purchase.on(purchase.transactionUpdatedEvent) is never called

[swissdude]

Hi

First an foremost: THANKS FOR THIS PLUGIN!

Alas, it doesn't really work for me.

Created a Class for the whole process.

The init-works, getProducts() works as well and when I call makePurchase(), I get the console-output that the purchase can be made.

But then it stops. purchase.on(purchase.transactionUpdatedEvent …) is never called.

const purchase = require("nativescript-purchase");
const Product = "nativescript-purchase/product";
//let purchase = new Purchase();
const purchaseInitPromise = purchase.init(["com.myApp.appsubscription"]);

const { Transaction, TransactionState } = require("nativescript-purchase/transaction");
const applicationSettings = require("application-settings");

class inAppPurchaseClass {

    listProducts(callback) {

        purchaseInitPromise.then(() => {

            purchase.getProducts().then((products) => {
                // products.forEach((product) => {
                //     console.log(product);
                // });

                //console.log(products);

                callback(products);
            });
        });
    }

    makePurchase(product, callback) {

        console.log("attempting purchase");

        if (purchase.canMakePayments()) {
            console.log("can make payments");

            purchase.on(purchase.transactionUpdatedEvent, (transaction) => {
                console.log("yo");
                console.log("transaction");
            });

            // NOTE: 'product' must be the same instance as the one returned from getProducts()
            purchase.buyProduct(product);
        } else {
            callback("error");
        }
    }

    setTransactionEventsHook(callback) {

        let result;
        let doConsume = false;
        console.log("init purchase-callback");
        purchase.on(purchase.transactionUpdatedEvent, (transaction) => {

            console.log("transaction hook");

            if (transaction.transactionState === TransactionState.Purchased) {
                //alert(`Congratulations you just bought ${transaction.productIdentifier}!`);
                console.log(transaction.transactionDate);
                console.log(transaction.transactionIdentifier);
                applicationSettings.setBoolean(transaction.productIdentifier, true);
                result = {
                    result: "ok",
                    product: transaction.productIdentifier,
                    trDate: transaction.transactionDate,
                    trId: transaction.transactionIdentifier
                };
            } else if (transaction.transactionState === TransactionState.Restored) {
                console.log(`Purchase of ${transaction.originalTransaction.productIdentifier} restored.`);
                console.log(transaction.originalTransaction);
                console.log(transaction.originalTransaction.transactionDate);
                applicationSettings.setBoolean(transaction.originalTransaction.productIdentifier, true);
                result = { result: "restored" };
            } else if (transaction.transactionState === TransactionState.Failed) {
                console.log(`Purchase of ${transaction.productIdentifier} failed!`);
                result = { result: "failed" };
            }

            if (transaction.transactionState === TransactionState.Purchased && transaction.productIdentifier.indexOf(".consume") >= 0) {

                doConsume = true;

                purchase.consumePurchase(transaction.transactionReceipt)
                    .then((responseCode) => {
                        console.log(responseCode);
                        callback({ result: "consumed" });
                    }) // If responseCode === 0 the purchase has been successfully consumed
                    .catch((e) => console.log(e));
            }

            if (doConsume === false) {
                callback(result);
            }
        });

    }

}

exports.inAppPurchaseClass = inAppPurchaseClass;

I'm calling it from my main-js like this:

iap.setTransactionEventsHook(iapPurchaseCallback);
iap.makePurchase(selectedProduct, iapPurchaseCallback);

As I said, this call works: iap.listProducts(iapCalllback);

I might have to add that I'm trying to buy a subscription. I read the other issues about this, but they all seem kinda outdated, so I'm not sure if this feature works or not.

Android, NS 7.x, v2.0.14 of your plugin

Nevermind - I just realised that I'm using an old version and probably should use the pro-plugins feature...
