Android-queryPurchaseHistoryAsync购买列表在其他设备上为空

Question

我正在尝试将新的Google Play结算应用到我的应用中，并尝试使用queryPurchaseHistoryAsync()方法来检索我已经购买的应用内商品，并且该Purchase列表始终为0，且元素为空。

该代码在我购买了该商品的设备上运行正常，但是在其他具有相同Google帐户的设备上，该代码什么也没有返回。

就像在文档中一样，queryPurchaseHistoryAsync()应该与Google同步以获取购买历史记录，但是由于某种原因，它似乎不同步。

我的代码是：

BillingClient billingClient = BillingClient.newBuilder(getApplicationContext()).setListener(new PurchasesUpdatedListener() {
    @Override
    public void onPurchasesUpdated(int responseCode, @Nullable List<Purchase> purchases) {
        if(responseCode == BillingClient.BillingResponse.OK) {
            //Do something
        }
    }
}).build();
billingClient.startConnection(new BillingClientStateListener() {
    @Override
    public void onBillingSetupFinished(int responseCode) {
        if(responseCode == BillingClient.BillingResponse.OK) {
            //Response is OK and working fine
        } 
    }

    @Override
    public void onBillingServiceDisconnected() {
        //Do something
    }
});

billingClient.queryPurchaseHistoryAsync(BillingClient.SkuType.INAPP, new PurchaseHistoryResponseListener() {
    @Override
    public void onPurchaseHistoryResponse(int responseCode, List<Purchase> purchasesList) {
        if(responseCode == BillingClient.BillingResponse.OK) {
            //Always returning 0 size() of purchasesList
            Toast.makeText(getApplicationContext(), "There are " + purchasesList.size() + " items you've purchased.", Toast.LENGTH_LONG).show();
        }
    }
});

我在哪里弄错了这段代码？

非常感谢。

您是否在onBillingSetupFinished（）之后调用queryPurchaseHistoryAsync（）？

似乎您在源代码上调用onBillingSetupFinished（）之前先调用queryPurchaseHistoryAsync（）。

您可以在此文档中检查以下代码

private BillingClient mBillingClient;
...
mBillingClient = BillingClient.newBuilder(mActivity).setListener(this).build();
mBillingClient.startConnection(new BillingClientStateListener() {
    @Override
    public void onBillingSetupFinished(@BillingResponse int billingResponseCode) {
        if (billingResponseCode == BillingResponse.OK) {
            // The billing client is ready. You can query purchases here.

        }
    }
    @Override
    public void onBillingServiceDisconnected() { }
});
