Android start stop 重启framework_android 重启framework

使用stop start命令来重启framework，我们来看下其代码

是在system/core/toolbox下面,原理很简单就是利用ctl属性来控制进程。

start.c

stop.c

#include <stdio.h>  
#include <string.h>  
  
#include <cutils/properties.h>  
  
int stop_main(int argc, char *argv[])  
{  
    if(argc > 1) {  
        property_set("ctl.stop", argv[1]);  
    } else{  
        /* defaults to stopping the common services */  
        property_set("ctl.stop", "zygote_secondary");  
        property_set("ctl.stop", "zygote");  
        property_set("ctl.stop", "surfaceflinger");  
        property_set("ctl.stop", "netd");  
    }  
  
    return 0;  
}
