Java 找不到Android Eclipse源

我试图在我的项目中使用NTLM身份验证，但当我调试时，我收到了这条消息，我在这里被困了几天

可能有什么问题？这是我的代码：

String webserviceUrl = "http://ip/folder/page.xml"; // url of the web service.
    String webserviceIP = "up"; // IP of the server.
    String username = "user"; // Domain username
    String password = "pass"; // Domain password
    String deviceIP = "local"; // Device IP 
    String domainName =   "domain"; // Domain name


    DefaultHttpClient httpclient = new DefaultHttpClient();
    httpclient.getAuthSchemes().register("ntlm", new NTLMSchemeFactory());
    httpclient.getCredentialsProvider().setCredentials(
            new AuthScope(webserviceIP, -1),
            new NTCredentials(username, password, deviceIP, domainName));

    HttpGet httpGet = new HttpGet(webserviceUrl);
    httpGet.getParams().setBooleanParameter(CoreProtocolPNames.USE_EXPECT_CONTINUE, false);

    HttpResponse response = httpclient.execute(httpGet); //ERROR HAPPENS HERE
    String responseXML = EntityUtils.toString(response.getEntity());

注: 我在项目中添加了一个外部jar以使用NTML函数。 我在互联网上批准了这份清单

///EDIT 我遇到了这个问题，我试图从主活动执行代码，关于异步任务：

但是现在我没有找到源代码
