React native: Android project not found. Maybe run react-native android first?

Question

I had an issue in my React-Native project which was working fine earlier but suddenly it stopped working. Whenever I used the command:

react-native run-andro         


        

Answer 1

My working solution is below, none of the above worked for me:

CD into your project folder and type expo start --android.

Or the long way:

1. Open AVD manager in Android Studio and run a virtual device (you can close AS afterwards)
2. CMD into your project folder and type 'expo start'
3. Once Expo has started choose option 2 which is "Press a for Android emulator"

It will install expo on the virtual device and you can test from there
