Android Studio - Error:Unable to load class 'org.slf4j.LoggerFactory'

Question

I\'m new in the Android world. I opened studio Android 2.2 and, after creating a new project, I get this error message:

Failed to sync Gradle

Answer 1

Go to File-> Settings -> Expand Build, Execution, Deployment -> Select Build Tools -> Gradle -> Under Project Level Settings Select Use default gradle wrapper. Try Gradle build again and this worked for me.
