queryPurchaseHistoryAsync

queryPurchaseHistoryAsync

我正在尝试对我的应用程序实现新的google play计费,并尝试使用queryPurchaseHistoryAsync()方法检索我已经购买的应用程序内产品,并且Purchase列表总是空的,只有0个元素。
代码在我购买商品的设备上运行良好,但是在我的另一个设备上,它有相同的google帐户,它不会返回任何内容。
同样在Documentation中,queryPurchaseHistoryAsync()应该与google同步以获取购买历史记录,但由于某些原因,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();
        }
    }
});

我到底是哪里出了问题?
非常感谢。

最佳答案

在onBillingSetupFinished()之后是否调用了QueryPurchaseHistorySync()?
在对源代码调用onbillingsetupfinished()之前,您似乎确实调用了querypurchasehistoryasync()。
您可以在this doc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() { }
});
