Any ideas what this error means?

When I try and run, npm run playground-android, I get the error.

FAILURE: Build failed with an exception. What went wrong: Execution failed for task ':app:processDebugResources'. java.io.IOException: Could not delete path 'C:\sites\ReactMatt\lower-your-drinking\android\app\build\generated\source\r\debug\org\webkit'.

Any ideas?

I had this same problem but gradlew clean did not resolve issue until I removed the android and ios folders from my project and then used these commands;

  • react-native eject
  • react-native link
  • react-native run-android

good luck.
