'Android accessibility identify heading

I have the latest version of Talkback and its announcing "My Top level Text Heading". Android native behaviour is adding "Heading" for my top level elements. I could not find a way to switch ON/OFF heading announcement. Is there an API to control its behaviour. In the previous version of Talkback versions it was not announcing "Heading" by itself.

Solution 1:^[1]

You can enable or disable the "heading" accessibility property of any View on API 19+:

ViewCompat.setAccessibilityDelegate(headingView, new AccessibilityDelegateCompat() {
  @Override
  public void onInitializeAccessibilityNodeInfo(View host, AccessibilityNodeInfoCompat info) {
    super.onInitializeAccessibilityNodeInfo(host, info);
    info.setHeading(true); // false to mark a view as not a heading
  }
});

If you have minSdk 28, you can simply set this directly in your XML:

android:accessibilityHeading="false"

add a simple method on API 19+:

ViewCompat.setAccessibilityHeading(headingView, false);

If you're only supporting API level 23 and above, you can simply do the following.

textView.setAccessibilityDelegate(new View.AccessibilityDelegate() {
  @Override
  public void onInitializeAccessibilityNodeInfo(View host, AccessibilityNodeInfo info) {
    super.onInitializeAccessibilityNodeInfo(host, info);
    //blanked to prevent talkback from announcing class/type
    info.setClassName("");
  }
});

I solved this by passing heading as false in

AccessibilityNodeInfoCompat.CollectionItemInfoCompat.obtain method.

        // set the heading attribute to false so that heading is not announced in label  

info.setCollectionItemInfo(
    AccessibilityNodeInfoCompat.CollectionItemInfoCompat.obtain(glp.getSpanIndex(),
 glp.getSpanSize(), spanGroupIndex, 1, false, false));

public static CollectionItemInfoCompat obtain(int rowIndex, 
int rowSpan, int columnIndex, int columnSpan,
boolean heading, boolean selected)
