android - android：Inapp计费：错误响应：7：项目已拥有

Question

我正在学习为我的应用实现应用内计费，例如，人们可以在按下捐赠按钮时捐赠 $。

用户可以多次捐赠，即购买是消耗品。

以下代码来自 TrivalDrive 示例和网络上的一些教程：

代码：

IabHelper mHelper;
static final String ITEM_SKU = "android.test.purchased"; 

@Override
protected void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_in_app_billing);

    buy10Button = (Button) findViewById(R.id.buy10Button); 
    buy15Button = (Button) findViewById(R.id.buy15Button); 
    buy20Button = (Button) findViewById(R.id.buy20Button);      

    String base64EncodedPublicKey = "keykeykey";

    mHelper = new IabHelper(this, base64EncodedPublicKey);


    mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() 
    {
          public void onIabSetupFinished(IabResult result) 
          {
            if (!result.isSuccess()) 
            {
               Log.d(TAG, "In-app Billing setup failed: " + result);
               return;
            } 
            if (mHelper == null) 
            {
                return;
            }          
            Log.d(TAG, "In-app Billing is set up OK");
          }
    });     
}

public void buy10Click(View view) 
{
    mHelper.launchPurchaseFlow(this, ITEM_SKU, 10001,  mPurchaseFinishedListener, "");
}

public void buy15Click(View view) 
{

}

public void buy20Click(View view) 
{

}   

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) 
{
    if (mHelper == null) return;  
    if (!mHelper.handleActivityResult(requestCode, resultCode, data)) 
    {     
        super.onActivityResult(requestCode, resultCode, data);
    }
}

IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener = new IabHelper.OnIabPurchaseFinishedListener() 
{
    public void onIabPurchaseFinished(IabResult result, Purchase purchase) 
    {
        if (mHelper == null) return;
        if (result.isFailure()) 
        {
           // Handle error
               return;
        }      
        else if ((purchase.getSku().equals(ITEM_SKU)))   
        {
           consumeItem();
        }              
    }
};

public void consumeItem() 
{
    mHelper.queryInventoryAsync(mReceivedInventoryListener);
}

IabHelper.QueryInventoryFinishedListener mReceivedInventoryListener = new IabHelper.QueryInventoryFinishedListener() 
{
    public void onQueryInventoryFinished(IabResult result, Inventory inventory) 
    {
        if (mHelper == null) return;
        if (result.isFailure()) 
        {
            // Handle failure
        } 
        else 
        {
            mHelper.consumeAsync(inventory.getPurchase(ITEM_SKU), mConsumeFinishedListener);
        }
    }
};

IabHelper.OnConsumeFinishedListener mConsumeFinishedListener = new IabHelper.OnConsumeFinishedListener() 
{
    public void onConsumeFinished(Purchase purchase, IabResult result) 
    {
        if (mHelper == null) return;
        if (result.isSuccess()) 
        {
            Toast.makeText(InAppBillingActivity.this, "Thank you for your donation!!", Toast.LENGTH_LONG).show();   
        } 
        else 
        {
            // handle error
        }
    }
};

问题：

然而，我不断收到E/IabHelper(13392): In-app billing error: Unable to buy item, Error response: 7:Item Already Owned错误消息，并且 Google Play 的付款对话框没有弹出。

我研究了很多类似的情况，有的建议等几分钟，然后购买会自动重置，但我等了快一个小时，但还是很糟糕。

我还发现有人建议将 IabResult 更改为 public boolean isSuccess() { return mResponse == IabHelper.BILLING_RESPONSE_RESULT_OK; }也返回BILLING_RESPONSE_RESULT_ITEM_ALREADY_OWNEDas isSuccess = true，但我不知道如何修改此类...

如何解决问题？谢谢！！

您购买了“android.test.purchased”但没有使用它。但是，如果忘记立即食用，再食用也不是一件容易的事。我们可以等14天。虚假购买将被自动清除。但这是不可接受的。

我花了很多时间寻找解决方案：

添加此行以获取调试信息。

_iabHelper.enableDebugLogging(true, "TAG");

运行应用程序。在 LogCat 中，您将看到一个 json 字符串，例如

{"packageName":"com.example","orderId":"transactionId.android.test.purchased","productId":"android.test.purchased","developerPayload":"123","purchaseTime":0,"purchaseState":0,"purchaseToken":"inapp:com.example:android.test.purchased"}

手动使用它（将 THAT_JSON_STRING 替换为您的 json 字符串）

    Purchase purchase;
    try {
        purchase = new Purchase("inapp", THAT_JSON_STRING, "");
        _iabHelper.consumeAsync(purchase, new OnConsumeFinishedListener() {

            @Override
            public void onConsumeFinished(Purchase purchase, IabResult result) {
                Log.d("TAG", "Result: " + result);
            }
        });
    } catch (JSONException e) {
        e.printStackTrace();
    }

