Adb backup is not working on Oreo. The created backup file does not contain useful data and is 47 bytes in size. As a quick workaround, I removed the line
android:backupAgent="ShoppingBackupAgent"
from AndroidManifest.xml.
This seems to fix the issue: I successfully created a backup and restored it; seems to contain all necessary data. Not sure if anything relevant got left behind in ShoppingBackupAgent.java.
