How to get root rights on android?

Question

Android

Is there a programmatic way to set root on android?
There are applications that you enter, press one button and all the root is installed, well, maybe you need to reboot the phone there? How do they do it?

Is it possible to get root without any TWRP and installing the application through it.
Just download the apk, click the button and you're done.

Answer 1

Android rooting is the "opening" of the operating system and the introduction of functions not provided by the manufacturer.
if we get lucky.
old androids had holes and rooting happened through the application.
now varies from phone to phone.
