This video shows how to fix the import error and the gradle error so the app can run in android studio. The instructions can be found at the GitHub link https://github.com/udacity/ud843-Quak... . This app is from the Udacity Nanodegree android basic course at https://www.udacity.com/course/androi...
I figure I would do a video since it took be about 5 hours of Googling to figure it out.
TLDW(Too Long Did not Watch) Solution
Updating the Gradle plug version to 4.1.0 and Gradle Version to 6.5. To do this, click on File then click on Project structure. Change Android Gradle Plugin Version to 4.1.0 and Gradle Version to 6.5 click apply then click Okay. Gradle sync should start automatically.
You will get an error message in the Sync panel (bottom right of the screen). To resolve the error message click on the blue link that says, "Add google Maven repository and sync project." Click on the Do refactor button(bottom left hand of the screen). Gradle sync should automatically start now. Voila, you should be able to build and run your application now.
