InAppBilling在啟動時崩潰

Question

我正在嘗試創建一個應用程序，我可以在應用程序購買中獲得簡單的實現。 我一直在關注這個指南http://www.techotopia.com/index.php/Integrating_Google_Play_In-app_Billing_into_an_Android_Application_%E2%80%93_A_Tutorial

但它充滿了可能過時的信息，而忽略了包含您需要從SDK管理器下載的軟件包的所有名稱。 我從這個程序中遇到的主要錯誤似乎是參考錯誤，比如我沒有導入某個庫或兼容性文件丟失了。 我設法在eclipse中解決所有這些問題，並且當我運行代碼但在設備或VM中嘗試它時沒有錯誤，當我嘗試在那里運行時應用程序崩潰。

出於顯而易見的原因，我排除了谷歌播放連接所需的密鑰。

Answer 1

添加Manifest文件的權限

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

還添加到Application節點下的Manifest文件中

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

還要確認您已將InAppBillingActivity.java添加到Manifest文件中。
