Android Live Wallpaper guidance

When it comes to making Android live wallpaper, what are the things that are exactly needed. So far I could gist as WallpaperService.Engine, SurfaceView, some major changes in Android.manifest and xml/string.xml apart from this one png drawble (i think this may be optional if i use paint).

And what else do I need to develop whole different logic for the animation to happen? is it with mathematical calculations always? I am very keen about making different kind of live wallpaper. but i am not in the right track i think.

Please suggest me some way out to right direction summarizing me what all i need so that i can make any kind of live wallpaper.

Can somebody please summarize what all is needed for live wall paper.

Thanks in Advance.

Hi you can use this code if You have Image path.

is = new FileInputStream(new File(imagePath));
bis = new BufferedInputStream(is);
Bitmap bitmap = BitmapFactory.decodeStream(bis);
Bitmap useThisBitmap = Bitmap.createScaledBitmap(
bitmap, parent.getWidth(), parent.getHeight(), true);
bitmap.recycle();
if(imagePath!=null){
System.out.println("Hi I am try to open Bit map");
wallpaperManager = WallpaperManager.getInstance(this);
wallpaperDrawable = wallpaperManager.getDrawable();
wallpaperManager.setBitmap(useThisBitmap);

................................................. if you have image URI then use this

wallpaperManager = WallpaperManager.getInstance(this);
wallpaperDrawable = wallpaperManager.getDrawable();
mImageView.setImageURI(imagepath);

.............. Let me know if there is any issue .

Yes, you need to use a different approach for live wallpaper than "normal" animation in Android. The standard approach is to make a self-rescheduling runnable that draws to canvas.

In answer to one of your specific questions: no, you do not need to limit yourself to mathematical calculations; you can use bitmaps/sprites if you choose, but you will need to animate them yourself.

Your best place to start is the resources in the SDK:
