Cannot find entry file index.android.js in any of the roots:[ Android ]

Question

I am trying to start my hello world app using react native using windows 7 and an android device. There is a similar issue here but I have failed make it work.

Commands I have run so far to set up and lead to this issue.

Created the app: react-native init helloMe
Moved to the root Dir[helloMe]. react-native run-android
Android Device is set up okay and showing in CMD using adb
Opened another CMD window then ran: react-native start
Ran react-native run-android again.
Red Screen is shown on phone with this error unable to load script from assets index.android.bundle on windows

Trying to fix it with the solution in step 6 leads to another error which is why I am here. below is my CMD log.

E:\testdir\react_ws\helloMe>react-native bundle --platform android --dev false --entry-file index.android.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res
Scanning 558 folders for symlinks in E:\testdir\react_ws\helloMe\node_modules (30ms)
Scanning 558 folders for symlinks in E:\testdir\react_ws\helloMe\node_modules (20ms)
Loading dependency graph, done.
Cannot find entry file index.android.js in any of the roots: ["E:\\testdir\\react_ws\\helloMe"]
E:\testdir\react_ws\helloMe>

Now I am getting another error when I try to fix the problem with the above solution.

Cannot find entry file index.android.js in any of the roots: ["E:\\testdir
\\react_ws\\helloMe"]

If have tried to apply this fix from here

npm run start -- --root <directory_with_your_react_component_js_sources>

I since I am running the command in the project root, I ran this instead npm run start -- --root ./ but it did not work.

This is my root project structure

__tests__  app.json          index.ios.js  node_modules  yarn.lock
android    index.android.js  ios           package.json

I hope I am clear, any help would be highly appreciated. Device is stuck on red screen with a 404.

React-native-version

react-native-cli: 2.0.1
react-native: 0.46.0

Thanks.

Changed the version of react project to a lower one from here

npm install -g rninit

rninit init [Project Name] --source react-native@0.40.0

Worked okay for both on both iOS and Android on . If you get Error Could not get BatchedBridge. run this

adb reverse tcp:8081 tcp:8081

This worked for me.
