I'm trying this code and get a blank screen instead. any ideas ?

Sub Activity_Create(FirstTime As Boolean)
    SQL1.Initialize(Main.dbFileDir, Main.dbFileName, True)
    Activity.Title = "Document Content"
    Activity.LoadLayout("DocumentFormView_LT")
    WebView1.Initialize("WebView1")
    WebView1.LoadHtml("<html><body>Hello world!</body></html>")

never mind, it was WebView.Initialize() statement causing problem. I removed it and it works.
This code was for testing, but now I replaced fixed HTML with the HTML which supposed to stored in TXT field in a table. I want to grab html code and place it in LoadUrl call so I can display a html page.

Sub Activity_Create(FirstTime As Boolean)
    SQL1.Initialize(Main.dbFileDir, Main.dbFileName, True)
    Activity.Title = "Document Content"
    Activity.LoadLayout("DocumentFormView_LT")
    'DocUrl = "file:///android_asset/" & DocumentList.selectedFile
    DocSource = SQL1.ExecQuery("SELECT HtmlSource FROM mDOCUMENTS WHERE ID="&DocumentList.SelectedRecord)
    WebView1.LoadHtml(DocSource)
    'WebView1.LoadHtml("<html><body>Hello World<br></body></html>")
    ProgressDialogShow("Loading " &DocUrl)
End Sub

this code instead of html page displays :

android.database.sqlite.SQLiteCursor@412a363

any ideas ?

never mind I forgat to read the cursor. for those who might have wondered ehre is the proper code to read an HTML source code and present it in a WebView:

Sub Activity_Create(FirstTime As Boolean)
    SQL1.Initialize(Main.dbFileDir, Main.dbFileName, True)
    Activity.LoadLayout("DocumentFormView_LT")
    Activity.Title = "Document Content"
    Cursor = SQL1.ExecQuery("SELECT ID, HtmlSource FROM mDOCUMENTS WHERE ID="&DocumentList.SelectedRecord)
        For i = 0 To Cursor.RowCount - 1
            Cursor.Position = i
            DocSource = Cursor.GetString("HtmlSource") 
        Next
    WebView1.LoadHtml(DocSource)
    ProgressDialogShow("Loading " &DocUrl)
End Sub

I still need to parse the image location...
