    Expiration date implementation

    Hi!

    I would like to protect my application by having an expiration date after which the application will stop working. The problem is the same as with signed applications - user can freely change the time in the phone. Does anyone know if it is possible to protect against this issue?

    Is it possible to use DRM Right Object and create it at runtime after application installation? Or the only possibility is to use Separate Delivery/Combined Delivery?

    Re: Expiration date implementation

    you could always keep track on what time values has been used, so if the time is before the last time you saw, then just inform user and stop working.
