Can't be read / closed with TalkBack

The announcement can't be read via TalkBack. Even worse: it can't be closed via TalkBack too! (it can, but only with the back button and since there is no indication what's going on, a blind person has no idea they should do this). This means that this library basically renders the app unusable for blind people.

The easiest fix would be to simply not show anything when touch navigation is enabled:

fun Context.isTouchExplorationEnabled(): Boolean {
    // can be null during unit tests
    val am = getSystemService(ACCESSIBILITY_SERVICE) as AccessibilityManager?
    return am?.isTouchExplorationEnabled ?: false
}

Actually making it work would be a very nice option. With it, you'd have to set the contentDescription to View and allow closing it by clicking on it when touch exploration is enabled.

it would be amazing if the content of the feature can be read from talkback, I tried right now and it's a frustrating experience, imagine from blind people.

Are there any updates on this issue? I would like to add that the missing content description also generates a warning in Google's pre-launch report that I'm not able to solve.

The issue can be solved in client code by setting an AccessibilityDelegate on the TapTargetView that is returned by TapTargetView.showFor:

    ViewCompat.setAccessibilityDelegate(tapTargetView, object : AccessibilityDelegateCompat() {
        override fun onInitializeAccessibilityNodeInfo(
            host: View,
            info: AccessibilityNodeInfoCompat,
        ) {
            super.onInitializeAccessibilityNodeInfo(host, info)
            info.contentDescription = "$title: $description"
            info.addAction(AccessibilityNodeInfoCompat.ACTION_DISMISS)
            info.isDismissable = true
        }

        override fun performAccessibilityAction(
            host: View,
            action: Int,
            args: Bundle?,
        ) = if (action == AccessibilityNodeInfoCompat.ACTION_DISMISS) {
            tapTargetView.dismiss(false)
            true
        } else super.performAccessibilityAction(host, action, args)
    })

If the maintainers are interested in adding this to the library, I can prepare a MR.
