You should add a line to your AndroidManifest that says you are using a theme (standard android or advanced)
<application android:name=".YourAppNameHere" android:label="@string/app_name" android:icon="@drawable/icon" android:theme="@style/MyTheme">
and then you can have topic.xml in your res / values / folder, where you expand: Theme.NoTitleBar and add custom rules to them (like windowBackground for example)
<resources> <style name="MyTheme" parent="android:Theme.NoTitleBar"> <item name="android:windowBackground">@drawable/my_background</item> </style> <resources>
Good luck
