Having problem fetching product price at onProductsFetched

[kusyuk]

Hi,

I'm having an "Attempt to invoke interface method 'java.lang.Object java.util.List.get(int)' on a null object reference" on onProductsFetched while trying to fetch prices for both IAPP and SUBS. The pricePro is a non-consumable IAPP and both subs doesn't have multiple offers.

Below is the code snipped:

'public void onProductsFetched(@nonnull List productDetails) {

String product, pricePro, priceSubMontly, priceSubYearly;

           for (ProductInfo productInfo : productDetails) {
                product = productInfo.getProduct();
                pricePro = productInfo.getOneTimePurchaseOfferPrice();
                priceSubMontly = productInfo.getSubscriptionOfferPrice(0,0);
                priceSubYearly = productInfo.getSubscriptionOfferPrice(0,0);

                if (product.equalsIgnoreCase(purchasePro)) {
                    Log.d("BillingConnector", "Product fetched: " + product);
                    Log.d("BillingConnector", "Product price: " + pricePro);
                    purchasePrice = pricePro;
                }
                if (product.equalsIgnoreCase(subMonthly)) {
                    Log.d("BillingConnector", "Product fetched: " + product);
                    Log.d("BillingConnector", "Product price: " + priceSubMontly);
                    monthlyPrice = priceSubMontly;
                }
                if (product.equalsIgnoreCase(subYearly)) {
                    Log.d("BillingConnector", "Product fetched: " + product);
                    Log.d("BillingConnector", "Product price: " + priceSubYearly);
                    yearlyPrice = priceSubYearly;
                }

}`

Only the productInfo.title and productInfo.product are available.

My previous code with Billing V4 worked fine

Help me please!

Hope this can help anyone with same issue, We can get the formattedPrice and priceAmountMicros in subscriptionOfferDetails, not in getOneTimePurchaseOfferPrice as below":

var priceAmountMicros: Long? = null
var price: String? = null
for (subscriptionOfferDetails in productInfo.subscriptionOfferDetails) {
    for (pricingPhases in subscriptionOfferDetails.pricingPhases) {
        price = pricingPhases.formattedPrice
        priceAmountMicros = pricingPhases.priceAmountMicros
    }
}

@duckyngo Thanks dude. For half a day I thought that the error was on my side because I just used sample app code

Things changed, the API changed, latest updates were made by contributors so the sample app could be broken.
Maybe I'll find time to update everything myself.

@moisoni97 Thank you for your quick reply. Maybe you should say this in the README to avoid issues like this?
