Android: Progress Bar values not announced

[amarlette]

Description

In the component, when using a screen reader it does not announce current value on focus. Without this, the progress bars are not usable.

React Native version:

v0.63

Expected Behavior

The current value of the progress bar should be announced on focus.

While not standard Android system behavior, progress bars could be improved by adding an option to automatically announce their progress as it increments.

Android Details

Accessibility for Progress bars on Android rely heavily on the AccessibilityNodeInfo's RangeInfo class. This class defines a min, max, and current value, and should be attached to the AccessibilityNodeInfo for any progress bar component.

Currently, this all works if using the accessibilityValue prop, but the built in class does not do this automatically.

@kacieb , @nadiia , @lunaleaps , this issue was with the component, which is not included in the docs on reactnative.dev, so my guess is it's either deprecated, or not an officially supported component. That being said, it is included in the repo, so we should probably fix it, or delete it since it doesn't really work.

Yea it looks deprecated: https://reactnative.dev/docs/progressbarandroid. This is not worth looking into since we're recommending users to use a community package instead -- should we close the issue @amarlette?

@lunaleaps ProgressBarAndroid component is deprecated since 0.63 (f295d7f) release.

You might want to report the issue in the extracted package from core (https://github.com/react-native-progress-view/progress-bar-android). It was a part of RNC, but lately the policy have changed and many packages have been moved to their own organizations.

This is also the reason why we lately switch from recommending single package to RN Directory links:

• update deprecation notes to point to the RN Directory instead of single package react-native-website#2470

@blavalla @cortinico should be closed in favor of react-native-progress-view/progress-bar-android#61
