In library Google Play Billing, could someone tell me what the handlePurchase(purchase) part is for? What exactly does she do?

@Override void onPurchasesUpdated(@BillingResponse int responseCode,
    List<Purchase> purchases) {
if (responseCode == BillingResponse.OK
        && purchases != null) {
    for (Purchase purchase : purchases) {
        handlePurchase(purchase);
    }
} else if (responseCode == BillingResponse.USER_CANCELED) {
    // Handle an error caused by a user canceling the purchase flow.
} else {
    // Handle any other error codes.
} }

It is a mandatory function for the purchase process or, in fact, the purchase has already occurred and I could do anything (notify, open a warning window, consult purchase and etc.)?

What does this part mean?

Since the onPurchasesUpdated method arrived at the handlePurchase() method call means that the purchase has already been made and processed successfully in the Play Store (hence responseCode == BillingResponse.OK && purchases != null ).

So, as you yourself imagined, the handlePurchase() method is just a method to do post purchase processing, from there you can display an alert, save the data in a local DB, send the purchase data to a backend etc. .
