When setting Full screen with navigation bar and status bar fitsystemwindows is ignored

Question

I want the background of screen(login screen background is just a gradient) to be shown behind transparent toolbar and transparent navigationbar but the paddings needs to be added manually. Currently I add padding to toolbar 20dp to make it look like it has too but the soulution should be to use fitsystemwindows on container and on toolbar, but it doesn't work, because we set flags programatically and i think it overrides them. Does anybody have a solution. I tried with styles and it works but the navigation bar isn't completly transparent it has transparent black border the only thing that i found that worked was if i set flags programatically. Any ideas?

Actvity:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
    }

XML

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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:background="@drawable/background_gradient_blue_to_dark"
    android:orientation="vertical"
    android:fitsSystemWindows="true">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/transparent"
        android:fitsSystemWindows="true"
        android:minHeight="?attr/actionBarSize"
        android:paddingTop="20dp" />  <!-- Current solution for padding because fitsystemwindows doesn't work-->
</LinearLayout>

EDIT Added screenshots This is how it is without padding:

And with padding.

Try this

Layout file

<?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:background="@drawable/nilesh"
    android:fitsSystemWindows="true"
    android:orientation="vertical">


    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:minHeight="?attr/actionBarSize" />


</android.support.design.widget.CoordinatorLayout>
