我正在使用Facebook SDK将数据从应用程序上传到用户Facebook墙。
我已经实现了允许用户通过对话框共享数据的代码，或者如果用户没有直接在墙上发布的android FB应用程序，则通过教程https://developers.facebook.com/docs/android/share。
我收到以下错误：

代码是：

uiHelper.onCreate(savedInstanceState);
//call face book dialog to share data from dive

确定如此遵循FB上的共享教程，但没有包含登录会话过程，因为在教程中并不清楚。
在线分配的教程也已过时（FB SDK ver＆lt; 3.6）。
所以对于像我这样的人来说，这是一个非常好的教程，用于实现最新版本3.6 Dec 10th 2103 FB SDK：
http://code2care.org/pages/android-facebook-sdk-3.6-tutorial-integration-with-your-app/
希望有人觉得有用。

您必须在applicationId中定义AndroidManifest.xml
像这样：
<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/app_id"/>
其中<application android:label="@string/app_name"....是app_id中的字符串。
