Did you run the adb command like the error says?

Probably have to do adb reverse tcp:8080 tcp:8080

I have the same problem. I'm using MacOSX El Capitan and Android Devices.

Using adb reverse tcp:8081 tcp:8081 worked with my android 5.0+, but I can not run on devices 4.0, what can I do?

On older devices you should set the IP to the packager in the dev settings menu. See https://facebook.github.io/react-native/docs/running-on-device-android.html

Before I run adb reverse tcp:8081 tcp:8081. I get the red screen telling me http://localhostL8081/index.android.bundle?platform=android could not connect to server.

But after I run the adb command. The red screen still tell me could not connect to server.
But disappear the http://localhost section.
And my packager actuall get the request and print the log in the console.
But the red screen still.
