Answer 1

adb shell ps -A is listing all processes in android-8.0-O release.

I think Google has upgraded ps binary in this release.

What's the output your getting – Jeffry

I am getting null string when i am reading after executing process – Neilneila

Got your code from another company question, let me try and update – Jeffry

Hi @Jeffry I am only getting list of process by system not getting any root process so any solution for that ? I am applying this command progrmatically and I am getting process which are aquired by same user not from root or system. Any solution for this ? – Jink

As long as process is running, it will be listed irrespective of user. Are you sure your processes is still running? – Jeffry

Yes @Jeffry process is running. I am sure on that because I am running that system process manually. When I am running the same command in windows it gives me process data of system, root and user but when I am progrmatically firing same command in device it gives me data of user only. This is how I am running the commandd in android. Process p = Runtime.getRuntime().exec("ps"); – Jink

@Jeffry when I run it via machine terminal, it lists all processes but, when I run it in the Android app code, it only lists the app process and ps process! – Risinger

Answer 2

Answer is: ps -A

But, there are so many new options in ps. Try running ps --help

generic_x86:/ $ ps --help
usage: ps [-AadefLlnwZ] [-gG GROUP,] [-k FIELD,] [-o FIELD,] [-p PID,] [-t TTY,] [-uU USER,]

List processes.

Which processes to show (selections may be comma separated lists):

-A  All processes

-a  Processes with terminals that aren't session leaders

-d  All processes that aren't session leaders

-e  Same as -A

-g  Belonging to GROUPs

-G  Belonging to real GROUPs (before sgid)

-p  PIDs (--pid)

-P  Parent PIDs (--ppid)

-s  In session IDs

-t  Attached to selected TTYs

-T  Show threads

-u  Owned by USERs

-U  Owned by real USERs (before suid)

Output modifiers:

-k  Sort FIELDs in +increasing or -decreasting order (--sort)

-M  Measure field widths (expanding as necessary)

-n  Show numeric USER and GROUP

-w  Wide output (don't truncate fields)

Which FIELDs to show. (Default = -o PID,TTY,TIME,CMD)

-f  Full listing (-o USER:12=UID,PID,PPID,C,STIME,TTY,TIME,ARGS=CMD)

-l  Long listing (-o F,S,UID,PID,PPID,C,PRI,NI,ADDR,SZ,WCHAN,TTY,TIME,CMD)

-o  Output FIELDs instead of defaults, each with optional :size and =title

-O  Add FIELDS to defaults

-Z  Include LABEL
