Android: aria-busy, aria-checked="mixed" and aria-valuetext replace the element's name in TalkBack #59856

Description

On Android, busy, checked: 'mixed' and accessibilityValue.text (and their aria-* props) are written into the view's contentDescription (BaseViewManager.java#L466-L498). Without an accessibilityLabel the description is only these words, and TalkBack reads it instead of the element's text:

• <Pressable aria-busy><Text>Results</Text></Pressable> is read as "busy".
• <Pressable role="checkbox" aria-checked="mixed"><Text>Select all</Text></Pressable> is read as "mixed", with no name.
• <View accessible role="slider" aria-valuetext="3 of 5" ...><Text>Rating</Text></View> is read as "3 of 5".
• <Text aria-busy>Saving</Text> is read as "busy".

iOS keeps the name and reads these words as the value. On Android they belong in stateDescription. I'll send a fix once #59009 and #58825, which add stateDescription for checked, are settled.

This is the bug #59816 mentions for aria-busy and aria-checked="mixed".

Steps to reproduce

1. Run the reproducer from ReproducerApp: yarn install, then yarn android.
2. Turn on TalkBack and go through the sections. In each one, the second element is the same without the prop.

Expected: the name is read together with the state or value, as on iOS.

Actual: only "busy", "mixed" or the value text is read. The second element is read by its name.
