Android Adb命令(4) - ps 查看进程信息

1. 查看所有进程信息：

adb shell ps -A

则得到：

USER           PID  PPID     VSZ    RSS WCHAN            ADDR S NAME
root             1     0 12510356  5276 ep_poll             0 S init
root             2     0       0      0 kthreadd            0 S [kthreadd]
...
system         603     1 12539680  3468 ep_poll             0 S servicemanager
...
system        1065   879 23323448 443428 ep_poll            0 S system_server
....

可以看出 :

PID 1065 对应的是 system_server进程

PID 603  对应的 servicemanager 进程 (用于Binder 通信)

2. 查看某个进程下的所有线程信息：

adb shell ps -T [PID]

如查看上面 system_server 进程下的所有线程信息：

adb shell ps -T 1065

则得到：

USER           PID   TID  PPID     VSZ    RSS WCHAN            ADDR S CMD
