cdlog.httpReqLogTag,name+"=>"+value);
                    httpGet.setHeader(name,value);
                }
                Long startTime = null;
                try {         
                    startTime = System.currentTimeMillis();
                    httpResponse = httpClient.execute(httpGet);

                    Cdlog.d(Cdlog.httpReqLogTag,url);
                    Cdlog.setLastRequest(url);

                    httpEntity = httpResponse.getEntity();
                    response = EntityUtils.toString(httpEntity);
                    Cdlog.d(Cdlog.httpResLogTag,response);
                    Cdlog.setLastResponse(response);
                  }
                  catch(SocketTimeoutException se) {
                    Long endTime = System.currentTimeMillis();
                    se.printStackTrace();
                  }          
                  catch(ConnectTimeoutException cte) {
                    Long endTime = System.currentTimeMillis();
                  response="{\"ad_available\":\"5\",\"ad_tag\":\"<div></div>\"}";
                    cte.printStackTrace();
                  }
                  catch (ClientProtocolException e) {            
                    e.printStackTrace();
                  }
                  catch (IOException e) {
                    Long endTime = System.currentTimeMillis();

                    e.printStackTrace();
                  }
                //DAC125 Timeout Mechanism

            }


        }catch (UnsupportedEncodingException e){
            Log.d("Unsupported Encoding Exception",e.getMessage());
            e.printStackTrace();
        } catch (ClientProtocolException e){
            Log.d("Client Protocol Exception",e.getMessage());
            e.printStackTrace();
        } catch (IOException e){
            Log.d("IO Exception",e.getMessage());
            e.printStackTrace();
        } catch(SecurityException e){
            Log.d("Security Exception",e.getMessage());
            //response = e.getMessage();
            e.printStackTrace();


        }

        return response;
    }

logcat的：

为什么我的HTTP请求无法在Android OS 4.3及更低版本中运行？
