SignalR推送服务在Android的实现 SignalA

SignalA是老外写的用于实现.net端推送消息至安卓端的实现，支持版本为android 2.3或以上，由于我的版本最低是2.2，所以只有把源码下下来自己改，如果你觉得太多了可自己编译成jar引用，本人不才，对java不是很熟悉，如果此版本中有错误还请大家指出来，此图显示的是安卓2.2与4.0的版本。

chat_hub代码：

1. <?xml version="1.0" encoding="utf-8"?>
2. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
3. android:layout_width="match_parent"
4. android:layout_height="match_parent"
5. android:orientation="vertical" >
6. <EditText
7. android:id="@+id/chat_text"
8. android:layout_width="match_parent"
9. android:layout_height="match_parent"
10. android:layout_margin="20dp"
11. android:gravity="top"
12. android:inputType="textMultiLine"
13. android:text="" />
14. </LinearLayout>

SignalR服务器端代码参照http://www.asp.net/signalr来写

SignalA修改过后源码下载
