Android Studio – How to remove purple header from the android app

I am strugling with removing this purple header from the android app. Tried following 2 solution, but none of them worked for me.

  1. Change the style -> parent in style.xml

<style name="Theme.MaxCogito" parent="Theme.AppCompat.Light.NoActionBar">

  1. Adding following code to onCreate() (this code actually broke my code) YouTube
requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
getSupportActionBar().hide();

enter image description here

    That "Purple bar" is called as the status bar. If you would like to hide it,

    <application
    ...
    android:theme="@android:style/Theme.Holo.NoActionBar.Fullscreen" >
</application>

    For API_LEVEL < 16

    getWindow().setFlags(
    WindowManager.LayoutParams.FLAG_FULLSCREEN,
    WindowManager.LayoutParams.FLAG_FULLSCREEN
);

    For API_Level >= 16

    getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN);
getActionBar().hide();

    Your code doesn’t works because you API Level is newer than 16 (probably)

    Add the following code inside MainActivity under the onCreate method:

    window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_FULLSCREEN

    This requests the OS to change the visibility of the status bar to be hidden.

    In your onCreate method just add this
    In Kotlin

    override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    // If the Android version is lower than Jellybean, use this call to hide
    // the status bar.
    if (Build.VERSION.SDK_INT < 16) {
        window.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN)
    }
    setContentView(R.layout.activity_main)
}

    In Java

    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // If the Android version is lower than Jellybean, use this call to hide
    // the status bar.
    if (Build.VERSION.SDK_INT < 16) {
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
    }
    setContentView(R.layout.activity_main);
}

    }

    Use that inside the styles of theme you are using.

    <resources xmlns:tools="http://schemas.android.com/tools">
    <!-- Base application theme. -->
    <style name="m_ammar_tentwenty" parent="Theme.MaterialComponents.DayNight.NoActionBar.Bridge">
        <!-- Primary brand color. -->
        <item name="colorPrimary">@color/app_light_gray</item>
        <item name="colorPrimaryVariant">@color/app_white</item>
        <item name="colorOnPrimary">@color/app_white</item>

        <!-- Status bar = responsible for the background color. -->
        <item name="android:statusBarColor" tools:targetApi="l">?attr/colorPrimaryVariant</item>
        <!-- Status bar text colors handle from here -->
        <item name="android:windowLightStatusBar" tools:ignore="NewApi">true</item>

        <!-- Customize your theme here. -->


    </style>
</resources>
