Add the following variable to the top of the MainActivity class.
private boolean isOnboarded;
Add the following code segment to the onCreate method in MainActivity.java after initializing the logging.
// grab the isOnboarded value from the StoreHelper/policies store
isOnboarded = StoreHelper.isOnboarded(getApplication());
LOGGER.debug("onCreate: isOnboarded = " + isOnboarded);
The isOnboarded variable becomes important in the next section in determining whether the restore flow should be taken.
Add the following code to the startOnboardingFlow method in the onSuccess callback after line setContentView(...);.
// save the onboarded status
LOGGER.debug("changing isOnboarded to true");
StoreHelper.setIsOnboarded(getApplicationContext(), true);
// log values from the stores
LOGGER.debug("About to log values from the Passcode Policy Store");
StoreHelper.logStoreValues(((OnboardingContext) result).getPasscodePolicyStore());
LOGGER.debug("About to log values from the Application Store");
StoreHelper.logStoreValues(((OnboardingContext) result).getApplicationStore());
