java - How to update an activitys background when it's set to the systems wallpaper? -

I have this code which allows me to set the current device wallpaper to be my activity background.

  Public Zero Wallpaper Background () (WallpaperManager WallpaperManager = WallpaperManager.Testinstance (this); Drawing WallpaperDrawable = Wallpaper Manager.getDrawable (see; View Root = Find VeeById (R.id.home_view); root.setBackground ( WallpaperDrawable);}  

The problem is, if I have to go through settings I do not update the wallpaper on my app and I have been left with the previous wallpaper how can I fix it?

It's really quite simple:

Just call your wallpaperBackground () in the method onResume () In your activity.

This will automatically apply the correct wallpaper when the user will restart the activity from another app.
