I have started working on android recently and i have been looking at my colleagues code for an app to learn more.

I have come across this file which also has an error.

can you tell me what it is and what it does

```
<resources>

<!--
    Base application theme, dependent on API level. This theme is replaced
    by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
-->
<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
    <!--
        Theme customizations available in newer API levels can go in
        res/values-vXX/styles.xml, while customizations related to
        backward-compatibility can go here.
    -->
</style>

<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
    <!-- All customizations that are NOT specific to a particular API-level can go     here. -->
</style>

</resources>

```

error is in line 7
error retrieving parent for item,
no resource found that matches the given name "Theme.AppCompat.Light"
