How is the process of testing an Android application with experienced developers?

Question

Android

Interested not in hypothetical options, but in real cases, who is currently testing their developments for Android?
I will give an example from web development. In the days of old browsers, like IE6, you had to check the layout in several versions of IE and in different browsers in general.
Now layout for browsers has been greatly simplified and you can layout for any modern browser without checking the layout in the others, because. it is enough to know only a small number of layout nuances for old browsers (ie11). The same goes for the mobile version.
How bad (good?) is it on android now? Is it necessary to have a whole zoo of diverse devices for development, or is an emulator enough, a device master for the final check and knowledge of the nuances? Or maybe everyone uses some kind of automated testing service on real devices?

Answer 1

I'm not a professional android developer, but I've experienced that most devices do not work like an emulator. For a video player, we had about five devices at work, which was clearly not enough. There was a cool article on the hub on how to cover most of the users' devices with a small number of devices, although it is now outdated. Well, there are also services that provide access to real devices, although they are not free.
