Re: [android-developers] LVL, ServerManagedPolicy...

The lifetime of the cache used by ServerManagedPolicy is controlled by the server (as the name suggests), and has three variables:

VT	License validity timestamp. Specifies the date/time at which the current (cached) license response expires and must be rechecked on the licensing server.
GT	Grace period timestamp. Specifies the end of the period during which a Policy may allow access to the application, even though the response status is RETRY. The value is managed by the server, however a typical value would be 5 or more days.
GR	Maximum retries count. Specifies how many consecutive RETRY license checks the Policy should allow, before denying the user access to the application. The value is managed by the server, however a typical value would be "10" or higher.

The cache is valid as long as (currentTime < VT)  && (currentTime < GT || retryCount < GR).

This is documented here: http://developer.android.com/guide/publishing/licensing.html#extras

Hi,
I'm using the ServerManagedPolicy implementation from the LVL code
sample (MainActivity.class) but I haven't understood how it manage
cache.

The first time application start it needs internet to validate the
license, if it is validated, how much time should pass before a second
check is needed?

Thanks.
