Initially, I had it working (can compile), but after watching the video here and adding Google Play services in the SDK Tools, things stopped working with:
Error:A problem occurred configuring project ':app'. Could not resolve all dependencies for configuration ':app:_debugApkCopy'. Could not find com.google.firebase:firebase-core:11.2.0. Required by: project :app Could not find com.google.firebase:firebase-core:11.2.0. Required by: project :app
I Googled, and everyone says update the SDK Tools, but I don't see any update options:
Are my SDK tools already the latest? What is causing the error message?
