Simulate a click on touch-screen's phones

How can I do that using arduino?

I want to code something like:

click;
wait(100);
click;
wait(200);

Is there a way to do that? It's for an academic project like clicking every X seconds on a screen using a APK that I designed to count every touch-click.

Thanks in advance.

Is there an actual phone? Then use a servo to press on the screen.

If it's a simulation of a phone on a PC, then I don't see that an Arduino is necessary.

If it's android, use adb, and simulate input events.

Yes. There is... I've installed on my personnal phone and now I need to make the "auto clicker" to test my software.

Yes.... but If the test works, I'd probably use on another software.. And its 99% sure that the chosen software is a game and the people who are going to watch it they need to "see" the clicks.
