Android Studio 应用内购买配置

Question

我正在为我的应用程序设置应用程序内购买，但卡在了某个特定点。目前我使用的代码如下：

IabHelper mHelper;

protected void onCreate(Bundle savedInstanceState) {

mHelper = new IabHelper(this, base64EncodedPublicKey);  //base64EncodedPublicKey is a string declared earlier and not reposted here.

    mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
        public void onIabSetupFinished(IabResult result) {
            if (!result.isSuccess()) {
                Log.d(TAG, "Failed: " + result);
                Toast.makeText(MainActivity.this, "IAB setup Failed", Toast.LENGTH_SHORT).show();
            } else {
                Log.d(TAG, "Worked");
                Toast.makeText(MainActivity.this, "IAB setup Successful", Toast.LENGTH_SHORT).show();
                final List additionalSkuList = new ArrayList();
                additionalSkuList.add("remove_ad");
                mHelper.queryInventoryAsync(true, additionalSkuList, mQueryFinishedListener);
            }
        }
    });

在这一点上，一切似乎都很顺利。 "Worked" 段代码触发并处理成功。代码此时向mHelper.queryInventoryAsync发送请求，配置如下，在onCreate()之外：

IabHelper.QueryInventoryFinishedListener mQueryFinishedListener = new IabHelper.QueryInventoryFinishedListener() {
    public void onQueryInventoryFinished(IabResult result, Inventory inventory)
    {
        if (result.isFailure()) {
            Toast.makeText(MainActivity.this, "Query Listener Error", Toast.LENGTH_SHORT).show();
            return;
        }

        String removalPrice =
                inventory.getSkuDetails("remove_ad").getPrice();
        Toast.makeText(MainActivity.this, removalPrice, Toast.LENGTH_SHORT).show();
        // update the UI
    }
};

此时Toast触发说"Query Listener Error"，表示if (result.isFailure())已经触发。这就是我被困的地方。它没有给我任何关于为什么会发生这种情况的线索。

在开发者控制台中，这些是我的应用内产品的详细信息：

Name/ID: Remove Ad (remove_ad)   
Type: Managed product 
Last Update: Jul 15, 2015  
Status: Active

我做错了什么？唯一我不太确定的是我是如何声明和使用我的 arrayList，以及我在哪里提交了一个字符串值到 .getPrice();

Answer 1

                            mHelper.launchPurchaseFlow(Activity.this, SKU, 11,
                                    mPurchaseFinishedListener, "mypurchasetoken");

调用此方法并实现如下所示的监听器，您将获得结果

public IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener = new IabHelper.OnIabPurchaseFinishedListener() {
    public void onIabPurchaseFinished(IabResult result,
            Purchase purchase)
    {
        if (result.isFailure()) {
            }
            return;

    }
};
