Android - how to set the wallpaper image

Is it possible to set the android wallpaper image programatically? I'd like to create a service that downloads an image from the web and updates the home screen wallpaper periodically.

If you have image URL then use 

WallpaperManager wpm = WallpaperManager.getInstance(context);
InputStream ins = new URL("absolute/path/of/image").openStream();
wpm.setStream(ins);

If you have image URI then use 

WallpaperManager wpm = WallpaperManager.getInstance(context);
wpm.setResource(Uri.of.image);

In your manifest file:

<uses-permission android:name="android.permission.SET_WALLPAPER"></uses-permission>

OK Here's how to do it before api 2.0:

You need to call getApplicationContext.setWallpaper() and pass it the bitmap.

This method is now deprecated. See ChrisF's answer for details on the new method.

If you have bitmap of image than you will add this function to set as wallpaper:

  public void SetBackground(int Url) {

    try {
        File file = new File("/sdcard/sampleimage");
        Bitmap bitmap = BitmapFactory.decodeResource(getResources(), Url);
        bitmap.compress(CompressFormat.JPEG, 80, new FileOutputStream(file));
        Context context = this.getBaseContext();
        context.setWallpaper(bitmap);            
        Toast.makeText(getApplicationContext(), "Wallpaper has been set",             Toast.LENGTH_SHORT).show();            
    } catch (MalformedURLException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }         
}

you should add permission for this

<uses-permission android:name="android.permission.SET_WALLPAPER"></uses-permission>

hope it will work

From this page on the developer site:

public void setStream (InputStream data)

Change the current system wallpaper to a specific byte stream. The give InputStream is copied into persistent storage and will now be used as the wallpaper. Currently it must be either a JPEG or PNG image.