_iabHelper 是 mHelper。

在这里检查我的以下代码：

我在您的代码中不明白您为什么在购买完成监听器中使用查询库存。当您获得与您请求的 sku 相同的 sku 时，应调用 ConsumeAsync() 方法。

// Callback for when a purchase is finished
    IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener = new IabHelper.OnIabPurchaseFinishedListener() {
        public void onIabPurchaseFinished(IabResult result, Purchase purchase) {
            Log.d(TAG, "Purchase finished: " + result + ", purchase: "
                    + purchase);
            if (result.isFailure()) {
                complain("Error purchasing: " + result);
                return;
            }
            if (!verifyDeveloperPayload(purchase)) {
                complain("Error purchasing. Authenticity verification failed.");
                return;
            }

            Log.d(TAG, "Purchase successful.");

            if (purchase.getSku().equals(SKU_GAS)) {

                 // remove query inventory method from here and put consumeAsync() directly
                mHelper.consumeAsync(purchase, mConsumeFinishedListener);

            }

        }
    };

启动设置方法

// 您忘记在 startSetup 方法中调用查询库存方法。

 mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
                public void onIabSetupFinished(IabResult result) {
                    Log.d(TAG, "Setup finished.");

                    if (!result.isSuccess()) {
                        // Oh noes, there was a problem.
                        complain("Problem setting up in-app billing: " + result);
                        return;
                    }

                    // Hooray, IAB is fully set up. Now, let's get an inventory of
                    // stuff we own.
                    Log.d(TAG, "Setup successful. Querying inventory.");
                    mHelper.queryInventoryAsync(mGotInventoryListener);
                }
            });

QueryInventoryFinishedListener

并检查条件购买是否与您请求的相同不等于 null 并且开发人员有效负载在您的查询库存完成侦听器中也相同。
if (gasPurchase != null && verifyDeveloperPayload(gasPurchase)){
    //code
}

// Listener that's called when we finish querying the items and
        // subscriptions we own
        IabHelper.QueryInventoryFinishedListener mGotInventoryListener = new IabHelper.QueryInventoryFinishedListener() {
            public void onQueryInventoryFinished(IabResult result,
                    Inventory inventory) {
                Log.d(TAG, "Query inventory finished.");
                if (result.isFailure()) {
                    complain("Failed to query inventory: " + result);
                    return;
                }

                Log.d(TAG, "Query inventory was successful.");

                /*
                 * Check for items we own. Notice that for each purchase, we check
                 * the developer payload to see if it's correct! See
                 * verifyDeveloperPayload().
                 */

                // // Check for gas delivery -- if we own gas, we should fill up the
                // tank immediately
                Purchase gasPurchase = inventory.getPurchase(SKU_GAS);
                if (gasPurchase != null && verifyDeveloperPayload(gasPurchase)) {
                    Log.d(TAG, "We have gas. Consuming it.");
                    mHelper.consumeAsync(inventory.getPurchase(SKU_GAS),
                            mConsumeFinishedListener);
                    return;
                }
            }
        };

解释为什么会发生：

每当您购买消耗品时，Google Play 商店将不会在 Google Play 控制台中管理其产品购买详情和其他内容。这就是为什么我们必须调用 consumeAsync() 方法。当我们购买商品时，Google Play 商店会记录已购买过一次的商品，并允许您进行第二次购买。

希望它能解决你的问题。

您可以使用Google Play“财务报告”->“访问您的商家帐户以获取更多详细信息”->“订单”查看和取消任何订单以“消费”。然后你需要重启你的设备。=)

我设法通过重新启动设备来“消费购买”。

我正在使用： implementation 'com.android.billingclient:billing:2.0.0' 并且在购买过程中遇到了同样的错误。

关键是：在启动购买之前，我们应该消耗待处理的购买。

请看下面的代码片段：

    List<String> skuList = new ArrayList();
    skuList.add(THE_IAP_ID);
    BillingClient.Builder billingClientBuilder = BillingClient.newBuilder(context).setListener(new PurchasesUpdatedListener() {
        @Override
        public void onPurchasesUpdated(BillingResult billingResult, @Nullable List<Purchase> purchases) {
             // here we have to check the result ...

        });

        billingClientBuilder.enablePendingPurchases();
        billingClient = billingClientBuilder.build();
        billingClient.startConnection(new BillingClientStateListener() {
        @Override
        public void onBillingSetupFinished(BillingResult billingResult) {
            if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {
                // The BillingClient is ready - query purchases.

                Purchase.PurchasesResult pr = billingClient.queryPurchases(BillingClient.SkuType.INAPP);
                List<Purchase> pList = pr.getPurchasesList();
                for (Purchase iitem : pList) {
                    ConsumeParams consumeParams = ConsumeParams.newBuilder()
                            .setPurchaseToken(iitem.getPurchaseToken())
                            .build();
                    billingClient.consumeAsync(consumeParams, consumeResponseListener);
                }

                // process the purchase
            } else {
                // cancelled or s.e. 
                ...
            }
        }

最好的问候，你玩得开心吗:)
