【问题描述】：

我几乎完成了我的第一个应用程序。我有我的应用内购买工作，但事实证明我在消费购买时遇到了问题，因为应该可以无休止地购买该物品。我想我已经编辑了代码以正确使用购买的商品，我将提供代码，以便您在我错了时纠正我。但是即使这段代码现在可能是正确的，我也无法再次在我的测试设备上购买该产品，因为最初购买时它没有被消耗掉。我现在如何消费该产品？这是我更新的代码。

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (!mHelper.handleActivityResult(requestCode, resultCode, data)) {
        super.onActivityResult(requestCode, resultCode, data);
    }
}

IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener = new IabHelper.OnIabPurchaseFinishedListener() {
    public void onIabPurchaseFinished(IabResult result, Purchase purchase) {
        if (result.isFailure()) {
            Log.d("Unlock", "Error purchasing: " + result);
            return;
        } else if (purchase.getSku().equals(SKU_HINTS)) {
            consumeItem();              
        }

    }
};

public void consumeItem() {
    mHelper.queryInventoryAsync(mReceivedInventoryListener);
}

IabHelper.QueryInventoryFinishedListener mReceivedInventoryListener = new IabHelper.QueryInventoryFinishedListener() {
    public void onQueryInventoryFinished(IabResult result,
            Inventory inventory) {

        if (result.isFailure()) {
            // Handle failure
        } else {
            mHelper.consumeAsync(inventory.getPurchase(SKU_HINTS),
                    mConsumeFinishedListener);
        }
    }
};

IabHelper.OnConsumeFinishedListener mConsumeFinishedListener = new IabHelper.OnConsumeFinishedListener() {
    public void onConsumeFinished(Purchase purchase, IabResult result) {

        if (result.isSuccess()) {
            add_hints();
            purchase1.setText("Purchase complete");
        } else {
            // handle error
        }
    }
};

public void onClick(View v) {
case R.id.bUnlockHints:
        mHelper.launchPurchaseFlow(this, SKU_HINTS, 10001,
                mPurchaseFinishedListener, "");
        break;
 }

【解决方案1】：

我想出了答案。我不得不更改 startSetup 方法，以便它立即查询库存。这是我的新代码。

IabHelper.QueryInventoryFinishedListener mReceivedInventoryListener = new IabHelper.QueryInventoryFinishedListener() {
    public void onQueryInventoryFinished(IabResult result,
            Inventory inventory) {

        if (result.isFailure()) {
            // Handle failure
        } 
            // This is the updated part
        Purchase hintPurchase = inventory.getPurchase(SKU_HINTS);

        if (hintPurchase != null) {
            mHelper.consumeAsync(inventory.getPurchase(SKU_HINTS),
                    mConsumeFinishedListener);
        }
    }
};

在这里，我在使用之前检查提示是否已购买。否则我会收到一个错误。

mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
        public void onIabSetupFinished(IabResult result) {
            if (!result.isSuccess()) {
                // Oh noes, there was a problem.
                Log.d("Ultimate Quiz",
                        "Problem setting up In-app Billing: " + result);
            }
            // Hooray, IAB is fully set up!
            // Here I run the queryInventory to check right away if the product has been bought, and consume it if it has.
            mHelper.queryInventoryAsync(mReceivedInventoryListener);
        }
    });
