购买后AndroidGooglePlay订阅被取消了

可能存在以下问题：

1. 用户可能在未取消订阅的情况下，停止了订阅

2. 支付失败或支付取消

3. 非法客户端行为

为了解决这个问题，可以在以下情况下调用订阅更新服务：

1. 在启动应用程序时查询用户的订阅状态

2. 让用户更新订阅并检查订阅状态

下面是代码示例：

//创建订阅更新服务的Intent Intent updateSubscription = new Intent(Intent.ACTION_VIEW); updateSubscription.setData(Uri.parse("market://details?id=com.example.sampleapp")); startActivity(updateSubscription);

//检查订阅的状态并更新 if(mBillingClient.isReady()){ Purchase.PurchasesResult purchasesResult = mBillingClient.queryPurchases(BillingClient.SkuType.SUBS); if (purchasesResult.getResponseCode() == BillingClient.BillingResponseCode.OK) { List<Purchase> purchasesList = purchasesResult.getPurchasesList(); for (Purchase purchase : purchasesList) { if (purchase.getSku().equals("sub1")) { AcknowledgePurchaseParams acknowledgePurchaseParams = AcknowledgePurchaseParams.newBuilder() .setPurchaseToken(purchase.getPurchaseToken()) .build(); mBillingClient.acknowledgePurchase(acknowledgePurchaseParams, new AcknowledgePurchaseResponseListener() { @Override public void onAcknowledgePurchaseResponse(BillingResult billingResult) { if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) { // 订阅被更新了 } } }); } } } }
