Send Code in B4j
B4X:
'Type MyMessage (Name As String, Age As Int, dbfile() As Byte)
Dim mm As MyMessage
mm.Initialize
mm.Age = edtAge.Text
mm.Name = edtName.Text
mm.dbfile = File.ReadBytes(File.DirApp,"1.mp3")
SendData (ser.ConvertObjectToBytes(mm))Receive code in B4a
B4X:
Dim mm As MyMessage = ser.ConvertBytesToObject(data)
edtAge.Text = mm.Age
edtName.Text = mm.Name
rp.CheckAndRequest(rp.PERMISSION_WRITE_EXTERNAL_STORAGE)
Wait For Activity_PermissionResult (Permission As String, Result As Boolean)
If Result = False Then
ToastMessageShow("No permission!",True)
Return
End If
'convert the array of bytes to file
File.WriteBytes(File.DirRootExternal, "1.mp3", data)
Sleep(100)
Log("File saved...")
If File.Exists(File.DirRootExternal, "1.mp3") Then
Log("File Found....")
Else
Log("File Not Found....")
End If
