安卓应用内订阅 : Inventory call returns purchase as null even if purchase exists

Question

这个问题与Purchased subscription not returned in inventory非常相似& Android billing - error you own this item但他们提供的答案并没有解决我的问题。

我有来自 https://code.google.com/p/marketbilling/ 的最新代码.我签名的 apk 安装在设备上，并作为草稿上传到 Play 商店。我的订阅购买存在于 Google Wallet Merchant Center 中并显示在 queryPurchases 和 queryInventoryAsync 中，但它在我的 PurchaseActivity 中显示为 null。

此代码来自 IabHelper.java 中的 queryPurchases 方法并显示购买信息:

        for (int i = 0; i < purchaseDataList.size(); ++i) {
            String purchaseData = purchaseDataList.get(i);
            String signature = signatureList.get(i);
            String sku = ownedSkus.get(i);

            logDebug("Purchase Data: "+purchaseData);

            if (Security.verifyPurchase(mSignatureBase64, purchaseData, signature)) {
                logDebug("Sku is owned: " + sku);
                Purchase purchase = new Purchase(itemType, purchaseData, signature);

                logDebug("Purchase Data: "+purchase);

                if (TextUtils.isEmpty(purchase.getToken())) {
                    logWarn("BUG: empty/null token!");
                    logDebug("Purchase data: " + purchaseData);
                }

                // Record ownership and token
                inv.addPurchase(purchase);

                logDebug("Get Purchase Data: "+ inv.getPurchase(sku));
            }
            else {
                logWarn("Purchase signature verification **FAILED**. Not adding item.");
                logDebug("   Purchase data: " + purchaseData);
                logDebug("   Signature: " + signature);
                verificationFailed = true;
            }
        }

此方法“queryInventoryAsync”来自 IabHelper.java 类并返回库存信息:

public void queryInventoryAsync(final boolean querySkuDetails,
                           final List<String> moreSkus,
                           final QueryInventoryFinishedListener listener) {
    final Handler handler = new Handler();
    checkNotDisposed();
    checkSetupDone("queryInventory");
    flagStartAsync("refresh inventory");
    (new Thread(new Runnable() {
        public void run() {
            IabResult result = new IabResult(BILLING_RESPONSE_RESULT_OK, "Inventory refresh successful.");
            Inventory inv = null;
            try {
                inv = queryInventory(querySkuDetails, moreSkus);
            }
            catch (IabException ex) {
                result = ex.getResult();
            }

            flagEndAsync();

            final IabResult result_f = result;
            final Inventory inv_f = inv;
            if (!mDisposed && listener != null) {
                handler.post(new Runnable() {
                    public void run() {
                        listener.onQueryInventoryFinished(result_f, inv_f);
                        logDebug("Result: "+ result_f.getResponse() + " inventory: "+ inv_f.getAllOwnedSkus().get(0));
                    }
                });
            }
        }
    })).start();
}

这是来 self 的 PurchaseActivity:

IabHelper.QueryInventoryFinishedListener mInventoryListener = new IabHelper.QueryInventoryFinishedListener() {
    public void onQueryInventoryFinished(IabResult result, Inventory inventory) {

        // Is it a failure?
        if (result.isFailure()) {
            Log.i(TAG, "Failed to query inventory: " + result);
            return;
        }else{
            //This returns false
            Log.i(TAG, "Query inventory was successful: " + inventory.hasPurchase(sku)); 
        }

        // Do we have the premium upgrade?
        //This returns null
        Purchase premiumPurchase = inventory.getPurchase(sku);

尽管 queryPurchases 和 queryInventoryAsync 显示我的设备和电子邮件帐户存在购买，但 getPurchase(sku) 将 Purchase 显示为 null，而 hasPurchase(sku) 返回 false。

有人知道为什么会这样吗？谢谢!

我遇到了同样的问题，并通过这种方式解决了

• 将应用草稿上传为带有一些版本代码的 alpha 或 beta。
• 使用有效订阅的帐户登录设备。
• 在此设备上安装与 alpha/beta 版本相同的已签名应用程序。
