how to run shell commands in ndk

[neeraja]

Hi,
main()
{
int i = execv("su"); ;
}

returns -1, file not found.
I want to run my daemon from android ndk.

try to specify the path to the executable (e.g. /system/bin/su). Are you sure there is an "su" executable on your system anyway.

Keep in mind that forking and execing from application processes is not supported by the system. What this means is that

the system might decide to abruptly kill any of such processes if it finds one. The feature might even be removed in the future

(e.g. would fail with a permission error).

Also, no shell commands are part of the SDK/NDK -- you can't count on them existing across platforms or devices or behaving the same way.
