android billing:4.0.0 - queryPurchases(INAPP) and purchase.getSku()

Question

I refresh to android billing version 4 and 2 things are not working anymore.

First I have this:

else if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.ITEM_ALREADY_OWNED) {             Purchase.PurchasesResult queryAlreadyPurchasesResult = billingClient.queryPurchases(INAPP); // deprecated             List<Purchase> alreadyPurchases = queryAlreadyPurchasesResult.getPurchasesList();             if(alreadyPurchases!=null){                 handlePurchases(alreadyPurchases);             }         } 

queryPurchases is deprecated.

Second I have this:

void handlePurchases(List<Purchase>  purchases) {     for(Purchase purchase:purchases) {         //if item is purchased         if (PRODUCT_ID.equals(purchase.getSku()) && purchase.getPurchaseState() == Purchase.PurchaseState.PURCHASED)         {             if (!verifyValidSignature(purchase.getOriginalJson(), purchase.getSignature())) {                 // Invalid purchase                 // show error to user                 Toast.makeText(getApplicationContext(), R.string.plus_error, Toast.LENGTH_SHORT).show();                 return;             } 

getSku() was working, but now it is mark as Cannot resolve method getSku() in Purchase

Any ideas how to solve this issues?

From docs:

Summary of changes Added BillingClient.queryPurchasesAsync() to replace BillingClient.queryPurchases() which will be removed in a future release.  Added Purchase#getSkus() and PurchaseHistoryRecord#getSkus(). These replace Purchase#getSku and PurchaseHistoryRecord#getSku which have been removed. 

But I don't know how to apply this new commands in my code above.

If I change getSku to getSkus my if if (PRODUCT_ID.equals(purchase.getSkus()) && purchase.getPurchaseState() == Purchase.PurchaseState.PURCHASED) will say that it is always false. And I have no idea how to use queryPurchasesAsync(), need 2 params now.

Thanks.

As I mentioned earlier in a comment you are comparing a String to a List object, but as chitgoks said it is ArrayList<String> and not List<String> as i assumed. I'm not sure if you would ever get more than one sku-string (since you probably don't order multiple things at the same time?) but either look trough them all to be sure or take a chance and compare PRODUCT_ID with only purchase.getSkus().get(0).

The new async call for purchases seems to require only small changes.

Example of old way to do it:

Purchase.PurchasesResult result = billingClient.queryPurchases(BillingClient.SkuType.SUBS); doSomethingWithPurchaseList(result.getPurchasesList()); 

And this would be the new way to do the same:

billingClient.queryPurchasesAsync(BillingClient.SkuType.SUBS, new PurchasesResponseListener() {         @Override         public void onQueryPurchasesResponse(@NonNull BillingResult billingResult, @NonNull List<Purchase> list) {             doSomethingWithPurchaseList(list);         }     });
