Only the original thread that created a view hierarchy can touch its views. error

Hello,
I don't know if you have already detected this : the error comes from txtkod.Text=Html
When you comment that line it works.

oh never suspected that. why does parsing a html code into a text makes a probem interesting :/
so how can i copy the code into a text or something what an i missing ? ideas ?

You need to show more real code (the one you are using)... I mean, you java-script calls in webview, the eventsub code...
I remember somthing that there is a true/false in the javascript call to indicate UI changes. So something like that...

It is the whole code. I got it from the example i posted in the first msg.

 Dim Javascript As String
   Javascript="B4A.CallSub('Process_HTML', false, document.documentElement.outerHTML)"

Try to set the second parameter to true

Please try this : it is a threading issue only

thanks for help fixed :=)

And this is most probably the correct way.

The Code from @lemonisdead will work too i guess (due to the delegating the ui changes with cllsubdelayed to the mainthread).

So let me ask you another question , what is the best possible way to get the lines i wanted. For example i want to get the value of 2.9201 (just below the line :
<td class="para">ABD DOLARI</td>

should i use the txtkod.text.contains and something like indexof to get it or is there a better way ? It is a bit off topic from the question but sorry

- You can use XOM and iterate through the code with it
- You can use regex to find the right code snippet)

Thank you very much

For parsing Html I often use jsoup library: https://www.b4x.com/android/forum/threads/jsoup-html-parser.49152/#post-309185; with this library, you can get HTML elements directly
