You simply do not have a style file with the AppTheme theme declared
Create a file named styles .xml.
Paste this content into it.
(The filename is arbitrary, that is, whatever ... you choose)
<?xml version="1.0" encoding="utf-8"?>
<style name="AppTheme" parent="android:Theme.Light">
</style>
The above theme is as simple as possible.
If you want to learn more about current themes, using Material Design for example, search the compatibility library version 7 (appcompat7)
With it, your theme would look like this (with lollipop design)
<?xml version="1.0" encoding="utf-8"?>
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
</style>
