Cannot find entry file index.js - React Native

Question

I have basic React Native app. I am trying to test it in virtual Android device. I am navigating to the project and type npm start -- --reset-cache. I kill the proccess and I am typing react-native run-android. I have active Android device, but I see on it this error:

The development server returned response error code: 404 URL: http://10.0.0.2.2:8081/index.bundle?platform=android&dev=true&minify=false Body... "Cannot find entry file index.js in any of the roots:[\"c:\\projects\\HelloRN]"....

I have index.js in the root of the project. Metro Bundler is running on port 8081, but I see same error from it. I am using React Native 0.51.0.

Does native not use the public/src folder structure? I don't know native - sorry if this is misleading. — Aaron

There are two possible solutions:

index.js file isn't in the project root
react-native, in some cases, can't read index.js because try to find index.ios.js and index.android.js, so, duplicate index.js and rename to index.android and index.ios.js

The problem was with permissions. When I create same project in another partition, but not in the C: partition, where Windows is installed, it works fine and it founds index.js file.
