This file contains the themes that are the Device Defaults.
If you want to edit themes to skin your device, do it here.
We recommend that you do not edit themes.xml and instead edit
this file.

Editing this file instead of themes.xml will greatly simplify
merges for future platform versions and CTS compliance will be
easier.

    <!-- The dark default theme for apps that target API level XX and higher.
         <p>The DeviceDefault themes are aliases for a specific device’s native look and feel. The
         DeviceDefault theme family and widget style family offer ways for you to target your app
         to a device’s native theme with all device customizations intact.</p>
         <p>For example, when you set your app's {@code targetSdkVersion} to XX or higher, this
         theme is applied to your application by default. As such, your app might appear with the
         {@link #Theme_Material Material} styles on one device, but with a different set of styles on
         another device. This is great if you want your app to fit with the device's native look and
         feel. If, however, you prefer to keep your UI style the same across all devices, you should
         apply a specific theme such as {@link #Theme_Material Material} or one of your own design.
         For more information, read <a
         href="http://android-developers.blogspot.com/20XX/XX/material-everywhere.html">Material
         Everywhere</a>.</p>
         <p>Styles used by the DeviceDefault theme are named using the convention
         Type.DeviceDefault.Etc (for example, {@code Widget.DeviceDefault.Button} and
         {@code TextAppearance.DeviceDefault.Widget.PopupMenu.Large}).</p>
