Continuing from where we left, reopen the starter project, then build and run your app. You should see the note you just created earlier. Tap Create Note to navigate to the Create Note screen. Fill in the form with the title and description, select a priority, and select External Storage as the note location. Tap Create Note to create the note, but your note won’t save to external storage yet. You’ll implement the read and write operations to external storage in the next steps.
