如何检查是否已购买应用程序-CodenameOne [英] How to check if an app has already been purchased - CodenameOne

问题描述

我的应用程序可以购买我在google开发人员帐户上配置的应用程序内产品。

My application can buy an in-app product which I have configured on the google developer account.

该产品是一次性购买的产品。我想知道如何检查该物品是否已经购买（在codenameone中）并根据查询结果进行处理。

The product is a buy-once product. I would like to know how to check if this item has already been bought (in codenameone) and handle it based on result of query.

以下是代码摘录：

if(p.isManagedPaymentSupported()) {
        if(p.wasPurchased(id)){
            boolUpdate = true;
            Form f = (Form)createContainer(resPath,"Search");
            beforeSearch(f);
            f.show();
        }else{
            Display.getInstance().callSerially(new Runnable() {
            public void run() {
                   Boolean confirmAction = Dialog.show("Buy Product?","","Yes","No");
                   if(confirmAction){
                       p.purchase(id);
                   }
                }
            });
        }
    }

根据codenameone API文档， p。 wasPurchased（id）方法应该提供此功能。但是在我的设备上安装并购买后，情况并非如此。购买产品后，付款过程将再次开始。

According to the codenameone API doc, The "p.wasPurchased(id)" method is supposed to provide this functionality. But this is not the case after installing on my device and making a purchase. The payment process begins again even after the product has been bought. Meaning the "wasPurchased()" check is returning false.

我想检查商品是否已经购买，并根据该商品转到下一个屏幕，或者开始购买过程。请问我如何在codenameone上实现它？

I would like to check if the item is already purchased and based on that either go to the next screen, or begin the purchase process. Please how can I implement this on codenameone?

谢谢

推荐答案

当前假设Android是不支持您目前所管理的购买平台吗？

Currently managed purchases aren't supported on Android which I'm assuming is the platform you are referring to?

有RFE和一些代码可以解决该问题，但我们没有撰写本文时，请尽量避免这样做： http：// code .google.com / p / codenameone / issues / detail？id = 731

There is an RFE and some code to resolve it but we didn't get around to do it as of this writing: http://code.google.com/p/codenameone/issues/detail?id=731
