从android下载asmx webservice下载文件

Question

您好我想从webservice下载图片，我将此代码用于webservice：

 <WebMethod()> _
Public Function RC_GetImages(Code As Int32) As [Byte]()

    Dim ConSqlhi As New SqlConnection(My.Settings.connecttolocal)
    Dim cmd As New SqlCommand()

    cmd.Connection = ConSqlhi
    cmd.CommandType = CommandType.StoredProcedure
    cmd.CommandText = "GetImage"

    Try
        cmd.Parameters.Add("@code", SqlDbType.Int).Value = Code
        Dim dr As SqlDataReader = cmd.ExecuteReader()
        dr.Read()
        Dim ar As [Byte]() = DirectCast(dr(1), [Byte]())
        dr.Close()
        cmd.Dispose()
        Return ar

    Catch ex As Exception
        Dim a As [Byte]()
        Return a
        Exit Function

    End Try

    ConSqlhi.Close()

End Function      

我不知道怎样才能在android中获得这个图像 所以有人可以帮我这个吗？ image在我的数据库中，我从存储过程中获取它
