iOS Question Get Broadcast Address for B4i

[Nitin Joshi]

I am using following code in B4A to get broadcast address of the network. However, as JavaObject is not supported in B4i, i want sub for B4i. Thank you.

Private Sub Get_Broadcast_Address As String

    Dim niIterator As JavaObject

    niIterator = niIterator.InitializeStatic("java.net.NetworkInterface").RunMethod("getNetworkInterfaces", Null)

    Do While niIterator.RunMethod("hasMoreElements", Null)

        Dim ni As JavaObject = niIterator.RunMethod("nextElement", Null)

        If ni.RunMethod("isLoopback", Null) = False Then

            Dim addresses As List = ni.RunMethod("getInterfaceAddresses", Null)

            For Each ia As JavaObject In addresses

                Dim broadcast As Object = ia.RunMethod("getBroadcast", Null)

                If broadcast <> Null Then

                    Dim b As String = broadcast

                    Return b.SubString(1)

                End If

            Next

        End If

    Loop

    Return ""

End Sub

You don't need that code.

Dim usocket As UDPSocket
Log(usocket.GetBroadcastAddress) 'no need to initialize usocket for this method.
