Do in the app store. Going to sell the same item more than once, but it's not a subscription so
in google console created a limited product
In the application to make a purchase using a library Checkout of this post https://habr.com/post/233265/.
The library is checking on product type: if the type of in-app, and this product has already been bought, we get the error ITEM_ALREADY_OWNED (as I understand in this case the purchase request to Google not went)
Changed the type of subscription (SUBSCRIPTION) -there is a request to Google, but Google also returns a message indicating that the product is already bought
requests.purchase(ProductTypes.SUBSCRIPTION, "ptoduct", null, mCheckout.getPurchaseFlow());
A limited product Google is not allowed to buy more than once, and the subscription is not suitable for multiple purchases in korotichi period of time
As you can several times to buy the same product?
