remove white space from the navigation bar android

I am trying to enable full screen mode but the problem is that there is permanent white space at the navigation bar which does not hide at all. I need to remove that white space. Here is the implementation
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"

app:resize_mode="fit"
app:player_layout_id="#layout/exo_simple_player_view"
app:use_controller="true"
/>
</RelativeLayout>
This is the styles.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="AppTheme" parent="Theme.MaterialComponents.Light.DarkActionBar">
<item name="colorPrimary">#color/purple_700</item>

<item name="windowActionModeOverlay">true</item>
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="android:navigationBarColor">#android:color/transparent</item>
</style>
Any suggestion would be helpful to me. Thanks

Change the parent theme from
Theme.MaterialComponents.Light.DarkActionBar
to
Theme.MaterialComponents.Light.NoActionBar
OR
If you want full screen only for this activity then do as follow in your AndroidManifest.xml file:
<activity
android:name=".YourActivityName"
android:theme="#style/AppTheme.NoActionBar" />
And add below style in your styles.xml
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>

Theme.MaterialComponents.Light.DarkActionBar
to
Theme.MaterialComponents.Light.NoActionBar

CoordinatorLayout + AppBarLayout + Transparent Status Bar

My Scenario
I have an Activity(min SDK 19) with Coordinator and AppBar with Image and Scroll Behaviors, everything works fine except my status bar is not transparent nor translucent. Below is my
<style name="AppTheme.Collapsing">
<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowTranslucentNavigation">true</item>
</style>
And I set that style to that Activity in manifest. Below is my xml layout.
These are images what I really want and what I got.
Image 1. I got like that, no transparent status bar.
Image 2. I want like that, with transparent status bar.
Image 3. Result after scroll, this is ok.
`<androidx.coordinatorlayout.widget.CoordinatorLayout

`

You can try this style file
styles.xml;
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar"/>
<style name="AppTheme.NoActionBar">
<item name="android:textColorSecondary">#color/white</item>
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="android:windowBackground">#color/colorPrimaryDark</item>
<item name="android:windowDisablePreview">true</item>
<item name="colorPrimary">#android:color/transparent</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="drawerArrowStyle">#style/DrawerArrowStyle</item>
<item name="colorPrimaryDark">#android:color/transparent</item>
</style>
also you need to create style for API Level 21
styles.xml for v21;
<style name="AppTheme.NoActionBar">
<item name="android:windowBackground">#color/colorPrimary</item>
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="android:windowDisablePreview">true</item>
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">#android:color/transparent</item>
<item name="colorPrimary">#android:color/transparent</item>
<item name="colorPrimaryDark">#android:color/transparent</item>
<item name="android:colorAccent">#color/colorAccent</item>
<item name="android:textColorSecondary">#color/white</item>
</style>
then in your AndroidManifest.xml file you need to specify your style for your application
AndroidManifest.xml
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:networkSecurityConfig="#xml/network_security_config"
android:roundIcon="#mipmap/ic_launcher"
android:supportsRtl="true"
android:theme="#style/AppTheme.NoActionBar"
android:usesCleartextTraffic="true"
tools:ignore="GoogleAppIndexingWarning">
...
</application>
Another issue that i encounter when i try to make layout with transparent status.
I needed to put xml layout content inside DrawerLayout to make status bar transparent.

Change all android:fitsSystemWindows attribute from "true" to "false", this may help you get a translucent status bar,
but after you do this, your collapsingbarlayout is collapsed and the title in your toolbar may be shown in the status bar,
then you can try add android:layout_marginTop attribute in your toolbar and set its value to "20dp".

Android: How to remove line between Toolbar and Statusbar

I am interested in having a uniform coloured toolbar and status bar. If I provide colorPrimary and colorPrimaryDark as the same colour this should be possible. I am getting the desired result using ActionBar but not with Toolbar. I will also be creating a navigation view so i need the status bar as transparent.
Code : Styles-v21
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">#android:color/transparent</item>
</style>
Code : Styles
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimary</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar"/>
<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light"/>
</resources>
Steps to reproduce :
Create a new project in android studio with Navigation Drawer Activity
Set primary and primaryDark as same colours
Run on device or emulator

The only solution I could come up with was to remove android:fitsSystemWindows="True" from Coordinator Layout
edit : Another solution is to wrap coordinator layout in another coordinator layout.
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay"
app:layout_scrollFlags="scroll|enterAlways">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay"/>
</android.support.design.widget.AppBarLayout>
<include
layout="#layout/content_main"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
</android.support.design.widget.CoordinatorLayout>
</android.support.design.widget.CoordinatorLayout>
Before
After

