Creating Android and iOS app from react-native

I have created one react-native app using expo and atom editor. It's running fine in android device and iOS simulator but with the help of expo. What I want is to generate Apk(debug) so that I can directly run on device. How can I do it ? I followed this(Dmitry Mugtasimov's answer). should I run all those command inside project folder ? Also I don't find index.js file inside my project folder. Also if someone know how to run on iOS simulator by creating app like file(don't know what is that in Ios because from android background). Please help, thanks

Since you have used Expo to develop your react-native app you can build the android app by going to the project folder and running the bellow command in the terminal 

expo build:android

The building process will take around 5-10 minutes. When your build is done, expo build:status will give you your .apk file url. If not, it will say your build is still in progress and to try again later.

Also to build the iOS app you can run,

expo build:ios

To build the iOS standalone app you will need to have an Apple Developer account, but for Android standalone app you don't need a Google Play Developer account.

For the above commands to work you need to have expo-cli installed, For this you can run the bellow command,

npm install -g expo-cli

More Info: https://docs.expo.io/versions/latest/distribution/building-standalone-apps/

If you don't have an Apple Developer Account. You can build the iOS standalone simulator build using the command,

expo build:ios -t simulator

And then wait for build to finish then download and unpack YourAppName.tar.gz. Then, start the iOS simulator and run xcrun simctl install booted YourAppName.app to run the .ica file.

More info: Expo / React-Native, Is it there a way to test-run standalone iOS apps on a device/simulator?
