Hi,
I'm using LabelExtra for showing some HTML content. Everything is working fine but getting an error while showing img tag.
Here is the code:
Getting this error:
If I use wait for (getImage) complete(result as object) then I have to change the return type of Sub ImageGetter_GetDrawable(Source As String) As Object to resumable sub. But as per the library example this return type has to be an Object.
So is there any solution?
