问题：
为什么这个活动在新的Android版本中显示而不是在旧版本中显示
姬俊驰
我在用Android Studio。
如何使它支持旧版本？

错误只是说Android Studio找不到以下资产文件
fonts/CircularPro-Medium.otf
确认该文件存在于资产目录中的字体文件夹中，然后重新生成项目。

我更新了JDK 1.7_51和JRE 1.7.79。My JAVA_HOME设置为C:\Program Files\Java\JDK1.7.0_51，而JRE_HOME设置为C:\Program Files\Java\JRE7（更新79)，路径指向JDK 1.7_51/bin。 为什么java版本没有指向java 7 79更新？它指向Java7更新51。理想情况下，它应该指向JRE更新79。

在的下载站点上，它说你可以克隆它来更新它。我下载它是为了安装它，但我开始真正进入并希望从现在开始每次更新它时都克隆它。我想我找到了我们需要克隆它的地方，经过了大量的搜索和比平时更少的文档。如果我是对的，它就在目录中，就在我的眼皮底下！ 我是不是没有找到难以捉摸的文件夹，还是团队直到最新版本发布后才让您直接克隆它？例如，我知道VirtualBox就是这样做的。 我知道这有点重复这个问题，但我尝试了它
