我正在尝试为我的 android 应用程序安装 Facebook 广告。
遵循https://developers.facebook.com/docs/getting-started/facebook-sdk-for-android/3.0/中解释的指南。我还从https://github.com/facebook/facebook-android-sdk/archive/sdk-version-3.0.1.b.zip下载了 Facebook-android-sdk
如上述指南中所述，对于此集成，我必须在所有活动的onResume()中编写以下代码：
com.facebook.Settings.publishInstallAsync(this, MY_FACEBOOK_APP_ID);
对于上述集成，我需要 Facebook SDK jar。所以我已将上述项目（Facebook-android-sdk）导入到我的 Eclipse IDE 中，并将其导出为 jar 文件。我已将此新 jar 添加到我的 libs 目录中，该目录也包含在我的 android 应用程序的 Java 构建路径（库）中。
完成上述步骤后，当我尝试调试或运行我的应用程序时，我在控制台中收到以下错误：

我对上述错误无能为力，我无法调试/运行我的应用程序。
谁能帮我解决这个问题？
