  This issue is related to android? Is it related to the UWP? I notfice your screenshot, This NewWallpaper in the PC not in android device or android emulator.

  Could your give me more information about it?
  I found a thread about change an image source based on conditions, you can refer to it.

  @LeonLu is related to android, I connected the my phone (samsung s7) on the pc and the screenshot is from the android path where I pasted the wallpaper.

  The main idea is to put differents wallpapers in a android folder, and everytime that I change the file the wallpaper should change too.

  Thanks!

  @LeonLu I find out a solution!

  public static string GetNewImg(string pImgName)
  {
  IFileSystemOperationsService fileService = DependencyService.Get();
  string fullPath = String.Empty;
  string lsResul = String.Empty;
  try
  {
  string imgpath = Android.OS.Environment.GetExternalStoragePublicDirectory(Android.OS.Environment.DataDirectory.Name).AbsolutePath;
  fullPath = imgpath + pImgName;
  }
  catch (Exception e)
  {
  }
  return lsresul;
  }

  And on every OnAppearing I do this:

  if (!(GetNewImg("BackGround1.jpg") == String.Empty))
  {

              BackGroudname.Source = GetNewImg("BackGround1.jpg");
  
          }
