bugreport：启动dumpstatus服务，并通过socket连接，读取信息，并保持到stdout管道中 frameworks/native/cmds/dumpstatus dumpstatus：android的相关信息,内核，进程，相关信息的主要实现地方。我们就 frameworks/native/cmds/dumpysy dumpsys: 获取android服务进程的各个信息,比如dumpsys media.audio_policy 等 dumpstate主要获取信息： 1，基本信息，如版本信息，内存基本信息，cpu基本信息，硬件信息等 2，系统log 3，网络信息，路由信息，网络撇之信息 4，panic信息 5，锁的使用信息 6，进程信息 7，binder信息 8，应用程序安装信息 9，磁盘使用情况 10，所有activity,services 信息 11，properties信息等通过费纳西 dumpstate工具代码，我们能有效的了解在android中过去各种信息，有针对性的对自己需要的信息进行获取。学到了linux的上层如果对系统信息进行管理与统计的！如要获取信息渠道： 1,cat proc各个节点获取想要信息 2，property_get各个属性的信息 3，run_commend去运行系统命令，获取需要的信息。主要是这样的方法 4，dumpsys命令下面附上该函数的实现文件： frameworks/native/cmds/dumpstate/dumpstate.c 文件： [cpp] //主要处理函数与注释 static void dumpstate() { time_t now = time(NULL);//当前时间 char build[PROPERTY_VALUE_MAX], fingerprint[PROPERTY_VALUE_MAX];
