Changing default theme


#1

I am looking to change the default theme in res > values > styles.xml file:

<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/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

</resources>

Every time I start a new project I need to change the first line to:

<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">

I am tired of having to do this every time I create a new project. I am looking to find the location stored in my file system to make this change to apply to all future new projects, or a way to configure the default settings.

I know how to change themes, but only after the project has been created. I would like to know where these values are stored, or a way to change defaults to avoid this extra step.
