Today, Google released SDK 6 API 23+.
I tried to create a project with the API 23, but I\'m having the following problem:
Failed to resolve: com.android.supp
As seen in the revision column of the Android SDK Manager, the latest published version of the Support Library is 22.2.1. You'll have to wait until 23.0.0 is published.
Edit: API 23 is already published. So u can use 23.0.0
