I have a Tablayout fragment with bottomnavigationview which contains three fragments. Each fragment has a recyclerview and a spinner in it. My tablayout fragment xml file is as follows
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

However I cannot see any circular references in both layouts. Note that the same layout is working on Nougat and above. I cannot seem to understand what is causing this. This is my java class where i update the spinner and recyclerview

I am stuck on this. Any help will be greatly appreciated. Thank you.
EDIT1
Removed all relative layouts from screen. Still giving me circular dependency error in relative layout. Now this is pissing me off.
EDIT2
On further digging out, I found out that it is crashing in builtin class Recyclerview.java inside if condition at this line child.measure(widthSpec, heightSpec);. Don't know still what is causing this.
public void measureChildWithMargins(View child, int widthUsed, int heightUsed) {
final LayoutParams lp = (LayoutParams) child.getLayoutParams();
final Rect insets = mRecyclerView.getItemDecorInsetsForChild(child);
widthUsed += insets.left + insets.right;
heightUsed += insets.top + insets.bottom;
final int widthSpec = getChildMeasureSpec(getWidth(), getWidthMode(),
getPaddingLeft() + getPaddingRight()
+ lp.leftMargin + lp.rightMargin + widthUsed, lp.width,
canScrollHorizontally());
final int heightSpec = getChildMeasureSpec(getHeight(), getHeightMode(),
getPaddingTop() + getPaddingBottom()
+ lp.topMargin + lp.bottomMargin + heightUsed, lp.height,
canScrollVertically());
if (shouldMeasureChild(child, widthSpec, heightSpec, lp)) {
child.measure(widthSpec, heightSpec);
}
}
