Java 信号R本机Android应用协商失败

我正在尝试创建一个android应用程序，可以连接到我的基本信号中心

这只是一个基本的集线器文件，我想用它来测试一些东西，但到目前为止我运气不好。有人能看看我做错了什么吗？每次我尝试运行它时，我都会遇到以下stackraces：

我已检查服务器和WebSocket是否已启用。

经过几天的努力，我是如何让它工作的：

下载并构建它

下载

将libs文件夹添加到signarclientsdk并放入

java\uwebsocket.jar

你以前建的

在signalr client sdk/build.gradle中替换

编译“org.java websocket:java websocket:1.3.1”

与：

编译文件（'libs/java\u websocket.jar'）

转到此处并找到http://to-ws://url的修复程序，在代码中更改它

构建signalr客户端并将其包含在项目中，您还必须包含在第一步中构建的

java\u websocket.jar

，因此您的gradle文件如下所示：

编译'client.signer.aspnet.microsoft.signer\u client\u sdk\u android:signer client sdk android版本：1.0。0@aar'
编译文件（'libs/signer client sdk.jar'）
编译文件（'libs/java\u websocket.jar'）

不要将任何查询字符串传递给HubConnection，否则它将挂起

---

如果您需要传递头（如授权令牌），您必须修复更多代码，这会有一个请求：

您找到问题的解决方案了吗？我有一个类似的（或相同的）解决方案，您能解释一下为什么用TooTallNate的实现替换websockets实现吗？你能不能说你是否在android中实现了一个可接受的（即生产就绪的）稳定的实现？

public class ChatHub : Hub
    {
        public void Send(string name, string message)
        {
            Clients.All.addNewMessageToPage(name, message);
        }
    }

ListView listView;
    HubConnection connection;
    HubProxy proxy;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        listView = (ListView)findViewById(R.id.listView);

        String[] values = new String[]{
                "Testvalue1",
                "Testvalue2",
                "Testvalue3"
        };

        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_expandable_list_item_1,android.R.id.text1,values);

        listView.setAdapter(adapter);

        connection = new HubConnection("http://www.voffice.nl/chat");
        proxy = connection.createHubProxy("chatHub");
        SignalRFuture<Void> awaitConnection = connection.start();
        try{
            awaitConnection.get();
        }catch (InterruptedException e){
            e.printStackTrace();
        }catch (ExecutionException e){
            e.printStackTrace();
        }



    }
