Is this a bug report?

Its an issue i am facing while running the normal Awesome Project on my system

Have you read the Contributing Guidelines?

Yes

Environment

1. react-native -v: 0.47.1
2. node -v:8.2.1
3. npm -v:4.1.2
4. yarn --version:

Then, specify:

• Target Platform:
  Android

• Development Operating System:
  Windows 7

• Build tools:26.0.0-rc2

Steps to Reproduce

(Write your steps here:)

1.Open command prompt in Administrator Mode
2.run command: cd
3.run command: react-native init
4.run command: cd
5.run command: react-native run-android
this makes the package server run automatically on port 8081. But I am not able to access the package server from browser on the machine and the mobile.
I tried using http://:port/index.android.js
http://localhost:port
http://127.0.0.1:port

=> I was getting the red screen on both mobile and the emulator with following message:
I tried running the project on real device and on emulator. On Both I got error: "Unable to load script from assets 'index.android.bundle' Make sure your bundle is packaged correctly or you're running a package server'.

reloading i get the error: "Could not connect to development server."

Then i set the host and port number on development setting on both and got the error "Could not connect to development server."

Expected Behavior

The project is expected to run on emulator and phone without any error.

But instead i got the error and i have tried many times and i am getting the same error repeatedly and in same pattern.
