当我通过Eclipse通过ADB安装我的应用程序时，然后facebook登录以及发布到用户的墙上工作（使用facebook SDK 3.0），但是当我打包我的应用程序然后安装该应用程序时，那么facebook登录不起作用。我通过登录按钮获取片段，当我按下登录按钮时，它会显示应用程序想要访问我的公开个人资料和好友列表的对话框。当我单击确定时，它会返回到具有登录按钮的片段。
我的问题是：在部署期间我应该如何更改facebook SDK集成？

我假设您关注了facebook开发者教程。如果是这样，您可以使用此命令生成密钥
keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64
您还必须使用发布密钥库创建密钥并将其注册到Facebook。
