WCF と Android を使用するのはこれが初めてです。だから、たぶん簡単な質問でごめんなさい:)
これはwcfサービスライブラリからのものです：
[ServiceBehavior]
public class CheckInService : ICheckInService
{
public string Hello()
{
return "Message from WCF!";
}
}
[ServiceContract]
public interface ICheckInService
{
[OperationContract]
[WebInvoke(
Method = "POST",
UriTemplate = "Hello",
BodyStyle = WebMessageBodyStyle.WrappedRequest,
ResponseFormat = WebMessageFormat.Json,
RequestFormat = WebMessageFormat.Json)]
string Hello();
}
これは、wcf サービス Web サイト Service.svc からのものです。
<%@ ServiceHost Language="C#" Debug="true" Service="TYT.Service.CheckInService" %>
これは、wcf サービス ライブラリ プロジェクトの app.config です。
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.web>
<compilation debug="true" />
</system.web>
<!-- When deploying the service library project, the content of the config file must be added to the host's
app.config file. System.Configuration does not support config files for libraries. -->

<serviceDebug includeExceptionDetailInFaults="False" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>
これは、wcf サービス Web サイトの Web 構成です。

<system.web>

</system.web>
<system.serviceModel>

アンドロイドコード
private final static String SERVICE_URI = "http://10.0.2.2/tytservice/Service.svc";
try {
// Send GET request to <service>/GetPlates
HttpGet request = new HttpGet(SERVICE_URI + "/Hello");
request.setHeader("Accept", "application/json");
request.setHeader("Content-type", "application/json");
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpResponse response = httpClient.execute(request);
HttpEntity responseEntity = response.getEntity();
// Read response data into buffer
char[] buffer = new char[(int)responseEntity.getContentLength()];
InputStream stream = responseEntity.getContent();
InputStreamReader reader = new InputStreamReader(stream);
reader.read(buffer);
stream.close();
String data = new String(buffer);
しかし、データ文字列で取得できるのは、次のエラーを含む HTML ドキュメント全体だけです。

ブラウザでナビゲートするとhttp://localhost/tytservice/Service.svcサービスの説明が表示されますが、追加するhttp://localhost/tytservice/Service.svc/Helloと再び 404
