我已经包含在我的应用程序gradle这个文件中的以下命令：

编译（名称： 'signalr客户端-SDK-机器人调试'，分机： 'AAR'） 编译文件树（包括：[ '的* .jar']，则dir： '库'）

这两个文件都在我的应用程序目录的libs文件夹中。

可能是什么问题？从this链接

Answer 1

下载的zip，解压然后导入signalr客户端-SDK和signalr客户端-SDK-的Android在您的项目模块。

在您的build.gradle中添加compile project(':signalr-client-sdk-android')。

同步您的gradle这个，然后运行..它会工作

Answer 2

尝试从以下链接下载所有需要的库：

https://drive.google.com/open?id=0B8POMankZlWcNGZ1Zm9td3pDNVk

之后，你应该能够编译所有的.jar文件从您的应用程序模块biuld.gradle文件中。

compile files('libs/signalr-client-sdk.jar') 
compile files('libs/signalr-client-sdk-android.jar') 
compile files('libs/gson-2.2.2.jar') 

现在，您可以在您的android项目中使用所有的SignalR功能。
