For custom elements to provide a custom role you must use
AccessibilityDelegateCompat
(https://medium.com/android-microsoft/android-accessibility-resolving-common
-talkback-issues-3c45076bcdf6#d51f), but realize doing so you are taking
over providing accessibility information for that element if something for
that element is updated.

Better to user native elements for their specified purpose, when possible.

Android does need better support for roles and states in general IMO.

Also, TalkBack users can turn off roles if they really want to:

If it's a native Android button it will be announced as a button.
If it is a custom element that acts like a button, yes, it needs to be
announced as a button (all interactive elements should have the appropriate
role, that is a WCAG 4.1.2 requirement that applies just as much on mobile
apps as it does to web).
I have a code snippet that assigns a button role to a custom Android
component, but I have to dig it up.
