Answer 1

I ran into this issue after macOS crashed due to a kernel panic during a build of the Android project having this issue. It appears that this is most likely caused by a corrupt gradle cache. You can solve this by doing the following:

• Close Android Studio
• Run gradlew --stop to ensure no gradle daemon is still running
• Delete the .gradle folder at the root of your project
• Open Android Studio and rebuild
