Setting live wallpaper programmatically

Question

Is it possible to set a live wallpaper using some lines of code. For example, i want to tell my users that a live wallpaper is available "click here to set it".

Answer 1

There are now two ways to accomplish this as Jelly Bean provides a way to directly set the live wallpaper. This boilerplate code will choose the best method available.

Intent i = new Intent();

if(Build.VERSION.SDK_INT > 15){
    i.setAction(WallpaperManager.ACTION_CHANGE_LIVE_WALLPAPER);

    String p = HypercaneWallpaperService.class.getPackage().getName();
    String c = HypercaneWallpaperService.class.getCanonicalName();        
    i.putExtra(WallpaperManager.EXTRA_LIVE_WALLPAPER_COMPONENT, new ComponentName(p, c));
}
else{
    i.setAction(WallpaperManager.ACTION_LIVE_WALLPAPER_CHOOSER);
}
getActivity().startActivityForResult(i, 0);
