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

I did like this... Worked !!

1. In the CMD Project root run react-native upgrade.
2. if you are still getting issues, make sure you have react-native in dependencies json in package.json, add it if not
3. if you are still getting issues, get the version of react native in cmd using react-native -v and check if the value returned in cmd and package.json are same. update the package.json with the value returned in cmd

Here my problem solved.

Answer 2

In my case i didn't had the right permissions for my project folder.

If this is your case just click with the right button on the folder > Properties > Security > Advanced and then change the ownership of the folder to your user, including the subfolders. That should do it

Answer 3

Open your React Native Project Root Directory and locate android -> app -> build -> intermediates -> signing_config -> debug -> out -> signing-config.json

Delete the file and try again.

Answer 4

I had to restyle my AndroidManifest.xml because I had a syntax error somewhere (I had an extra "/" somewhere). Now it's fixed. Be very careful with your syntax...

Answer 5

I raised this question and answered myself as I thought it will help others who are facing similar issue. I struggled a lot to find out the real reason behind it as the error shown in terminal was not precise.

To resolve the issue please upgrade the react-native package.

1. Go to the Project root.

2. Upgrade the React native package in the Command Prompt by typing :

   react-native upgrade.

3. Then Accept to update all the Files by typing y (Yes) in the Command Prompt.

You should consider using the new upgrade tool based on Git. It makes upgrades easier by resolving most conflicts automatically. To use it: - Go back to the old version of React Native - Run "npm install -g react-native-git-upgrade" - Run "react-native-git-upgrade" See https://facebook.github.io/react-native/docs/upgrading.html
