SDK Tools not working

The Android SDK tools are not working. I have gone through forum after forum and tried all different versions of SDK tools. I have installed Android studio, tried replacing the tools with all typed of versions and still the same error. The path is set correctly, but the issue persists.

Not sure what else to try and i can not update my game until it is fixed.
I currently have the latest version of Unity, with the latest version of SDK tools and still will not work.

same problem, tried both jdk 8 and 9. Can t build for android with unity 2017
