How Intent method knows that it needs to change Activities when a user pushes the button?

How Intent method knows that it needs to change Activities when a user pushes the button? Because we did not initialize intent for Button? We just initialized that it needs to switch from MainActivity to StoryActivity?

Hello,

When you created the Intent object, I imagine you did so within the "onClickListener" of the button. This means that the button is waiting for you to click on it. Once you click on the button, it runs the code within the onClick method... which in your case is create an Intent to start a new activity, and then start the new activity.

Hello,

At the end of the video, the function startActivity(intent); is called which tells Android to start the new activity.
