Android Navigation Graph

Using the new Navigation Graph in Android Studio canary 3.2. I've run into the problem where the visual of the nav graph will not render. The display says "Waiting for build to finish..." I've tried rebuilding, cleaning, even uninstalled & reinstalled Android Studio. Nothing seems to fix it. Anyone have any luck? (I get the following IDE error.)

Stumbled upon a solution accidentally.

  1. First of all, delete gradle dependencies of navigation controller as well as all the usages of it in code.
  2. Delete navigation folder in resources.
  3. Make sure gradle sync is successful.
  4. Restart Android Studio.
  5. Right click on res folder, create new resource. Name it nav_graph, select resource type - navigation. AS offers to download needed dependencies, press yes.
  6. Enjoy the navigation controller.

Note that this sequence worked for me not from the first time, retry if it still fails.

Edit: after adding other navigation controller dependencies (ui and navigation testing) and restarting the AS, same bug occurred. After a small experiment I have found the culprit - it is dependency androidTestImplementation "android.arch.navigation:navigation-testing-ktx:$navigationVersion". Just do not use it yet or comment it before exiting AS, uncomment after starting it.
