使用 setNavigationBarDividerColor() 时出现 NoSuchMethodError？

Question

当导航栏和我的应用程序内容颜色相同时，我试图在它们之间创建一个分隔线，Google 在他们最新的 Material Design 2.0 更新中就是这样做的到他们的应用程序，例如 Google 联系人和 Google 主页。我试着这样做：

getWindow().setNavigationBarDividerColor(Color.GRAY);

但是，我在尝试时得到 NoSuchMethodError。

我正在尝试找到解决此问题的方法或另一种在导航栏上方放置分隔线的方法。

这是堆栈：
