Changed file permissions in Donut 1.6 stops TRIAL software

Postby rdomloge » Tue Oct 13, 2009 5:38 pm

My trial software used to limit use to 100 uses. The number of times the user had used it was stored in

"/data/anr"

This worked great because this directory is not browseable, but it is writeable by applications. You could only read/write/delete the file if you knew the exact name of the file eg:

"/data/anr/banana.txt"

I could store the number of uses in this file and if the user uninstalled the app and re-installed it the app would still remember the number of times they used the app.

Problem is, in 1.6 they seem to have changed the permissions of this file and I cannot write to

"/data/anr/banana.txt"

any more. Short of accessing the network and transmitting the usage accross the internet to a license server, can anyone think of a way to replicate this?

Is there another directory with the same miraculous properties?
