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”.

Alright, just so I stop getting downvotes for an outdated answer. Please see Error 454’s answer below for a more robust solution which will send the user directly to the wallpaper preview screen on Jelly Bean and up devices.
========================================
Here’s how to start the wallpaper chooser, from which the user can select your wallpaper. The toast is just a way to explain to the user what’s going on.
Toast toast = Toast.makeText(this, “Choose ” from the list to start the Live Wallpaper.”,Toast.LENGTH_LONG);
toast.show();
Intent intent = new Intent();
intent.setAction(WallpaperManager.ACTION_LIVE_WALLPAPER_CHOOSER);
startActivity(intent);
