Android appcompat full screen and hide status bar

styles.xml

<resources>

    <style name="AppTheme" parent="@style/Theme.AppCompat.Light">
        <item name="android:windowNoTitle">true</item>
        <item name="windowActionBar">false</item>
        <item name="android:windowFullscreen">true</item>
        <item name="android:windowContentOverlay">@null</item>
    </style>

</resources>

"android:windowNoTitle" doesn't support AppCompat Theme. Use below instead

<style name="AppTheme" parent="@style/Theme.AppCompat.Light">
     <item name="windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowContentOverlay">@null</item>
</style>
