How to test an android app on Android Studio?

I downloaded that app yesterday and I choose empty project. It has a hello world screen. When I click run, a windows that looks like a "smart phone" appears and then disappears quickly. I didn't edit the codes or anything. I just want to test the "hello world" app. How can I do this?

I just created the empty one that has "Hello World" text in the middle of the screen. That's it. I didn't edit anything. I'll check the link that you gave me and inform you later. Are there any other software to code android apps other than Android Studio? Thank you,

I think Android Studio is kind of the go-to since it already has all the dependencies and is integrated with the emulator.
