Default About creating trial version of utility app

Please Login to Remove!

Hi All,
I want to create a 15 day trial version of a Blackberry application. The application should not involve connectivity to server for full version activation. Also the application should not work after 15 days even after reinstalling the application.

Any idea how can I implement them on OS 4.5? Any suggestions will be appreciated. Thanks in advance.

Are you using the Blackberry App World? If so, you are going to need to create a dynamic licensing model; this involves having the blackberry app world request a key from your webserver when the user downloads the application. Check out this document: http://na.blackberry.com/eng/develop...cense_Flow.pdf

Your server keeps track of the license keys and when they were issued, and whenever you make a request to your server you can submit the license key as a parameter and check to see if it is valid. Or, you could just check it once when the application is launched. If the license key has expired, just respond with an error code to your blackberry application.
