不一定要在 facebook 应用中心创建一个应用来在墙上（或等）发布消息。我也在创建一个支持 facebook 的游戏，它正在发布带有链接和标题的照片，但游戏没有针对同一问题添加到 facebook 应用中心。
首先，我在https://developers.facebook.com/apps 上创建了一个应用程序，我们应该记住 AppId（API KEY），而不是为 Android 标签启用应用程序并输入哈希码。使用命令keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64 由您的密钥库生成哈希码，其中“androiddebugkey”是您的密钥名称（用于导出），“~/.android/debug.keystore”是您的密钥库（用于导出 ofc）。
