How to use getCropAndSetWallpaperIntent method in WallpaperManager?

Question

I want to know how to use the getCropAndSetWallpaperIntent method in the WallpaperMannager class

I use it as follows:

 getCropAndSetWallpaperIntent(Uri.fromFile(new File(wallpaper_path))); 

But this throws an exception:

  java.lang.IllegalArgumentException: Image URI must be of the content scheme type 

How can i fix this?
