Hi,

I added a sub in dbutils : executehtml(2) in this I add a col( with image ) to the webview as linkable.
now i changed the image deleted the old one from the projectfolder i uninstalled the project from my device. still i get the old image to see. the "clear cache" method found in this forum is not functioning for me. where do i find (with ex. ES file explorer) the stored images in my device to delete manualy?

below the code from my executehtml2 clikkking on the image i'm capable to get the values from the cols with the sub WebView1_OverrideUrl using ''~" for the split...etc...


B4X:
Sub ExecuteHtml2(SQL As SQL, Query As String, StringArgs() As String, Limit As Int, Clickable As Boolean) As String
    'as ExecuteHtml but extra <td> with value as link. with ~ as split

    Dim Table As List
    Dim cur As Cursor
    If StringArgs <> Null Then
        cur = SQL.ExecQuery2(Query, StringArgs)
    Else
        cur = SQL.ExecQuery(Query)
    End If
    Log("ExecuteHtml2: " & Query)
    If Limit > 0 Then Limit = Min(Limit, cur.RowCount) Else Limit = cur.RowCount
    Dim sb As StringBuilder
    sb.Initialize
    sb.Append("<html><body>").Append(CRLF)
    sb.Append("<style type='text/css'>").Append(HtmlCSS).Append("</style>").Append(CRLF)
    sb.Append("<table><tr>").Append(CRLF)
    For i = 0 To cur.ColumnCount - 1
        sb.Append("<th>").Append(cur.GetColumnName(i)).Append("</th>")
    Next
    sb.Append("<th style='width:30px align=center'>").Append("M/D").Append("</th>")
    sb.Append("</tr>").Append(CRLF)
    ColCount=0

    For row = 0 To Limit - 1
        cur.Position = row
        'If row Mod 2 = 0 Then
        '    sb.Append("<tr class='odd'>")
        'Else
            sb.Append("<tr class='odd'>")
        'End If
    
        ColCount=cur.ColumnCount
        For i = 0 To cur.ColumnCount - 1
            sb.Append("<td>")
            If Clickable Then
                sb.Append(cur.GetString2(i))
            Else
                sb.Append(cur.GetString2(i))
            End If
            sb.Append("</td>")
        Next
        sb.Append("<td style='width:30px' Align='Center'>")
        sb.Append("<a href='http://")
        For t=0 To cur.ColumnCount-1
            sb.Append(cur.GetString(cur.GetColumnName(t)))
            sb.Append("~")
        Next
        sb.Append(".com'>")
        '<img src='file:///android_asset/question.png'/>
        'sb.Append("Edit</a>")
        sb.Append("<img src='file:///android_asset/edit.jpg' width=50 height=30 /></a>")
        sb.Append ("</td>")
        sb.Append("</tr>").Append(CRLF)
    Next
    cur.Close

    sb.Append("</table></body></html>")
    Return sb.ToString
End Sub

extra info:
in settings of my device cleared the cash (result still the same)
-
When I install the app with "Release" than the new image is showing.
When I instal the app with debug (rapid) still the old image is showing.

i changed the line:

sb.Append("<img src='file:///android_asset/edit.jpg' width=50 height=30 /></a>")

in following and it's working in debug(rapid)!​

sb.Append("<img src='" & WebViewAssetFile("view.gif") & "' width=50 height=30 /></a>")
