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

For me, "rm -rf android/app/build/" worked

Answer 2

In my case, I've forgotten to add Sudo. Fixed as follows,

sudo npx react-native run-android

Answer 3

I think one more simple thing you could have checked, is if previously you ran the project as different role of a user, like in windows if you ran previously the react-native run-android with an administrator role.

Answer 4

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

Answer 5

I know it is an old question but any of those solutions did not work for me and maybe there are others like me. I solved my problem running this command before run-android

react-native eject

Answer 6

Remove the file: React Native Project Root Directory and locate android -> app -> build -> intermediates -> signing_config -> debug -> out -> signing-config.json .
