我要拔头发了!在上周的某一时刻，我进行了这项工作。

我有一个 Android 应用程序，我正在尝试将应用内计费添加到其中。我遵循示例 TrivialDrive，并且我的代码运行了几次。现在不是了。

我正在创建一个简单的问答游戏，其中有许多免费问题，并且可以选择升级以获得更多问题。当用户完成免费问题列表时，他们将被带到“游戏结束”屏幕，在那里他们可以清除他们的答案并重新开始或升级。

当我点击“升级”按钮时，我可以成功购买，但一旦 Google 的“付款成功”对话框消失，我的 Activity 就会被销毁，我会被送回我的主要 Activity。

当我尝试返回并再次购买时，我的代码捕获了错误(“您已经拥有该商品”)并进行了适当处理。我的代码向用户解释他们已经拥有升级，并允许他们单击按钮继续播放。所以看起来 OnIabPurchaseFinishedListener 此时正在触发。

我已使用最新文件更新了 Google 帮助程序代码。

非常感谢任何关于在哪里寻找答案的帮助或建议。

谢谢。

这是我的 Activity 的相关代码:

最佳答案

仅供引用:我想我已经弄清楚了 - 对于可能遇到它的任何其他人。

我用来启动“In App Billing”的 Activity 被称为“FLAG_ACTIVITY_NO_HISTORY”。我这样做是因为我不希望用户能够单击以返回到此“游戏结束” Activity 。

但是，这会导致“In App Billing”的问题。因此，请确保您不要尝试从已设置“FLAG_ACTIVITY_NO_HISTORY”的 Activity 中启动“应用内结算”。

我的原始代码:

private void GameOver()
    {
        m_TriviaAppInstance.setGameOver(true);
        Intent gameOver = new Intent(getApplicationContext(), GameOverActivity.class);
        gameOver.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
        startActivity(gameOver);
    }

更新代码:

private void GameOver()
    {
        m_TriviaAppInstance.setGameOver(true);
        Intent gameOver = new Intent(getApplicationContext(), GameOverActivity.class);       
        startActivity(gameOver);
    }
