I think this capability REALLY needs to be looked into. Live wallpaper is way too popular to ignore, and everyone wanting to get into Android development will want to start with simple Live Wallpaper apps. B4A is still totally AWOL on this, and it is an extremely high demand item in the Android world.
What we need:
1. The basic ability to cycle images as live wallpaper (just recently provided by using timers with the simple LiveWallpaper library from XverhelstX - MAJOR kudos, at least it gets the ball rolling!).
2. The ability to play animated GIFs or movie clips as the live wallpaper. This is already being done out there (see the Market app called AnimGIF). Badly need at least this capability.
3. The ability to play looping movie clips as live wallpaper. This probably means the next item needs to be realized as well:
4. The ability to be able to use a full B4A app itself (complete with layout) as the live wallpaper, which would allow us to write any type of live wallpaper we could ever dream of (not just image cyclers).
Live Wallpaper sells extremely well on the Market, and the B4A community is PAINFULLY missing out here.
Please consider this a down-on-knees, groveling, begging, boot-licking plea for the ability to get some really good LWP functionality into B4A.
