Android 应用内计费v3工作错误

我在我的应用程序中添加了应用程序内计费v3，当我尝试购买一件物品时，转账成功并从信用卡中取款，但该物品没有添加到应用程序中。有什么不对劲吗

好的，首先请在代码中输入日志。。。（日志d（…）

可能您的分数不会写入首选项中，因为计费过程正在另一个过程中。。试试这个

SharedPreferences yourPrefs= ctx.getSharedPreferences(ctx.PREFS_NAME,ctx.MODE_MULTI_PROCESS);

我的应用程序没有满足我的要求。。有什么不对劲吗？请提供更多信息！！这里有一个关于应用内付费v3和购买物品的教程，我想添加代码，但我不能。我可以给你我代码的链接吗？当然可以。。发布链接Alexander Sidikov，感谢编辑。那么，我应该改变什么呢？如果我将“…editor.putin（…）…”替换为“mHelper.launchPurchaseFlow”之后的方法“OnCkickBuy30”，这里的“if（result.issucess（））{score\u get=score\u get+500；}将是这样，或者它也不会工作？
