SOLVED - By adding the Micro SD card dropbox created folder automatically on that and now the downloads are working.
So anyhow still not got dropbox working so i have a ticket raised with dropbox and although slow the boys are very professional and iv submitted my error log however I always like to have a look my self after many years working in technical support you learn a few things.
I had to send the log error to drop box I wont post all of it here.
and perhaps a few questions.
I have 5 pdf files currently 50mb in my dropbox account however my account is 50gb do you think dropbox is trying to make 50g worth of space on the nand drive - far fetched but possible.
The odd error logs:
Couldn't create directory: null/dropbox for file null/dropbox/0195388542Brain.pdf
Now im sure this might be to do with WRX permissons on the file that dropbox creates?
point 2
0195388542Brain.pdf
java.io.FileNotFoundException: /null/tmp/dropbox/file0.tmp
seems to be a missing file of some sort googled java.io but nothing really came up.
any suggestions to what these might be?
