Following the documentation, you need to change the colorPrimaryDark there are several ways to do, you can create your own theme or modify the existing one, you can implement in XML or in auto-creation form.

Following are examples:

values/themes.xml:

<style name="Theme.MyTheme" parent="Theme.AppCompat.Light">
    <!-- Here we setting appcompat’s actionBarStyle -->
    <item name="actionBarStyle">@style/MyActionBarStyle</item>

    <!-- ...and here we setting appcompat’s color theming attrs -->
    <item name="colorPrimary">@color/my_awesome_red</item>
    <item name="colorPrimaryDark">@color/my_awesome_darker_red</item>

    <!-- The rest of your attributes -->
</style>

or in Layout

<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="wrap_content"
    android:background="?attr/colorPrimaryDark"/>

Here a good material study.
