Project Setup:reading from cache

I don't have enough reputation to comment so I'll post this as an answer.

• After you Invalidate and Restart have you tried Build->Clean Project and rebuilding then syncing again?

• Have you tried restarting your computer to turn of any processes that may keep caches from clearing?

• Have you tried upgrading your gradle version as well (inside your gradle-wrapper.properties)?

• Have you checked if your gradle path is correct at File -> Settings -> Build, Execution, Deployment -> Gradle?

• Have you tried locating your gradlew and doing a gradlew cleanBuildCache?

• Have you tried removing the C:\Users\{Your Username}\.gradle\caches folder?

• Have you tried disabling cache building altogether (will slow down your build and is not recommended)? To do this you have to go to your gradle.properties file and set android.enableBuildCache=false
