如何在Android 4.1和4.2上調試應用內結算？

Question

我是Android開發人員的新手，我遇到了一個非常煩人且熟悉的問題。

簡短版本 ：如何在不購買物理設備的情況下測試我的應用程序？ 具體來說，我正在嘗試在4.1和4.2運行的設備上進行測試。 我不能使用模擬器，因為這涉及應用內結算。

長版 ：

今天，我收到了用戶的崩潰報告（Android版本= 4.2，設備= A1-811（芒果））。

問題是： 未設置IAB幫助程序。 無法執行操作：queryInventory 。 我在4.3、5.0、5.1上測試了該應用程序，這很好。

我知道發生了實際的崩潰，因為我在mhelper.startSetup（）中檢查（！result.isSuccess（））時沒有退出。

我的問題是，如何解決未設置IabHelper的根本問題？ 我無權使用Android 4.2設備...

我的密碼：

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

                if (result.isFailure ()) {
                    Log.d (PURCHASE_TAG, "Google's response is a failure.");
                } else {
                    Log.d (PURCHASE_TAG, "Response is successful. purchase.getSKU = " + purchase.getSku ());
                    premium = true;
                }
            }
        };

        IabHelper.QueryInventoryFinishedListener mQueryFinishedListener = new IabHelper.QueryInventoryFinishedListener () {
            public void onQueryInventoryFinished (IabResult result, Inventory inventory) {
                Log.d (PURCHASE_TAG, "Processing Google's response.");

                // Check if user has existing purchase.
                if (result.isFailure ()) {
                    Log.d (PURCHASE_TAG, "Google's response is a failure. Response = ");

                } else {
                    Log.d (PURCHASE_TAG, "Google's response is success! getPurchase() = " + inventory.getPurchase (THE_SKU));

                    if (inventory.getPurchase (THE_SKU) == null) {
                        premium = false;
                    } else {
                        premium = inventory.getPurchase (THE_SKU).getSku ().equals (THE_SKU);
                    }
                }

                // Show price if user is not premium, thank you note if the user is premium
                if (premium == true) {
                    Log.d (PURCHASE_TAG, "3 premium = " + premium);
                    priceView.setText ("Thank you for the purchase!");
                } else {
                    if (inventory != null) {
                        String pro_price = inventory.getSkuDetails (THE_SKU).getPrice ();
                        priceView.setText ("" + pro_price);
                    }
                }
            }
        };

        private void startPurchaseQuery () {
            String base64EncodedPublicKey = "the key is generated ...";

            mHelper = new IabHelper (this, base64EncodedPublicKey);

            Log.d (PURCHASE_TAG, "Purchase query started.");

            mHelper.startSetup (new IabHelper.OnIabSetupFinishedListener () {
                public void onIabSetupFinished (IabResult result) {
                    Log.d (PURCHASE_TAG, "IabHelper Setup successful. Querying inventory.");

                    if (!result.isSuccess ()) {
                        Log.d (PURCHASE_TAG, "Error with IabHelper setup.");
return;

                    }

                    if (mHelper == null) return;

                    // IAB is fully set up. Now, let's get an inventory of stuff we own.
                    // Build the SKU list
                    List<String> additionalSkuList;
                    additionalSkuList = new ArrayList<String> ();
                    additionalSkuList.add (THE_SKU);
                    // Make the query
                    mHelper.queryInventoryAsync (true, additionalSkuList, mQueryFinishedListener);

                    Log.d (PURCHASE_TAG, "Query finished. Premium status = " + premium);
                }
            });
        }


    @Override
    protected void onActivityResult (int requestCode, int resultCode, Intent data) {
        Log.d (PURCHASE_TAG, "onActivityResult(" + requestCode + "," + resultCode + "," + data);

        // Pass on the activity result to the helper for handling
        if (!mHelper.handleActivityResult (requestCode, resultCode, data)) {
            // not handled, so handle it ourselves (here's where you'd
            // perform any handling of activity results not related to in-app
            // billing...
            super.onActivityResult (requestCode, resultCode, data);
        } else {

        }
    }

上面評論的答案

最好先捕獲錯誤並修補自己的代碼。 嘗試重現為什么未設置IAB的確切問題可能是不可能的，因為用戶可以在其設備上進行各種修改（可能是特定版本的發行版用戶正在運行的錯誤，這幾乎是找不到的，或者類似）。 如您所建議，使用Analytics（分析）找出有多少用戶遇到此問題是個好方法。

要回答原始問題，您可以在開發者控制台中創建Alpha或Beta版本，並將具有特定Android版本的用戶邀請到測試組中。 這是您可以直接從Dev測試問題和崩潰的方法。 即使不直接成為設備所有者，也要進行控制台。
