Question 34919 in React native Question posted in
The official React Native documentation can be found here.

how to run cloned/github remote react native app, err msg no android

NOTES: Im new in react native and i see there are so many approaches and with this error i thought the developer who built this app build it differently from what i learn so i don’t understand why he didn’t put the android folder

so i just joined a project and im going to run the apps in my pc by cloning it from github but when i try to npx react-native run-android it failed to run and the log is like this

error Android project not found. Are you sure this is a React Native project? 
If your Android files are located in a non-standard location (e.g. not inside 'android' folder), 
consider setting project.android.sourceDir option to point to a new location.
info Run CLI with --verbose flag for more details.

the folder structure is like this

    The files show that the project is created with Expo. Specifically, you have a managed expo project.

    npx react-native run-android would compile an android app from source, with Expo’s managed workflow that’s not needed. You will need the Expo Go App.

    Expo also comes with its own commands to start the bundler. Instead of running npx react-native ... make use of the expo-cli running: npx expo start

    However, in the package.json there is very likely a script called start. In that case, it’s easier for you to run npm start.

    After running this command the expo console opens. Here you can press a to open the app using expo go (or instructions on how to do so).

    Alternatively, you can run npx expo run:android to start the expo go app on android yourself.
