any help is highly appreciated

try

Sub WebViewClient_PageStarted(Url As String, FavIcon As Object)
dim ficon as bitmap = FavIcon
' work with ficon
end sub

 

[Devv]

try

Sub WebViewClient_PageStarted(Url As String, FavIcon As Object)
dim ficon as bitmap = FavIcon
' work with ficon
end sub

seems to work !

can you please explain why we needed to declare it as an object ?

i was using the event from the documentation , it is by default as bitmap

 

[DonManfred]

probably because the b4a Bitmap is different to the bitmap Object from Android. B4A Bitmap is a wrapper.
Defining the sub signature as FavIcon As Object takes the parameter (whatever it is).
the next line then creates a wrapperobject and passes the Android Bitmap (encapsulated in the Object).

OK DonManfred
