Class PollingScheduler

  • public class PollingScheduler
    extends android.content.BroadcastReceiver
    Schedules polling for updates from the Tapkey Trust Service. Most notably instances of this class poll for updated access keys on a periodic base. The app's Application instance must implement the TapkeyAppContext interface in order for this class to function. This class is used by registering it via its register(Context, int, int) method.
     PollingScheduler.register(this, uniqueJobId, PollingScheduler.DEFAULT_INTERVAL);

                                         int intervalMs)
        Registers polling for Tapkey notifications. The given jobId must be application-wide. The interval is approximate. The decision when the job will be executed will be made by Android itself and depends of several factors like battery level, network connection, etc.
        context - the Android Context.
        jobId - an application-wide unique job ID.
        intervalMs - the polling interval.
        a Closable which can deregister services and receivers. ToDo: Document why RECEIVE_BOOT_COMPLETED permission is required
