Android應用程序內訂閱：即使購買存在，庫存調用也會將購買返回為null

Question

此問題非常類似於庫存和Android結算中 未返回的已購買訂閱 - 您擁有此項目時出錯，但其中提供的答案並未解決我的問題。

我有來自https://code.google.com/p/marketbilling/的最新代碼。 我簽名的apk已安裝在設備上，並作為草稿上傳到Play商店。 我的訂閱購買存在於Google電子錢包商戶中心，並顯示在queryPurchases和queryInventoryAsync中，但在我的PurchaseActivity中顯示為null。

此代碼來自IabHelper.java中的queryPurchases方法，並顯示購買信息：

        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”來自IabHelper.java類並返回庫存信息：

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();
}

這來自我的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);

雖然queryPurchases和queryInventoryAsync顯示我的設備和電子郵件帳戶存在購買，但getPurchase（sku）將Purchase顯示為null並且hasPurchase（sku）返回false。

有沒有人有任何想法為什么會這樣？ 謝謝！

我有同樣的問題並以這種方式解決了它

• 使用某些版本代碼將草稿應用程序上載為alpha或beta。
• 使用有效訂閱的帳戶登錄設備。
• 使用與alpha / beta版本相同的版本在此設備上安裝已簽名的應用程序。
