Download the Affirmations app code using the URL provided from the link above.
The app has two branches - main and starter. The main branch is the final working version of the app which shows a scrollable list of affirmations and images. The starter branch is the starter code that will be developed in stages as the codelab progresses and should end up looking like the final version. Initially the starter code shows a blank white screen when it runs.
This short video shows how to move from the main branch to the starter branch and back using the Git menu in Android Studio.
