Android Question Intent.ACTION_TIME_TICK

Why? Use a timer instead.

That's what I did.
But my brother who is a much better programmer than me (with a degree, experience, etc.)
told me that if I worked for him and did it he would fire me ?,
because the application resources should not be used if the operating system can give it to me.
So I wanted to learn how to do it.

There is no advantage for using this intent. It will only make things more complicated, not cross platform and with less control for you.
