信号R原生Android应用程序协商失败 [英] Signal R Native Android app Negotiation Failed
问题描述
我想创建一个Android应用程序，可以连接到我的基本SignalR集线器。
I'm trying to create an android app that could connect to my basic SignalR Hub.
它只是一个基本的集线器的文件，我想测试的东西用，但我没有运气这么远。可能有人看一下东西（S）我做错了吗？每次我尝试运行它，我得到以下stackraces：
Its just a basic Hub file i want to test things out with but I've had no luck so far. Could someone have a look at the thing(s) I'm doing wrong? Every time I try to run it I get the following stackraces:

下面是我的code：
集线器：
public class ChatHub : Hub
{
public void Send(string name, string message)
{
Clients.All.addNewMessageToPage(name, message);
}
}
主要活动（Android的一室公寓）
Main Activity (Android Studio)
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();
}
}
在此先感谢，
Thanks in Advance,

编辑：
我检查了服务器和WebSockets的启用。
I've checked the server and websockets are enabled.
推荐答案
下面是我如何得到它后的奋斗几天的工作：
Here is how I got it working after few days of struggle:
下载 https://github.com/SignalR/java-client ，
替换signalr客户端的SDK / build.gradle
Replace in signalr-client-sdk/build.gradle
编译org.java-的WebSocket：Java的的WebSocket：1.3.1
与
编译文件（库/ java_websocket.jar'）
转到这里，并找到解决的HTTP：//为WS：// URL的 https://github.com/SignalR/java-client/issues/63 ，在code更改
Go here and find fix for http:// to ws:// url https://github.com/SignalR/java-client/issues/63, change it in code
构建signalr客户端，并将其包含在你的项目，你还必须包括 java_websocket.jar ，您构建的第一步，让你的摇篮文件witll看这样的：
Build signalr client and include it in your project, you also have to include java_websocket.jar that you built in first step, so your gradle file witll look like:
编译'client.signalr.aspnet.microsoft.signalr_client_sdk_android:signalr-client-sdk-android-release:1.0.0@aar'
编译文件（库/ signalr-客户sdk.jar）
编译文件（库/ java_websocket.jar'）
compile 'client.signalr.aspnet.microsoft.signalr_client_sdk_android:signalr-client-sdk-android-release:1.0.0@aar'
compile files('libs/signalr-client-sdk.jar')
compile files('libs/java_websocket.jar')
不传递任何查询字符串到HubConnection或将挂!!
如果你需要传递头（如授权令牌），你必须解决一些code，有拉要求是：的 https://github.com/SignalR/java-client/pull/64
If you need to pass headers (like authorization token) you have to fix some more code, there is pull request for this: https://github.com/SignalR/java-client/pull/64
这篇关于信号R原生Android应用程序协商失败的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
