Re: Help with oprofile on android - now its about getting callgraph

Hi,
I finally manged to get oprofile to work on android. I had to use a
cortex_a9 device for this. (earlier, I was using arm_krait and it is not
supported out of the box).

I still am not able to get a callgraph though. In the stats I get
"backtrace_aborted".  When I do a opreport I only get "1 level" details.

I'd really really appreciate it if someone could let me know if I've missed
something

Regards,
Kashyap
