应用内结算:"可以购买的查询项目"返回0项

我正在尝试为我的应用实施应用内结算功能.
我正在关注谷歌的TriviaDrive示例应用程序中使用的实现,以及开发人员网站上的相关文档.
我的代码按预期工作,但当我尝试"查询可供购买的项目"时,生成的Inventory对象包含0个对象,即使我已经创建了一个产品.

我paid_version使用Google Play开发者控制台创建了一个带有ID的托管产品,如下图所示:

文档指出"要检索产品详细信息,请调用queryInventoryAsync(boolean, List, QueryInventoryFinishedListener)IabHelper实例."

在我自己的代码中,我调用
mHelper.queryInventoryAsync(true, iabItemSkus, mQueryFinishedListener)
where:
mHelper我的IabHelper实例
iabItemSkus是一个包含单个项目的List,值为"paid_version"
mQueryFinishedListener是我在下面定义的监听器.

IabHelper.QueryInventoryFinishedListener mQueryFinishedListener = new IabHelper.QueryInventoryFinishedListener() {
        @Override
        public void onQueryInventoryFinished(IabResult result, Inventory inv) {
            if (result.isFailure()) {
                Log.d(TAG, "Querying Inventory Failed: " + result);
                return;
            }

            Log.d(TAG, "Title: " + inv.getSkuDetails(SKU_PAID).getTitle());
            Log.d(TAG, "Description: " + inv.getSkuDetails(SKU_PAID).getDescription());
            Log.d(TAG, "Price = " + inv.getSkuDetails(SKU_PAID).getPrice());
        }
    };

但是在调试时我可以看到该Inventory对象在QueryInventoryFinishedListener包含0项中传回,因此调用会inv.getSkuDetails(SKU_PAID).getTitle()给出一个空指针异常.

我无法解决我出错的地方.我期待该Inventory对象包含我paid_version的应用内商品的详细信息.

下面只是我的代码部分和我认为与此问题相关的LogCat(试图避免给你代码重载!),但是如果代码的其他部分的更多细节会有所帮助,请告诉我.

从我的活动:

...
private static final String SKU_PAID = "paid_version";
private static final String TAG = "MyActivity";
private IabHelper mHelper;
...

IabHelper.QueryInventoryFinishedListener mQueryFinishedListener = new IabHelper.QueryInventoryFinishedListener() {
    @Override
    public void onQueryInventoryFinished(IabResult result, Inventory inv) {
        if (result.isFailure()) {
            Log.d(TAG, "Querying Inventory Failed: " + result);
            return;
        }

        Log.d(TAG, "Title: " + inv.getSkuDetails(SKU_PAID).getTitle()); // <-- Line 266 of MyActivity.java
        Log.d(TAG, "Description: " + inv.getSkuDetails(SKU_PAID).getDescription());
        Log.d(TAG, "Price = " + inv.getSkuDetails(SKU_PAID).getPrice());
    }
};
...

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    ...

    final List iabItemSkus = new ArrayList();
    iabItemSkus.add(SKU_PAID);
    // In App Billing
    String base64EncodedPublicKey = "... My Public Key ...";
    mHelper = new IabHelper(this, base64EncodedPublicKey);
    mHelper.enableDebugLogging(true);
    mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
       @Override
       public void onIabSetupFinished(IabResult result) {
           if (!result.isSuccess()) {
               Log.d(TAG, "Problem setting up In-app Billing: " + result);
           }
           // Have we been disposed of in the meantime? If so, quit.
           if (mHelper == null) return;

           // IAB is fully set up. Now, let's get list of available items
           Log.d(TAG, "Setup successful. Querying inventory.");
           mHelper.queryInventoryAsync(true, iabItemSkus, mQueryFinishedListener);
       }
    });
    ...
}

PS:我刚刚更新了我的代码以突出显示第266行.

额外

我在上传APK后12小时遇到此问题,正如您从LogCat中看到的那样,它表示"In-app billing version 3 supported"我的应用.
无论我是否将IN-APP PRODUCT的状态设置为活动或非活动状态,问题仍然存在.

现在24小时后,它神奇地决定正常工作.

由此我只能确定这是Google Play的问题,而不是我的代码.
