我尝试编写一个可以登录 facebook 的应用程序。我使用 facebook sdk，所以我导入了 facebook sdk 中的类。

我去 Project-->Proprietes--->Android--->Library add Facebook SDK 但我收到以下错误（对于所有项目，我刚刚在 1.6 更改了 Java 编译器的属性）：

我在这里看到两个问题：

  1. Android 要求编译器合规级别为 5.0 或 6.0。而是找到了“1.7”。请使用 Android 工具 > 修复项目属性。
  2. 在依赖列表中找到2个版本的android-support-v4.jar

第一个问题应该很容易通过简单地按照说明解决。第二个问题也很容易解决。只需确保 Facebook 项目和您自己的 Android 项目都使用相同版本的兼容性库。最简单的方法是将两者都更新到最新版本。
