Question

我正在尝试实施应用内付款＆＃39;在我的应用程序中

我修改了示例TrivialDrive应用，一切都运行得很好。现在我试图出售多件物品，但它没有像我预期的那样工作。我对代码进行了一些修改，但显然我做错了。

第一次购买完全没问题。然后在第二次收费后，应用程序崩溃了。在第三次购买时，它收取费用，但它不会在游戏中添加项目。它表现得很奇怪......

我在原始应用中做了一些更改：

我创建了多个项目，将其放入ArrayList：

static final String GOLD_3 = "gold_3";
static final String GOLD_5 = "gold_5";
//and so on
static final ArrayList<String> goods = new ArrayList<String>();


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.buy_screen_layout);

    goods.add(GOLD_3);
    goods.add(GOLD_5);
    //and so on

我为不同的项目创建了多个按钮，并为他们创建了onClickListeners：

         @Override
        public void onClick(View v) {
            Log.d(TAG, "Buy gas button clicked.");
            setWaitScreen(true);
            Log.d(TAG, "Launching purchase flow for gas.");
            String payload = "";
            mHelper.launchPurchaseFlow(BuyScreen.this, GOLD_3, RC_REQUEST, mPurchaseFinishedListener, payload);

        }

仅在不同的项目上有所不同.. gold_5，gold_10等。

我稍微改变了QueryInvertoryFinishedListener，我在周期中控制是否所有购买的物品都消耗了：

    IabHelper.QueryInventoryFinishedListener mGotInventoryListener = new IabHelper.QueryInventoryFinishedListener() {

    public void onQueryInventoryFinished(IabResult result, Inventory inventory) {
        Log.d(TAG, "Query inventory finished.");
        if (mHelper == null)
            return;

        if (result.isFailure()) {
            complain("Failed to query inventory: " + result);
            return;
        }

        Log.d(TAG, "Query inventory was successful.");

        for (String good : goods) {
            Purchase goldPurchase = inventory.getPurchase(good);
            if (goldPurchase != null && verifyDeveloperPayload(goldPurchase)) {
                Log.d(TAG, "We have gold. Consuming it.");
                mHelper.consumeAsync(inventory.getPurchase(good), mConsumeFinishedListener);
                return;
            }

        }

        updateUi();
        setWaitScreen(false);
        Log.d(TAG, "Initial inventory query finished; enabling main UI.");
    }
};

再次在OnIabPurchaseFinishedListener中添加了周期：

    IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener = new IabHelper.OnIabPurchaseFinishedListener() {
    public void onIabPurchaseFinished(IabResult result, Purchase purchase) {
        Log.d(TAG, "Purchase finished: " + result + ", purchase: " + purchase);

        if (mHelper == null)
            return;

        if (result.isFailure()) {
            complain("Error purchasing: " + result);
            setWaitScreen(false);
            return;
        }

        if (!verifyDeveloperPayload(purchase)) {
            complain("Error purchasing. Authenticity verification failed.");
            setWaitScreen(false);
            return;
        }

        Log.d(TAG, "Purchase successful.");

        for (String good : goods) {
            if (purchase.getSku().equals(good)) {
                Log.d(TAG, "Purchase is gas. Starting gas consumption.");
                mHelper.consumeAsync(purchase, mConsumeFinishedListener);
            }
        }



    }
};

再次添加了用户购买项目类型的周期和整理：

IabHelper.OnConsumeFinishedListener mConsumeFinishedListener = new IabHelper.OnConsumeFinishedListener() {
    public void onConsumeFinished(Purchase purchase, IabResult result) {
        Log.d(TAG, "Consumption finished. Purchase: " + purchase + ", result: " + result);

        // if we were disposed of in the meantime, quit.
        if (mHelper == null)
            return;

        if (result.isSuccess()) {

            Log.d(TAG, "Consumption successful. Provisioning.");

            String numberOfGold = purchase.getSku();

            if (numberOfGold.equals("gold_3")) {
                GameData.totalGoldCoins = +3;
            } else if (numberOfGold.equals("gold_5")) {
                GameData.totalGoldCoins = +5;
            } else if (numberOfGold.equals("gold_10")) {
                GameData.totalGoldCoins = +10;
            } else if (numberOfGold.equals("gold_15")) {
                GameData.totalGoldCoins = +15;
            } else if (numberOfGold.equals("gold_20")) {
                GameData.totalGoldCoins = +20;
            }

            saveData();


        } else {
            complain("Error while consuming: " + result);
        }
        updateUi();
        setWaitScreen(false);
        Log.d(TAG, "End consumption flow.");
    }
};

...在saveData()我使用sharedPreferences。所有金币都通过游戏存储在静态变量的特殊类中。

我有预感，我对这些周期做错了（试图消费消费产品或其他无意义的东西）。

任何想法，我到底做错了什么？我可以以某种方式在这个已发布的（alpha）应用程序上打开logCat吗？或者，任何方式，如何测试更快（在实际交易上）然后在最终发布/更新后几个小时？

感谢您的任何想法！
