Question

我是Android Facebook app分享的新手，我想使用android进行应用程序共享演示，并使用Faceboook app sharing进行了演示

我已经尝试了一步一步，我的代码如下，但它给了我错误，ApplicatioID Parametere一定不能为null，我有我的appId，但我不知道在哪里传递它作为参数。我的代码是：< / p>

在清单文件中包含元数据标记，如下所示：

   <meta-data android:name="com.facebook.sdk.ApplicationId"
          android:value="YOUR_APP_ID" />

此元数据应该是您的应用程序标记的子项
