I’m trying to test Strace tool in Android Real device but I can’t get

  • 0

I’m trying to test Strace tool in Android Real device but I can’t get any information from it.
I was trying the following command but the device still tell me “permission denied”.

 '$' adb shell su strace -p <PID_number>

I tried to split the commands and make it in two times in this way and it works

 '$' adb shell su
 '#' strace -p <PID_number>

I tried to put the previous code in this way, to make it secuentially but still is not working:

 '$' adb shell su  && strace -p <PID_number>

What I’m doing wrong? Thanks in advance

    Hey guys finally I found the answer and I want to share it with you 🙂

    As you can see in the previous picture I was using shell:shell in strace instead of root:shell so I changed using the following command:

    '#' chown root strace

    After that I give permission to execute with this one:

    '#' chmod 4777 strace

    So now, I have strace in this way and I don’t see anymore “”ptrace attach failed: Operation not permitted” message

    -rwsrwxrwx root shell 134508 2011-03-1 16:41 strace

    Thank you to everybody helping me finding the solution 😉
