I was using google app billing v3. I upgraded it to v4. GetSku() gave an error when I upgraded.
Doing this with getSkus() and "purchase.getSkus().contains(getResources().getString(R.string.Product_ID)) && purchase.getPurchaseState() == Purchase.PurchaseState.PURCHASED" fixed the error.
When I click and open the premium purchase page for the first time, the products and prices do not appear. When I leave the page and enter the 2nd and 3rd time, the products and prices appear. Both in-app product selling and subscription part have the same problem. The codes are the same. I was not having this issue in v3. I had this problem after upgrading to v4. Where could the problem be?
