make shortcut for livewallpaper select activity

I will make livewallpaer. For new android user, I want to offer shortcut for livewallpaper selection. In api, only image can set wallpaper. I cannot find livewallpaper set开发者_如何学运维 api. So, in activity, I want to do this thing.

1. set livewallpaper directly. or

2. show livewallpaper select activity(my device call com.android.wallpaper.livepicker/.LiveWallpaperListActivity )

.LiveWallpaperListActivity cannot call outside. android.intent.action.SET_WALLPAPER show chooser.

just show picture for how to set livewallpaper?

do you have some idea?

oops...
WallpaperManager.ACTION_LIVE_WALLPAPER_CHOOSER
can start livewallpaper setting.
I only search in Intent or log.
