Here my solution: (I'm doing this for android)

First command:(Navigation to the Android folder of your react-native project)

cd Android

Second command:

./gradlew clean

Third commmand:

./gradlew cleanBuildCache

I'm not fan of deleting android folder. (I think this not a best approaches)

To generate apk file for production: (First one from /Android)(second one from root project)

./gradlew bundleRelease

Answer 5

Running following commands should do the trick:

sudo rm -rf android/ ios/ #Delete Android and ios folders first...
react-native eject
react-native upgrade //rebuilds android/ios folders
react-native link
react-native run-android
react-native run-ios

Answer 6

Yes, it is safe to delete the Android and IOS folder and you can make it again by following steps:

1.First Method: react-native eject <=0.59.0

React-native had this command in the previous version. Running this command will check if the ios and android directories exist and then rebuild whichever one is missing.

sudo rm -rf android/ ios/

react-native eject // Will create new Android and IOS folder.

react-native link

react-native run-android

2.Second Method: react-native upgrade --legacy true>=0.60.0

Now you should use the react-native upgrade --legacy true command to back up your android folders or ios as the case may be as this command will replace your files.
