【问题描述】：

我正在使用：bp.isSubscribed(ID) 来验证我的订阅。但是当我取消订阅时，方法 bp.isSubscribed(ID) 仍然返回 true。我该怎么办？

transDetails.purchaseInfo.purchaseData.purchaseState.toString() 在我从 Play 商店管理订阅中手动取消后，总是返回 PurchasedSuccessfully。

public void checkSubscriptionDetails(){

bp = new BillingProcessor(this, LICENSE_KEY, new BillingProcessor.IBillingHandler() {
            @Override
            public void onProductPurchased(@NonNull String productId, @Nullable TransactionDetails details) {

                Common.printLog("InApp", ":onProductPurchased :" + productId);


            }

            @Override
            public void onPurchaseHistoryRestored() {

            }

            @Override
            public void onBillingError(int errorCode, @Nullable Throwable error) {
           }

            @Override
            public void onBillingInitialized() {


            }
        });


boolean purchaseResult = bp.loadOwnedPurchasesFromGoogle();
// ## purchaseResult is always return FALSE 

        if (bp.isSubscribed(planID)) {

            TransactionDetails transDetails = bp.getSubscriptionTransactionDetails(planID);

            String strDetailsSubsMonth = "OrderID:" + transDetails.orderId +
                    "\nproductId: " + transDetails.productId +
                    "\npurchaseToken: " + transDetails.purchaseToken +
                    "\npurchaseTime: " + transDetails.purchaseTime +
                    "\npurchaseInfo.signature: " + transDetails.purchaseInfo.signature +
                    "\npurchaseInfo.responseData: " + transDetails.purchaseInfo.responseData +
                    "\npurchaseData.purchaseToken: " + transDetails.purchaseInfo.purchaseData.purchaseToken +
                    "\npurchaseData.autoRenewing: " + transDetails.purchaseInfo.purchaseData.autoRenewing +
                    "\npurchaseData.developerPayload: " + transDetails.purchaseInfo.purchaseData.developerPayload +
                    "\npurchaseData.purchaseState: " + transDetails.purchaseInfo.purchaseData.purchaseState.toString();

            String strPurchaseState = transDetails.purchaseInfo.purchaseData.purchaseState.toString();
            Common.printLog("InApp", "Details: " + planID + " >> " + strDetailsSubsMonth + " \n" + "Purchase State :" + strPurchaseState);
        }

}


package com.anjlab.android.iab.v3;

public enum PurchaseState
{
    PurchasedSuccessfully,
    Canceled,
    Refunded,
    SubscriptionExpired
}

订阅取消时我需要返回“Canceled”。

【解决方案1】：

在onCreate() 中启动bp 变量，然后调用loadOwnedPurchasesFromGoogle()。

就我而言！

不知道为什么我们需要多次致电loadOwnedPurchasesFromGoogle()。当我在onCreate() 中打电话给loadOwnedPurchasesFromGoogle() 时，我总是会出错。但是当我打电话给onPause() 和onDestory() 时，我得到了正确的结果，并且我的所有值都得到了更新。

得到loadOwnedPurchasesFromGoogle()true后，我得到更新订阅值！

谢谢我得到了更新数据，但我注意到取消后只更新“autoRenewing”：true/false 但在自动更新计划后没有得到更新的值。 - orderId - purchaseTime { "orderId": "GPA.3346-XXXXX", "packageName": "XXXXX", "productId": "monthly", "purchaseTime": 1570265452385, "purchaseState": 0, "developerPayload": "subs:xxxxxx", "purchaseToken": "**************", "autoRenewing": false }
如何在应用程序端获取更多数据，例如？ { "kind": "androidpublisher#subscriptionPurchase", "startTimeMillis": "1569992364817", "expiryTimeMillis": "1569992959731", "autoRenewing": false, "priceCurrencyCode": "XXX", "priceAmountMicros": "XXXXX", "countryCode": "IN", "developerPayload": "subs:monthly", "paymentState": 1, "cancelReason": 0, "userCancellationTimeMillis": "1569992810284", "orderId": "GPA.XXXX-XXX-7672-59220..0", "purchaseType": 0, "acknowledgementState": 1 }
取消订阅，用户重新购买后，数值会更新！在自动更新时，价值不会更新。如果此答案对您有帮助，请接受作为答案。

【解决方案2】：

服务器端的最佳解决方案获取订阅的实际信息，或者您可以通过 Node.js 配置进行交叉验证。
