Android root poweroff

Question

On my android app for root user, I perform a shutdown with

su reboot -p

It works ok, but I noticed that the phone is shutdown almost instantly (as opposed from showing the shutdown animation, and probably doing other stuff).

Is this the correct way to shutdown an android phone programmatically? Are there some critical code that requires to be executed before shutdown?

If your app is rooted, then run the following as root:

am start -a android.intent.action.ACTION_REQUEST_SHUTDOWN
