Error inflating class io.github.yavski.fabspeeddial.FabSpeedDial

Hi, Below is the XML:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity"
    >

    <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:padding="16dp">

        <io.github.yavski.fabspeeddial.FabSpeedDial
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="bottom|end"
            app:fabGravity="bottom_end"
            app:fabMenu="@menu/menu_main"
            app:miniFabBackgroundTint="@android:color/white"
            app:miniFabDrawableTint="?attr/colorPrimaryDark"
            app:miniFabTitleTextColor="?attr/colorPrimaryDark" />

    </FrameLayout>

</RelativeLayout>

@prashanthd Sometimes commenting on xml gives bizarre errors. Try deleting the dateFilter row and check if it works.

Look your layout for this namespace xmlns:app=“http://schemas.android.com/apk/res-auto” If not just copy and paste it
