everything works perfect if i give a pid,

but what i want is , automate the process. so it should be i will start the application in emulator , but internally it should get the pid of application and give it to strace and start logging

make it sh.

Replace the app with an executable sh script that does a strace of every call, logging to a separate file with date time pid to be unique.

To be executable, a script must have the execution permission bit set for the intended audience, it must have a #!full_path_to_interpreter_is_sh as the first line (optionally with one argument; for awk and sed you need -f), and off you go. It's in the execvp() man page.
