Android - how to set the wallpaper image

Question

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>
