Consume WCF Service over SSL in Android

I have been using a WCF (.svc) service for a while for which request format is JSON and response format is XML in an Android application which is working fine. Couple of days ago, I implemented a certificate for SSL purpose on the WCF service from DigiCert (using my wildcard capabilities). The service is accessible from browser and shows no error. Below is the WebConfig

<?xml version="1.0"?>
<configuration>
  <configSections>
    <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
      <section name="IntermediateWebService.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
    </sectionGroup>

          <behavior name="IntermediateWebService.WebBehavior">
              <serviceMetadata httpsGetEnabled="true" />

              <serviceDebug includeExceptionDetailInFaults="true"/>
          </behavior>
        <behavior>

          <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
          <serviceMetadata httpsGetEnabled="true"/>
          <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="false"/>

                  </security>

          </basicHttpBinding>
          <webHttpBinding>

              </binding>
          </webHttpBinding>
      </bindings>
      <services>

          <service behaviorConfiguration="IntermediateWebService.WebBehavior" name="IntermediateWebService.Service1">
              <host>
                  <baseAddresses>
                      <add baseAddress="https://myurl:4445/"/>
                  </baseAddresses>
              </host>
              <endpoint address="" binding="basicHttpBinding" contract="IntermediateWebService.IService1" behaviorConfiguration="WebBehavior" bindingConfiguration="secureHttpBinding" />
          </service>
          <!--<service name="IntermediateWebService.Service1">
               <endpoint address=""
      binding="basicHttpBinding"
      bindingConfiguration="secureHttpBinding"
      contract="IntermediateWebService.IService1"/>



          </service>-->
      </services>
      <serviceHostingEnvironment multipleSiteBindingsEnabled="false" />
  </system.serviceModel>
 <system.webServer>
     <validation validateIntegratedModeConfiguration="false"/>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>
</configuration>

So now while using the same Android code, the response is always

The server cannot service the request because the media type is unsupported.

I have tried using SSL Factory and without it as well.

HttpClient client = getHttpsClient(new DefaultHttpClient()); //new DefaultHttpClient();

            HttpPost get = null;
            commandType = params[0].toString();
            if ("Login".equals(params[0])){

                JSONStringer img = new JSONStringer()
                        .object()
                        .key("value")
                            .object()
                                .key("username").value(params[1].toString())
                                .key("pwd").value(params[2].toString())
                                .key("channelID").value(params[3].toString())
                            .endObject()
                        .endObject();
                        StringEntity se = new StringEntity(img.toString());

                get = new HttpPost("https://" + serverIP + ":" + serverPort + "/Service1.svc/auth");
                //get.setHeader("User-Agent", "com.app.new");
                get.setHeader("Accept", "application/json");
                get.setHeader("Content-Type", "application/json");
                get.setEntity(se);

As I explored the error returned with status code 415, the request somehow was not accepted by the WCF service as valid JSON, therefore by adding the following attribute in svc markup did the trick

Factory="System.ServiceModel.Activation.WebServiceHostFactory"

Here is the complete markup

<%@ ServiceHost Language="C#" Debug="true" Service="IntermediateWebService.Service1" CodeBehind="Service1.svc.cs"
Factory="System.ServiceModel.Activation.WebServiceHostFactory" %>
