The line with error is:

navigationLeft.inflateMenu(R.menu.navigation_left_3)

And the content is:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">

    <item
        android:id="@+id/tab_home_left"
        android:icon="@drawable/ic_tab_home"
        android:title="@string/title_featured" />

    <item
        android:id="@+id/tab_my_products_left"
        android:icon="@drawable/ic_tab_my_products"
        android:title="@string/title_my_products" />

</menu>

I revert it to 1.2.1 to make it work for now.

Our friend here found the problem.

We have created a new file “res/layout/design_bottom_navigation_item.xml” to replace the original and add our accessibility text.

But it has 3 years and our file don’t have the ID field that is recently added android:id="@+id/labelGroup" causing the crash.

We only need add this ID on BaseLineLayout element and it was fixed.

Thanks.

@hemalHD what is the version you are using for com.google.android.material:material in app’ build:gradle and in any of module or dependency? Can you check in dependency graph if 1.2.1 is being used.
