I've got virtual box installed. And when I look at the host > LAN > ip address is exp://192.168.56.1:19000.
How can I change it without disable the network? because it's my virtualbox ip and my device can't connect to it.
Thanks
You can specify the REACT_NATIVE_PACKAGER_HOSTNAME environment variable to use the correct IP address.
If you're using XDE, then make sure to launch it from your project directory with xde . after you've installed the command line tools.
