After clean install of Android Studio I always get the error
Error:java.util.concurrent.ExecutionException: java.lang.RuntimeException: No server t
I ran into the same problem, and it turned out I had messed up the file permissions inside the android-sdk folder (more specifically android-sdk/build-tools/{version}), and some binaries were missing execution permissions.
In my case, I simply gave x
