Android-确定应用内购买是否成功的方法无法正常工作

Question

我已经能够在我的android应用程序中实现应用内购买（遵循android开发者网站的逐步说明）https://developer.android.com/intl/es/training/in-app-billing/index.html)，但应该用来指示购买是否成功的回调发生了一些奇怪的事情。我收到带有真实和静态产品ID的“Purchase Successful”（购买成功）消息，但我希望看到的更改只有在我通过单击升级按钮再次调用“Iab.QueryInventoryFinishedListener”后才能进行。据我所知，“onIabPurchaseFinished”似乎有问题。我已经尝试过使用下面链接中提供的问题解决方案，但“onActivityResult”也没有奏效。我在一个片段中执行这些操作，没有看到任何错误，但我不确定这是否是问题的一部分。任何帮助都将不胜感激。提前谢谢。

我从未打过电话。

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_game, container, false);

    mHelper = new IabHelper(getActivity(), base64EncodedPublicKey);
    mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
        public void onIabSetupFinished(IabResult result) {
            if (!result.isSuccess()) {
                // Oh noes, there was a problem.
                Log.d(TAG, "Problem setting up In-app Billing: " + result);
            }
            // Hooray, IAB is fully set up!
        }
    });

    return rootView;
}

@Override
    public void onDestroy() {
        super.onDestroy();
        if (mHelper != null) mHelper.dispose();
        mHelper = null;
    }

@Override
public void onClick(View button) {
if (button == upgrade){
        if (upgradeOn) {
            //Button Animation
            final Animation animation = buttonAnimation();
            upgrade.startAnimation(animation);

            upgradeOn = false;

            //Check for upgrade
            mHelper.queryInventoryAsync(mGotInventoryListener);
        }
    }
}

//1.
    //Check For Previous Purchases
    IabHelper.QueryInventoryFinishedListener mGotInventoryListener
            = new IabHelper.QueryInventoryFinishedListener() {
        public void onQueryInventoryFinished(IabResult result,
                                             Inventory inventory) {

            if (result.isFailure()) {
                upgradeOn = true;
            }
            else {
                //Check for previous upgrade
                previousUpgrade = inventory.hasPurchase("android.test.purchased");
                if (previousUpgrade){
                    purchaseSuccess();
                }else {
                    //Continue with new purchase
                    mHelper.launchPurchaseFlow(getActivity(), "android.test.purchased", 811,
                            mPurchaseFinishedListener, "bGoa+V7g/yqDXvKRqq+JTFn4uQZbPiQJo4pf9RzJ"
                                    + ParseUser.getCurrentUser().getUsername());
                }
            }
        }
    };

    //2.
    //Handle Purchase
    public void onActivityResult(int requestCode, int resultCode, Intent data) {

        if (!mHelper.handleActivityResult(requestCode, resultCode, data)) {
            super.onActivityResult(requestCode, resultCode, data);
        }
        if (requestCode == 811){
            Log.e("TEST: ","AAAAHHH!");
            if (resultCode == 0){
                Log.e("TEST","URRGGGHHH!");
            }
        }
    }

    //3.
    //Purchase Complete
    IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener
            = new IabHelper.OnIabPurchaseFinishedListener() {
        public void onIabPurchaseFinished(IabResult result, Purchase purchase)
        {
            if (result.isFailure()) {
                return;
            }
            else if (purchase.getSku().equals("android.test.purchased")) {
                purchaseSuccess();
            }
        }
    };

Answer 1

我能解决这个问题。事实证明，“onActivityResult”必须位于我正在处理的片段的父活动中。我重新定位了它（以及mHelper代码，即setup和destroy），但将代码示例中显示的其他方法保留在我的片段中，并且能够让“onIabPurchaseFinished”调用自定义方法“purchaseSuccess（）；”
