ActionBar is missing after switching to API21 AppCompat

While working on the Big Nerd Ranch's Criminal Intent project when I updated my AppCompat library from API 19 to API 21 I lost ActionBar. I have tried changing themes around but I can't find a way to get ActionBar.

The full source code is available here.

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.sudhirkhanger.app.criminalintent" >

<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity android:name=".CrimeListActivity" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".CrimePagerActivity"
android:label="@string/app_name" >
</activity>
</application>

</manifest>


style.xml

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
</style>

</resources>


Thanks.

To use appcompat-v7, you must inherit from ActionBarActivity. CrimeListActivity inherits from SingleFragmentActivity, which in turn inherits from FragmentActivity, not ActionBarActivity.
