How do I detect whether my live wallpaper is running in the preview/"Set Wallpaper" activity or on the homescreen

Question

I'd like to draw a text message only when the wallpaper is run from the live wallpaper selection app, in the preview activity. (With the "Set Wallpaper" and "Settings" buttons).

Since I'll have a free and paid version, in the free one I'd also like to make the user aware of the paid versions features, or even enable those features while previewing the wallpaper, but not when it's actually running on the homescreen to avoid annoying them.

Any ideas?

As an alternative, I might just display this information the first time the wallpapers is launched, which will always be from the preview activity.

use isPreview() within your onCreateEngine() method.
