This code is no longer needed. Use File.WriteBytes / ReadBytes. Write an array of bytes to a file and read a file into an array of bytes. Sub BytesToFile (Dir As String, FileName As String, Data..., 0, Data.Length) out.Close End Sub Sub FileToBytes (Dir As String, FileName As String) As Byte() Return Bit.InputStreamToBytes(File.OpenInput(Dir, FileName)) End Sub Note that you can convert complex objects (and simple objects) to bytes and vice versa with B4XSerializator from...
