Android TalkBack and fragment stack

Question

For an application that I work on, I need to implement accessibility. Everything works fine except for one screen where I have to fragments added to my activity. Basically,

Answer 1

Adding

view.setImportantForAccessibility(View.IMPORTANT_FOR_ACCESSIBILITY_YES);`
view.performAccessibilityAction(AccessibilityNodeInfo.ACTION_ACCESSIBILITY_FOCUS, null);

inside onResume

and adding

view.setImportantForAccessibility(View.IMPORTANT_FOR_ACCESSIBILITY_NO_HIDE_DESCENDANTS);

inside onPause works for me.
