Android : Why have I not automatically got theme.holo added to my android app

I have just put together an android app. I decided to write it from the terminal (os Ubuntu 14.04). So I managed to build and run my app with no real problems, but for some reason despite setting the minSdkVersion to 11 the app runs with no menubar and without using any of the holo theme type GUI graphics. It looks like a very old app indeed and I have no idea why. If I run the same code in my netbeans ide on a windows computer it applies theme.holo automatically.

I have not done anything fancy with my code it is just a basic app.. here is the manifest if you would like to peruse:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="self.redway.statechanges"
      android:versionCode="1"
      android:versionName="1.0">

      <uses-sdk minSdkVersion="11" targetSdkVersion="20"/>

    <application android:label="@string/app_name" android:icon="@drawable/ic_launcher">
        <activity android:name="StateChangesActivity"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

Any ideas anyone?
