应用内结算不起作用:"IAB Helper未设置"

Question

我尝试在我的应用程序中包含应用内结算并进行测试,基于应用程序计费版本3的"TrivialDrive"示例的整个过程(以及实现IAB文件中提供的未修改版本的IAB文件)演示文稿的"util"子目录),但它对我不起作用 - 在LogCat上,就在应用程序因错误而终止之前,它会显示消息"应用程序内计费错误:操作非法状态(launchPurchaseFlow):IAB Helper未设置. "(在startRegistered()函数被触发后,给我LOG消息"点击注册按钮;启动购买流程进行升级.")...

知道这里出了什么问题吗？

以下是我的代码的相关部分:

Answer 1

的根本问题是,startRegistered()被调用到一个UI用户点击直接回应,而你的IabHelper对象的设置是异步触发,所以直到异步响应经由onIabSetupFinished收到无法得知已经完成().

您的startRegistered()方法由用户单击触发,并且调用launchPurchaseFlow(),这反过来要求IabHelper对象已经完成设置,但是如果用户在收到确认之前单击以触发购买(因为设置失败或者因为用户在绘图时非常快,然后安装将不会完成,并且launchPurchaseFlow()将报告您正在看到的错误.对于你的logcat,延迟是14秒,这通常是足够的时间,但......在这种情况下可能不是.或者,也许出了点问题,无论你等多久,你都不会有任何关联.

在您的logcat中,没有消息指示"已连接结算服务",这是您要完成设置时必须首先发生的事情之一.由于没有发生这种情况,因此您也无法从onIabSetupFinished()中看到任何消息(成功或失败).

由于需要异步响应,这是棘手的事情.一种方法是禁用用于触发购买的按钮,直到onIabSetupFinished()成功返回.这将阻止在成功设置IabHelper对象之前触发购买.当然,如果设置失败,你将有一个无法正常工作的按钮,但至少你可以告诉用户怎么了正常的(通过发出一条消息,表明你正在等待设置完成 - 例如,作为一部分按钮文字).

即使这样,一旦您的购买开始并且用户看到付款对话框,您的应用程序可能会通过onStop()循环,在用户考虑购买时从内存中刷新您的应用程序(因为购买对话框是一部分)谷歌播放,不是你的应用程序的一部分,操作系统可能需要内存来运行它,并可以通过停止你的应用程序获得该内存).这会破坏你的IabHelper()对象,然后必须再次创建和异步设置它.同样,由于这是在onCreate()方法中异步触发的,因此在IabHelper对象的设置完成之前,Google Play服务可以调用onActivityResult()来报告用户的购买操作,因为在onActivityResult()中,您需要要使用您的IabHelper实例,这可能会导致错误.看来你必须为任何事情做好准备.

这应该会给你你正在处理的东西的味道.IAB很难正是出于这些原因 - 异步内容的多个线程(例如,设置与购买相比,Android操作系统操作会阻止您的应用获取内存,很可能是您的应用的Google Play应用购买操作等待获得购买的结果).很多实现的内容(包括TrivialDrive示例)都是片状的,因为它隐含地依赖于你的应用程序保留在内存中,实际上它可能会被回收,或者因为它依赖于竞争条件的一条腿(例如设置)之前完成另一条腿(例如,购买发射)确实如此,等等.

执行purchaseFlow功能时遇到同样的问题.请查看Google示例中的Activity类,特别是该方法protected void onActivityResult(int requestCode, int resultCode, Intent data).你可能忘了实现这一个.此功能对于整个机制在没有故障的情况下工作至关重要.

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    Log.i(TAG, "onActivityResult(" + requestCode + "," + resultCode + "," + data);

    // Pass on the activity result to the helper for handling
    if (!inappBillingHelper.handleActivityResult(requestCode, resultCode, data)) {
        super.onActivityResult(requestCode, resultCode, data);
    }
    else {
        Log.i(TAG, "onActivityResult handled by IABUtil.");
    }
}

编辑:此外,当您的手机上的gmail帐户密码错误时,问题也存在(今天发生在我身上).当然,所有Inapp计费功能都应该在手机上进行测试,但我认为很明显.
