react-native run-android
debug
on device emulator and real device connected by usb

on browser console

Changing node_mudules/reaml/.. localhost didn't work
I still have this error for real device, but not emulator.
@yuripinage Did you follow the suggestion about Chrome extensions in http://facebook.github.io/react-native/docs/debugging#debugging-on-a-device-with-chrome-developer-tools
Yeah, but actually resolved with:
adb kill-server && adb root && adb reverse tcp:8081 tcp:8081 && adb forward tcp:8082 tcp:8082 && adb forward tcp:8083 tcp:8083
And also: https://github.com/realm/realm-js/issues/578#issuecomment-314481708
But localhost:8083, instead of localhost:8082
I m still facing this issue any solution i tried all above solution but not work for me
