    Attached is a simple project that load a webpage in a webview and using the findAll RunMethod2 search and highlight all words searched. It's ok!
    Why Log(FindAll(WebView1, word)) always return 0?
    I need count the number of occurrences the word found..
    How I can do this?
    What is wrong in the code?
    Any tips?

    Why is the project named Erel? This is not needed. This is a community forum. All members can help you.

    Sorry Erel! I forgot to rename the project before posting. I will correct this.... My doubt is addressed to the whole community. Can you help anyway?

    You must use findAllAsync with a listener:
    Sub Globals
    Private btnFind As Button
    Private EditText1 As EditText
    Private WebView1 As WebView
    Private FindListener As Object
    End Sub

    Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    Dim jo As JavaObject = WebView1
    FindListener = jo.CreateEventFromUI("android.webkit.WebView.FindListener""FindListener"Null)
    End Sub

    Sub btnFind_Click
    Dim word As String = EditText1.Text
    Dim jo As JavaObject = WebView1
    Do While True
    Wait For FindListener_Event (MethodName As String, Args() As Object)
    Dim ActiveMatchOrdinal As Int = Args(0'ignore
           Dim NumberOfMatches As Int = Args(1)
    Dim IsDoneCounting As Boolean = Args(2)
    If IsDoneCounting Then Exit
    Log("Total matches: " & NumberOfMatches)
    End Sub
