如何在Android Studio 1.0.1上运行Facebook示例应用程序

Question

我一直在尝试运行Facebook SDK示例应用程序（Scrumptious，FriendPickerSample等），但无济于事。 我在Facebook SDK文件夹中有一个名为“samples”的文件夹，我作为项目导入。 然后，我就可以在Android Studio窗口中运行任何示例应用程序。 但是每当我运行其中一个应用程序时，我会得到100个错误和12个警告：

这对我来说似乎很奇怪，因为所有这些错误都来自facebook sdk，例如Session.java。 这是我的项目视图的屏幕截图：

提前致谢。

Answer 1

好的，我很安静，但我觉得你的Project没有support-v4库。 它是Facebook用于项目中的片段和广播管理器的库。 您可以使用没有片段的Facebook登录按钮，但建议将其与片段一起使用

只需在Gradle构建依赖项中添加以下行

编译'com.android.support:support-v4:22.0.+'

我认为它应该工作
