Android: Enabled services

Description

Similar to issue #30864 and heavily intertwined with #30863, it is sometimes useful to query what accessibility services a user has currently enabled. This would allow your to tailor your app's UI to the specific service. For example, if a user has the "Talkback" screen reader service enabled, you probably don't want videos to auto-play, as the audio would be interruptive to the screen readers announcements, and if auto-played without audio the videos would be playing and taking bandwidth without the user likely realizing this was happening.

Right now, there is a method in the AccessibilityInfo API to detect talkback specifically (isScreenReaderEnabled), but there is not a general purpose method to get a list of all enabled services.

React Native version:

v0.63

Expected Behavior

The AccessibilityInfo API should have some general purpose method to get a list of all enabled services.

Android Details

This functionality is available in the AccessibilityManager class via the getEnabledAccessibilityServiceList method.
https://developer.android.com/reference/android/view/accessibility/AccessibilityManager#getEnabledAccessibilityServiceList(int)

Commencez par l’API React Native AccessibilityInfo et la méthode Android AccessibilityManager.getEnabledAccessibilityServiceList liées dans l’issue. Déterminez comment les services activés doivent être exposés via l’API, puis vérifiez que les appelants peuvent récupérer la liste complète et que le comportement est cohérent avec les issues d’accessibilité associés.
