You don't have to write a whole long string to be used with .LoadHTML, I would rather create a small HTML and add it to my assets, in this case, you could save that line in a file called "calendar.html", then to use it, just do something like this:
B4X:
Private myHTML As String
myHTML = File.ReadString(File.DirAssets, "calendar.html")
WebView1.LoadHtml(MyHTML)
That way you don't have to worry about quotes and stuff like that.
