lower level system

Another one of the great things about Android (if you're a geek or a tinkerer) is that you have lower-level access to the system itself.

关于Android的另一个利好的事情之一是你有低级别的权限访问系统本身。

This allows developers to design modular application architectures on top of a lower-level modularity system such as OSGi.

这使得开发者可以在低层次的模块化系统(如osgi)之上设计模块化应用架构。

There are also new classes allowing access to lower-level information about the file system, and even to supply providers (called FileSystem and FileStore) to access any type of file system you wish.

还有新的类，来允许访问文件系统的低级信息，并支持提供者（称为 FileSystem 和 FileStore）访问任何想要访问的文件系统。
