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)

Inizia con l’API React Native AccessibilityInfo e il metodo Android AccessibilityManager.getEnabledAccessibilityServiceList collegati nell’issue. Determina come i servizi abilitati dovrebbero essere esposti tramite l’API, quindi verifica che i chiamanti possano recuperare l’elenco completo e che il comportamento sia coerente con le issue di accessibilità correlate.
