Android ADB Linux problem

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 ;)

Use:

$ adb shell su -c strace -p <PID>

or set the SETUID bit on strace.

Non-rooted phones won't let you run the su command. Besides, strace is not a default binary in android. In order for this command to work you will need a rooted device and an ARM binary of strace.
