Sorry man, it's my fault. I forgot to put in a new B4AExample project after some system stuff related to Custom View properties was replaced in the library. The problem in B4AExample has been solved by deleting the UltimateWebView object through the designer and adding a new one. Get the new B4AExample from first post. Thanks again for pointing me to the problem.

Can I suggest that you move the description - the motivation that led you to develop this library - to the beginning of the thread, rather than after the very long list of its members?

Okay, thank you for the useful advice. I will consider how to redesign the first post because the references are really very long. Maybe I'll remove the references from the first post.

Very strange, I tested on Android 11, 10, 9, 7 and 6 and it works without problems. I'll check again to see what could be causing the problem. Have you tried downloading the new B4AExample and uninstalling the old one before installing?

Version 2.12 released. Download library and documents from first post.

Changes:
  • Edited method LoadHTMLString (HTMLString As String)
    • Fixed a bug that in some cases this method did not display the contents of the HTML string.
  • Edited method LoadFileFromDirAssets (FileName As String, IncludeSubFolders As Boolean)
    • IncludeSubFolders As Boolean - True for an html file whose objects are in a subfolder or multiple subfolders. False for an html file that has no additional objects in the subfolders but only at the root of the Asset folder. For a non html files value is not important (True or False).
    • It is now possible to use the standard file scheme to open files in subfolders through an HTML file. E.g:
    • Example:: 
      "file:///android_asset/subfolder/file.png"
  • Method SetWebChromeClient become property WebChromeClientEnabled (true or false).
    • B4X: 
      UltimateWebView1.SetWebChromeClient  'old
'Replace with
UltimateWebView1.WebChromeClientEnabled=True 'or False for disable
  • Method SetWebViewClient become property WebViewClientEnabled (true or false).
    • B4X: 
      UltimateWebView1.SetWebViewClient  'old
'Replace with
UltimateWebView1.WebViewClientEnabled=True 'or False for disable
  • Method SetDownloadListener become property DownloadListenerEnabled (true or false).
    • B4X: 
      UltimateWebView1.SetDownloadListener  'old
'Replace with
UltimateWebView1.DownloadListenerEnabled=True 'or False for disable
  • The method FileChooserStart (for file upload) now starts the application chooser instead of the default file chooser.

Hi @Ivica Golubovic, you know because initializing JSInterface inside a Class this way fails?
B4X: 
JSInterface.Initialize(Me)

I still search to port this @stevel05 library to B4A but app crashes on this line.
https://www.b4x.com/android/forum/threads/codemirror-wrapper-and-example.125775/

Log do not help, just says: Error occurred on line: 147 (CodeMirrorWrapper)

Many Thanks

Here the unfiltered log, for sure you are better than me to know it.

Thanks for reply,

maybe I found a mistake, I used this line in the DesignerCreateView where @stevel05 initialized a B4J Javascript using JavaObject and webEngine. Maybe don't like it?

What I do not know is because the UltimateWebView can be initialized with Me but JSInterface no.

Here a relevant code...
If you need I can send all class.

Many thanks

B4X: 
In Class_Globals:  Public JSInterface As UltimateJavascriptInterface

Public Sub DesignerCreateView (Base As Object, Lbl As Label, Props As Map)

    mBase = Base
    Tag = mBase.Tag
 
    'Initial Values
    mWidth = mBase.Width
    mHeight = mBase.Height

    mBase.LoadLayout("codemirrorwrapper")
 
    mBase.Tag = Me
 
    ''''''''''''''''''''''''''''' SETUP B4J JS '''''''''''''''''''''''''''''''

First try not to initialize JSInterface to Designer sub. If that doesn't work, let me know so I can check the library code tomorrow.

Sorry, I don't known it, what is Designer sub ?

Maybe you intend inside a class initializer ?
B4X: 
Public Sub Initialize (Callback As Object, EventName As String)
