Hello All,

I'm working on Android socket client application, and Server is developed in Java.
My socket client is running on ANDROID EMULATOR (Macintosh) and Server is Running on PC.(Macintosh)

Socker client app get IP address and message from Edit Test and will be sent on button, Here is the code. On button click I'm getting IOexception at `sock.connect(sockaddr);`, Why I'm getting this ?
`Log.i("MyApp", "sockaddr: "+addrs.toString() ); is /10.30.114.14:6666` is it because of extra '/' character before IP !?
Server is okay, I have tested with Telnet .


I have permissions in manifesto file

<uses-permission android:name="android.permission.INTERNET" />

I appreciate your support, Thanks.
