[Sony Ericsson XPERIA X10 Mini] dams2011:
hello :) idea to add a live wallpaper on first boot

/device/semc/mimmi/overlay/frameworks/base/core/res/res/values/config.xml

config.xml add lines

<!-- Component name of the default wallpaper. This will be ImageWallpaper if not

specified -->

<string name="default_wallpaper_component">com.android.wallpaper/.nexus.NexusWallpaper</string>

<?xml version="1.0" encoding="utf-8"?>