This shadow you are seeing is window content overlay, you could remove it:
Please add this line to your theme specification:
<item name="android:windowContentOverlay">#null</item>

Toolbar is not visible on Android 4.X devices

I just updated android.support:appcompat lib to 22.1.1.
Toolbar is visible on a Lollipop device but not on a 4.X device.
I have even tried extending AppCompatActivity, but still no luck. If anything else is required please let me know.
Here is my project styles and base activity xml file.
styles.xml
<style name="AppTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#color/primary</item>
<item name="colorPrimaryDark">#color/primarydark</item>
<item name="colorAccent">#color/primary</item>
<item name="colorControlHighlight">#color/primary</item>
<item name="drawerArrowStyle">#style/DrawerArrowStyle</item>
<item name="windowActionModeOverlay">true</item>
<item name="windowActionBarOverlay">true</item>
<item name="android:windowActionBarOverlay">true</item>
<item name="android:windowBackground">#color/activity_bg</item>
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
activity_base.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/fulllayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.Toolbar
android:minHeight="?attr/actionBarSize"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/toolbar"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
android:background="#color/primary">
</android.support.v7.widget.Toolbar>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/container">
</FrameLayout>
</RelativeLayout>
Update :
Issue is with layout inflated in container part. it is overlapping toolbar so i have removed all views and it worked.
Thanks all...

Why is using a material AppCompat theme causing full screen?

I'm trying to switch over an app to use Theme.Material, I have a toolbar setup with fitsSystemWindows set to true yet my activity extends below the navigation bars!!
Here's my theme
<style name="FlowTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#color/primary</item>
<item name="colorPrimaryDark">#color/primaryDark</item>
<item name="colorAccent">#color/accent</item>
<item name="android:windowFullscreen">false</item>
<item name="android:fitsSystemWindows">true</item>
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="cpvColor">#color/accent</item>
<item name="cpvStrokeWidth">3dp</item>
<item name="cpvCircleAnimDuration">1400</item>
<item name="cpvSweepAnimDuration">950</item>
</style>
Nothing is triggerend in my activity to flag fullscreen
What's going on? how do I fix this so that it's not fullscreen?
Edit: Here's my main activity XML
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/bg_color"
android:orientation="vertical">
<include
android:id="#+id/toolbar_actionbar"
layout="#layout/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".ActMain"
tools:ignore="MergeRootFrame"
android:layout_below="#+id/toolbar_actionbar" />
</LinearLayout>
<fragment
android:id="#+id/fragment_drawer"
android:name="com.metalab.flow.ui.fragments.FrNavigationDrawer"
android:layout_width="260dp"
android:layout_height="match_parent"
android:layout_gravity="start"
app:layout="#layout/fr_navigation_drawer" />

this is the reason
Theme.AppCompat.Light.NoActionBar // i show no actionbar..
put this in your activity xml layout, if its linearLayout let it be the first child, if its RelativeLayout let it be on top and all children should align to it..
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
app:theme="#style/FlowTheme" />
style
<style name="FlowTheme" parent="Theme.AppCompat.Light">
<item name="colorPrimary">#color/primary</item>
<item name="colorPrimaryDark">#color/primaryDark</item>
<item name="colorAccent">#color/accent</item>
<item name="android:windowFullscreen">false</item>
<item name="android:fitsSystemWindows">true</item>
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="cpvColor">#color/accent</item>
<item name="cpvStrokeWidth">3dp</item>
<item name="cpvCircleAnimDuration">1400</item>
<item name="cpvSweepAnimDuration">950</item>
</style>

As it turns out I was using this class, for a core WebView bug fix https://github.com/madebycm/AndroidBug5497Workaround
Removing it's use fixed my issue, however the WebView resize bug lives on...

You are using wrap_content in your toolbar, and if you havent given support to it, then it hasn't content to show. I recomend you that change the height of the toolbar to:
android:layout_height="?attr/actionBarSize"
And you should give support in your java file to show the title and buttons:
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar_actionbar);
setSupportActionBar(toolbar);
EDIT: I read some of other replies, and I add more info because I suppose that you had the toolbar defined in other xml. This is an example of toolbar that you should include:
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:translationZ="4dp"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar" />
