Interface LicenseCheckerCallback

public interface LicenseCheckerCallback

Callback for the license checker library.

Upon checking with the Market server and conferring with the Policy, the library calls the appropriate callback method to communicate the result.

The callback does not occur in the original checking thread. Your application should post to the appropriate handling thread or lock accordingly.

The reason that is passed back with allow/dontAllow is the base status handed to the policy for allowed/disallowing the license. Policy.RETRY will call allow or dontAllow depending on other statistics associated with the policy, while in most cases Policy.NOT_LICENSED will call dontAllow and Policy.LICENSED will Allow.

Method Detail

allow

void allow(int reason)

Allow use. App should proceed as normal.

Parameters:

reason - Policy.LICENSED or Policy.RETRY typically. (although in theory the policy can return Policy.NOT_LICENSED here as well)

dontAllow

void dontAllow(int reason)

Don't allow use. App should inform user and take appropriate action.

Parameters:

reason - Policy.NOT_LICENSED or Policy.RETRY. (although in theory the policy can return Policy.LICENSED here as well --- perhaps the call to the LVL took too long, for example)

applicationError

void applicationError(int errorCode)

Error in application code. Caller did not call or set up license checker correctly. Should be considered fatal.
