I like to customize the native toastmessageshow by using CSBuilder. It works fine but there is on thing left attached bitmaps are not shown in the toast. Instead the B4X Logo is shown.
Example:
Dim cs As CSBuilder
cs.Initialize
cs.Alignment("ALIGN_CENTER")
cs.Append("Call Center")
cs.Append(CRLF)
cs.Image(xui.LoadBitmapResize(File.DirAssets, "attention.png", 24dip,24dip, True), 24dip, 24dip, True)
cs.Append(CRLF).Append(CRLF)
cs.PopAll
ToastMessageShow(cs,True)
