我正在拔头发!在上周的某个时候,我有这个工作。

我有一个 Android 应用程序,我正在尝试向其中添加应用内计费。我遵循了示例 TrivialDrive,我的代码运行了几次。现在没有了。

我正在创建一个简单的琐事游戏,其中包含许多免费问题,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,他们会被带到“游戏结束”屏幕,在那里他们可以删除他们的答案并重新开始,或者升级。

当我点击“升级”按钮时,我可以成功购买,但是一旦谷歌“付款成功”对话框消失,我的活动就被破坏了,我被送回了我的主要活动。

当我尝试返回并再次购买时,我的代码会捕获错误(“您已经拥有此商品”)并适当地处理它。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。因此,此时似乎 OnIabPurchaseFinishedListener 正在触发。

我已使用最新文件更新了 Google 帮助程序代码。

非常感谢有关在哪里寻找答案的任何帮助或建议。

谢谢。

这是我活动的相关代码:

仅供参考:我想我已经弄清楚了 - 对于任何可能遇到它的人。

我用来启动“In App Billing”的活动是用“FLAG_ACTIVITY_NO_HISTORY”调用的。我这样做是因为我不希望用户能够单击以返回此“游戏结束”活动。

但是,这会导致“应用内计费”的悲痛。因此,请确保您不要尝试从设置了“FLAG_ACTIVITY_NO_HISTORY”的活动中启动“应用内计费”。

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);
    }

和平

我不够高,无法评论,但祝福你。我有

android:noHistory="true"

为我的活动在 AndroidManifest.xml 中设置并且遇到了同样的问题。

把它拿出来,IAB 正在工作。耶!

不要忘记您的 IabHelper.OnIabPurchaseFinishedListener 是在不同的线程上调用的,并且在 onResume() 之前在您的 Activity 上调用!

因此,您的 UpgradeComplete() 或 UpgradeError() 可能会导致旧设备崩溃(在我的 Gingerbread Sony Xperia Mini Pro 上每次都崩溃,并且在三星 Galaxy S4(Android 4.2.2)上正常工作)

导致我的游戏延迟了 3 天..
