I am using this example by Erel
https://www.b4x.com/android/forum/threads/37201/#content and it works fine in it's original form. I am trying to send a file( a map) to the server (that works ok) do some work on the map and then send it back to the device ... that's my problem sending it back.
I don't fully understand how the example works so i'm 'shooting in the dark', i have searched the forum and tried may different ways but can't send the map back. I was hoping to work this out myself but i now have to ask for some help. Thanks Dave.
