Call Live Wallpaper Within Application

I am trying to implement following thing in android 2.x. In my application i want to allow the user to create the custom live wallpaper kind of thing where user chooses few imag

Solution 1:

Maybe you should open this custom picking activity from within the standard "Settings" button a user sees when choosing your live wallpaper.

1. User goes into standard live wallpaper chooser, sees a list of installed LWPs, picks yours.
2. User sees your default implementation, chooses "Settings" button.
3. You show a list of settings, one of which is a PreferenceScreen named "Pick Images."
4. Assign an onClickListener to that preference item which launches your custom image picking activity.
