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

Delete signing-config.json next try again react-native run-android

signing-config.json file Path : android -> app -> build -> intermediates -> signing_config -> debug -> out -> signing-config.json

Answer 2

As a complement, in the case react-native command is not found, you should install react-native CLI:

npm install -g react-native-cli

Then you can follow the steps people said above.

Answer 3

Open Command Prompt as Administrator and goto the project folder, run android(npx react-native run-android)

Answer 4

May be it's too late, I replaced the Android folder from a backup file. It worked for me.

Answer 5

I solved the issue by killing all instances of java.exe with: taskkill /f /im java.exe.

Answer 6

We had this issue because files from android folder gradlew and gradlew.bat (Gradle startup script for the UN*X, Windows respectively) somehow got into the global .gitignore file, and so were not presented on local environments.

Actually running react-native upgrade command restore those files, thus fixing the problem.
