You can use wallpaper manager to set image as wallpaper.

WallpaperManager myWallpaperManager
     = WallpaperManager.getInstance(getApplicationContext());
    try {
     myWallpaperManager.setResource(R.drawable.wallpaper);
    } catch (IOException e) {
     // TODO Auto-generated catch block
     e.printStackTrace();
    }

   }});
