私が推測する構成が欠落しているはずですが、見つかりませんでした。メインアクティビティにアクションバーを表示するための私の変更に従います。
1 - ルート アクティビティの ActionBarActivity を拡張します。
public class MainActivity extends ActionBarActivity implements OnItemSelectedListener {
2 - minsdkversion を 11 に更新
<uses-sdk
android:minSdkVersion="11"
android:targetSdkVersion="18" />
3 - サポート ライブラリ android-support-v7-appcombat.jar を追加します。
4 - メニュー xml を変更します。
<?xml version="1.0" encoding="utf-8"?>
<menu
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:yourapp="http://schemas.android.com/apk/res-auto"
>
<item
android:id="@+id/action_aboutbox"
android:orderInCategory="100"
android:showAsAction="always"
android:title="@string/action_aboutbox"/>
<item
android:id="@+id/action_exit"
android:orderInCategory="100"
android:showAsAction="always"
android:title="@string/action_exit"/>
</menu>
