android - IabHelper 购买FinishedListener

Question

如果我通过标准发送购买意向

String mySku = "android.test.purchased";

mHelper.launchPurchaseFlow(this, mySku, 10001, mPurchaseFinishedListener);

我可以购买该项目，它会存储，我可以查询该项目，这也很好。唯一不起作用的是 PurchaseFinishedListener。我的代码与示例应用程序几乎相同，但它似乎根本没有被调用。

12-12 01:40:47.248: D/IabHelper(23502): Calling getPurchases with continuation token: null
12-12 01:40:50.116: D/IabHelper(23502): Starting async operation: launchPurchaseFlow

这是最后两个被调用的方法，之后当我完成购买时它不会调用purchasefinishedlistener

IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener = new OnIabPurchaseFinishedListener() {

    @Override
    public void onIabPurchaseFinished(IabResult result, Purchase purchase) {
        Log.d(TAG, "Purchase finished: " + result + ", purchase: "
                + purchase);
        if (result.isFailure()) {
            complain("Error purchasing: " + result);
            // setWaitScreen(false);
            return;
        }

        if (purchase.getSku().equals(mySku)) {
            Log.d(TAG, "mySku is being consumed.");
            mHelper.consumeAsync(purchase, mConsumeFinishedListener);
        }
        Log.d(TAG, "Purchase successful.");
        new AsyncQuestionsActivity().doInBackground();
    }
};

从日志到最后没有任何效果。有什么我只是想念的东西吗？

我发现了如何解决它。在onActivityResult 中实现handleActivityResult。它需要在听众和已启动的购买流程之间架起一座桥梁。

下面是我使用的代码:

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        Log.d(TAG, "onActivityResult(" + requestCode + "," + resultCode + ","
                + data);

        // Pass on the activity result to the helper for handling
        if (!mHelper.handleActivityResult(requestCode, resultCode, data)) {
            super.onActivityResult(requestCode, resultCode, data);
        } else {
            Log.d(TAG, "onActivityResult handled by IABUtil.");
        }
    }
