I have an app That I made in Android Studio. I want to publish the app. How do I know for sure that the app willl work if someone else downloads it?

By testing it on your own phones

It works on my phone, but it does not work on other phones
You can download some android emulators like Bluestacks to test it out.

There could be many reasons why it doesn't work on other phones, screen size, API level too high / depreciated functions , trying to access file/folders that don't exist. You just have to debug it with phones of all kinds.

This isn't even necessary, is it? Android Studio has emulators in itself for you to try the app on different version
