When I tried to Live layout editing running option to view on device over wi-fi, firewall came up asking me if i want to let third party on computer i denied access. Now when i try to connect on phone there is error message show up on th phone ''Can not find the Intel XDK. Make sure your device and intel XDK are on the same wireless network. You can update your intel XDK IP address by gong to Test->Wifi and click 'Update Server', so I done all that and still i cant. I thin I should change something with Firewall but i don't know what.
The documentation on live layout provides detailed information on the setup required: https://software.intel.com/en-us/xdk/docs/using-live-development
As for the firewall issue, you can either disable your firewall and try again or allow access for Intel XDK.
To allow access for Intel XDK in Windows, Control Panel -> System and Security -> Windows Firewall -> Allowed Apps (this is in Windows 8.1. Might change slightly depending on your OS). Check 'nw.exe'.
