How do I get rid of the elevation in the status bar? If I set in AppbarLayout the app:elevation to 0dp the elevation doesn't appear anymore in status bar but also not below the AppbarLayout.
How do I just get the elevation under the AppbarLayout?
Here's a screenshot of what I mean: puush link, notice the shadow in the status bar :(
Thanks!

Our concern is about shadow of AppBarLayout
visible when status bar is transparent. Having an opaque status bar is not viable at all times. This happens on Lollipop & above only because of dynamic shadow rendering. On Marshmallow the wrong shadow looks even worse.
Best solution
Your root layout should have android:fitsSystemWindows="true"
at all times, otherwise your UI will not draw behind status bar.
Now wrap the AppBarLayout
inside another CoordinatorLayout
which has android:fitsSystemWindows="false"
. This will prevent the shadow from overflowing into statusbar
Other workarounds (not recommended)
In your Style remove the statusBarColor:
<item name="android:statusBarColor">@android:color/transparent</item>
So your theme would be:
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
</style>
Also you can simply make app:elevation="0dp" on appbarlayout, but that removes the shadow on bottom also.
