java.net.UnkownHostException.
hh zz
Dear ALL,
I had the following problems when I try the first demo application of notification system test app.
I setup a server in google compute engine with ip address 104.155.95.143. I opened all required ports in the server but still got the following errors.
please help me if you have any idea..
