一、Android是开源的.Android allows you to access core mobile device functionality through standard API calls.
二、Android不单纯只是操作系统. Linux Kernel:Android relies on Linux version 2.6 for core system services such as security, memory management, process management, network stack, and driver model. The kernel also acts as an abstraction layer between the hardware and the rest of the software stack. Android Runtime:The Dalvik VM,有了Java虚拟机,大部分Java核心类库都已经可以直接运行. Libraries:Android includes a set of C/C++ libraries used by various components of the Android system. These capabilities are exposed to developers through the Android application framework. Some of the core libraries are listed below:System C library ,Media Libraries ,Surface Manager ,LibWebCore ,SGL , ,3D libraries ,FreeType ,SQLite.
