After testing all the options the only way that worked for my project is the following.
WebView1.LoadHtml("<html><body><img src='file:///android_asset/chrysanthemum.jpg'/></body></html>")
I also want to make one more question if you can help my. If VB.NET you can place the " character in a string by typing it twice. For expample you can have a string variable like this:
Dim MyString as String = "My name is ""Manos"" and I am from Greece"
This has as a result to store in the string the following value:
My name is "Manos" and I am from Greece
Also there is a constant for changing line in a string called vbCrLf. Is there a way to put the CrLf in a string like a constant or like a code inside the string.
