我对
Android中“API平台”和“系统映像”的概念感到困惑.他们之间有什么区别？ 最佳答案 Android开发者网站说

The Android system images available through the Android SDK Manager contain code for the Android Linux kernel, the native libraries, the Dalvik VM, and the various Android packages (such as the Android framework and preinstalled applications). The emulator provides dynamic binary translation of device machine code to the OS and processor architecture of your development machine.

The Android platform provides a framework API that applications can use to interact with the underlying Android system. The framework API consists of:

  • A core set of packages and classes

  • A set of XML elements and attributes for declaring a manifest file

  • A set of XML elements and attributes for declaring and accessing resources

  • A set of Intents

  • A set of permissions that applications can request, as well as permission enforcements included in the system
    Each successive version of the Android platform can include updates to the Android application framework API that it delivers.
