Question

我试图创建一个应用程序，我可以在应用程序购买中获得简单的实现。我一直在贬低本指南http://www.techotopia.com/index.php/Integrating_Google_Play_In-app_Billing_into_an_Android_Application_%E2%80%93_A_Tutorial

但它充满了可能过时的信息，而忽略了包含您需要从SDK管理器下载的软件包的所有名称。我从这个程序中遇到的主要错误似乎是参考错误，比如我没有导入某个库或兼容性文件丢失了。我设法在eclipse中解决所有这些问题，并且当我运行代码但在设备或VM中尝试它时没有错误，当我尝试在那里运行时应用程序崩溃。

由于显而易见的原因，我排除了Google Play连接所需的密钥。

Answer 1

为您的清单文件添加权限

 <uses-permission android:name="com.android.vending.BILLING" />

还会添加到Application节点

下的清单文件中

<meta-data
            android:name="com.google.android.gms.version"
            android:value="@integer/google_play_services_version" />

另外，请确认您已将InAppBillingActivity.java添加到您的清单文件中。
