How avoid java.lang.NullPointerException

I'm using androidx.appcompat.widget.SearchView as I noticed when I set this app:iconifiedByDefault="false" property in my searchView app throws java.lang.NullPointerException: Attempt to invoke virtual method 'int android.graphics.drawable.Drawable.getIntrinsicWidth()' on a null object reference is there a way to avoid throwing this exception?

<androidx.constraintlayout.widget.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:padding="15dp"
        tools:context=".navigation.home.search.GameSearchFragment">

        <com.google.android.material.appbar.MaterialToolbar
            android:id="@+id/searchToolbar"
            style="@style/TextAppearance.AppCompat.Widget.ActionBar.Title"
            android:layout_width="match_parent"
            android:layout_height="50dp"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintHorizontal_bias="0.0"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent"
            android:contentInsetStart="0dp"
            app:contentInsetStartWithNavigation="0dp"
            app:contentInsetStart="0dp">

            <androidx.appcompat.widget.SearchView
                android:id="@+id/search"
                android:layout_width="match_parent"
                android:layout_height="30dp"
                android:background="@color/primaryColor"
                app:defaultQueryHint="Search Games"
                app:iconifiedByDefault="false"
                android:theme="@style/SearchStyle"
                app:searchIcon="@null"
                app:queryBackground="@android:color/transparent">

            </androidx.appcompat.widget.SearchView>

        </com.google.android.material.appbar.MaterialToolbar>

        <View
            android:layout_width="match_parent"
            android:layout_height="1dp"
            android:background="@color/searchViewBorder"
            app:layout_constraintEnd_toEndOf="@+id/searchToolbar"
            app:layout_constraintStart_toStartOf="@+id/searchToolbar"
            app:layout_constraintTop_toBottomOf="@+id/searchToolbar">

        </View>


    </androidx.constraintlayout.widget.ConstraintLayout>

I ran into the same issue and it was because I was using an EditText but the style was inheriting from TextView, weirdly the EditText worked until the user entered some text in it and then when the field received focus it would crash with java.lang.NullPointerException: Attempt to invoke virtual method 'int android.graphics.drawable.Drawable.getIntrinsicWidth()' on a null object reference.

Hope this helps someone...

Before (caused crash)

    <style name="InputMethodEditText" parent="@android:style/Widget.TextView">

After (no crash)

    <style name="InputMethodEditText" parent="@android:style/Widget.EditText">

So I fixed it, The problem was that I used theme style in search View and style was inherited from EditTextView I changed it to SearchView And problem was fixed

Before - <style name="SearchStyle" parent="Widget.AppCompat.EditText"> After - <style name="SearchStyle" parent="Widget.AppCompat.SearchView">

Try to use android:iconifiedByDefault="false" not app:iconifiedByDefault. If it does not work, share your java or Kotlin code please
