Several icons appear when running the application on a real Android Studio device, how to solve this situation?

Question

Java

I am making a small android application. In this project, there are three Activities and each of them is filled, and when this application is launched through a real device, three application icons appear on the phone and each of the bottom is responsible for one Activity. How can these situations be solved so that when the device starts up there is only one icon ? this trouble can grow into a big problem, because I plan to add even more Activities

Intent.Main in your manifest several times. Leave it only at the main one.
