How to determine and set the minimum android version for an application?

Question

Android

Hello, I'm a web developer and have never done mobile development before. I made an application on cordova for android (I think this is not important, it seems to be no different from webview in native applications).
On some phones, the application is displayed very crookedly (phones are properly old). How to deal with it? How to detect such phones and maybe just disable installation on them? The problem, apparently, is not in the android version, but in the phone's browser?
In the application settings, I saw only device restrictions on the availability of memory / processor power.
Tell me please.

Answer 1

before some version of android, the webview system component was part of, ahem, the system!
for this reason, it received updates very infrequently.
but then a turning point came and he was taken to the market and everything began to sparkle with new colors.
did it affect older versions of android? I think no.
I can’t say anything specifically about Cordova, alas.
