Android Auto text sizing not working

Question

I am trying to make my application responsive by putting the auto resize text option but it seems that its not working. I am using the android auto size tag :

 <TextView
        android:id="@+id/textView11"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingLeft="60px"
        android:paddingTop="160px"
        android:text="@string/greetings1"
        android:textColor="@color/black"
        app:autoSizeTextType="uniform"
        app:autoSizeMinTextSize="5sp"
        app:autoSizeMaxTextSize="100sp"
        app:autoSizeStepGranularity="2sp"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        tools:ignore="MissingPrefix" />

When I run it on my phone it does not resize at all. please help

From Autosizing TextViews

If you set autosizing in an XML file, it is not recommended to use the value "wrap_content" for the layout_width or layout_height attributes of a TextView. It may produce unexpected results.

You should bound Height

android:layout_width="match_parent"
android:layout_height="50dp"
