Android: Enable hardware acceleration

I want my animations in android 4.0 is very slow and lacks. So I want to enable hardware acceleration and have tried to do what this page says but with no luck.

You can see my manifest here:

<?xml version="1.0" encoding="UTF-8"?>
<manifest android:versionCode="1" android:versionName="1.0"
    package="com.jws.battleship" xmlns:android="http://schemas.android.com/apk/res/android">
    <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="15"/>
    <uses-permission android:name="android.permission.BLUETOOTH"/>
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
    <application 
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" 
        android:theme="@android:style/Theme.Black.NoTitleBar"
        android:hardwareAccelerated="true">
        <activity 
            android:label="@string/app_name" 
            android:name=".HomeActivity"
            android:hardwareAccelerated="true">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
        <activity android:name=".UserPreferences"/>
        <activity android:name=".BattleActivity" android:screenOrientation="landscape"/>
        <activity android:name=".HighScoreActivity"/>
        <activity android:name=".StoreActivity"/>
        <activity android:name=".JoinBattle"/>
        <activity android:name=".CreateBattleActivity"/>
        <activity android:name=".FriendList"/>
        <activity android:name=".FriendListActivity"/>
        <activity android:name=".SelectNetworkActivity"/>
        <activity android:name=".BluetoothDevicesListActivity"/>
        <activity android:name=".NetworkFactoryActivity"/>
    </application>
</manifest>

I then test if it has enabled hardware acceleration in onCreate() like this:

ListView list = (ListView)findViewById(R.id.home_list_active_games);
Boolean test = list.isHardwareAccelerated();

But it always returns false!? Do I need to add some kind of permission or what is wrong here?

Change this to 

<uses-sdk android:minSdkVersion="11" android:targetSdkVersion="15"/>

Using hardware acceleration requires minSdkVersion 11 or higher.

The above code looks ok. The same problem is posted at HoneyComb isHardwareAccelerated() always returns false. Yet Android 3.0 Hardware Acceleration writes

If you need more fine-grained control, you can enable hardware acceleration for a given window at runtime:

    getWindow().setFlags(
    WindowManager.LayoutParams.FLAG_HARDWARE_ACCELERATED,
    WindowManager.LayoutParams.FLAG_HARDWARE_ACCELERATED);
