Properties mechanism for Android 2.3.4 (e.g. Ctl.start)

The Android system uses a number of attributes to record system settings and process communication. Properties are globally visible throughout the system. Each process can get/set properties. When the system is initialized, Android assigns a shared memory area to store the properties. This is done by the Init process (see SYSTEM/CORE/INIT/INIT.C): After executing the system boot process, the init daemon becomes a background service for property management and receives administrative requests for attributes from other processes.

SetProp Ctl.start $SERVICE _name #启动某个服务
SetProp ctl.stop $SERVICE _name #停止某个服务
