Android window fullscreen with no action bar

Question

I've made my app fullscreen with no title by writing following code

<item name="android:windowNoTitle">true</item>
<item name="android:windowFullscreen">true</item>

But I can open action bar and notifications bar as we usually do from top. Is there any way to never show top action bar.

Fullscreen App:

Visible status bar:

As soon as I touch and slide down from top mobile status bar becomes visible. How to stop that ?

Updates:

AndroidManifest.xml

No. Not a duplicate. I've updated my question with some screenshots to be more specific. TIA — Zain SMJ, Sep 03 '18 at 07:24

Use this code inside the style.xml

<style name="AppTheme" parent="Theme.AppCompat.NoActionBar">
</style>

First, make these changes in the themes.xml file as shown below and then, in AndroidManifest.xml file add "android:theme="@style/FullScreen" this line in activity section.

<resources xmlns:tools="http://schemas.android.com/tools">
                
<style name="Theme._your_app_name" parent="Theme.MaterialComponents.DayNight.NoActionBar">
                    
<item name="colorPrimary">@color/purple_500</item>
<item name="colorPrimaryVariant">@color/purple_700</item>
<item name="colorOnPrimary">@color/white</item>
        
<item name="colorSecondary">@color/teal_200</item>
<item name="colorSecondaryVariant">@color/teal_700</item>
<item name="colorOnSecondary">@color/black</item>
                           
<item name="android:statusBarColor" tools:targetApi="l">?attr/colorPrimaryVariant</item>
                    
</style>

<style name="FullScreen" parent="Theme._your_app_name">
<item name="windowNoTitle">true</item>
<item name="android:windowFullscreen">true</item>

</style>
</resources>

Don't forget to add "android:theme="@style/FullScreen" line in AndroidManifest.xml file under activity section.

Try this!

   @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

            this.requestWindowFeature(Window.FEATURE_NO_TITLE);
            this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
            setContentView(R.layout.activity_main);
    }

in style.xml:

<style name="AppTheme" parent="Theme.AppCompat.DayNight.NoActionBar">
</style>

in manifest application tag:

android:theme="@style/AppTheme"
