Gdx-Pay支票购买 [英] Gdx-Pay check for purchases

问题描述

我已经完成了IAP系统的设置，但是我不知道如何检查用户是否真正拥有/已经购买了某种产品. 使用Android的Google IAP帐单，我确实做到了:

I've finished setting up my IAP system but I can't figure out how to check if the user actually owns/have purchased a certain product. Using Google IAP Billing for android I simply did:

Purchase ITEM_1 = inventory.getPurchase(ITEM_1);
if(ITEM_1 != null && verifyDeveloperPayload(ITEM_1)){
//Give user the product
ITEM_1_BOUGHT = true;
}

我在Gdx-Pay中找不到等效的方法.

I can't find an equivalent method for this in Gdx-Pay.

推荐答案

PurchaseObserver具有一个名为:handleRestore(Transaction[] transactions)

您可以遍历交易:

@Override
public void handleRestore(Transaction[] transactions) {
    for (int i = 0; i < transactions.length; i++) {
        // do something with all bought products.

        if (transactions[i].getIdentifier().equals("YOUR_PRODUCT_IDENTIFIER")) {
            // do something with a certain product
        }
    }
}
