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

I solve this by following steps

1. download the newest version of gradle in this site: http://download.csdn.net/download/fallingwind/9604349

2. replace folder "disk-label://android-studio/gradle" with the download file(unarchive first).

3. restart AS

4. if it doesn't work, you can change the environment path of gradle.exe

Answer 2

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.
