    START_NOT_STICKY
    Do not recreate the service, unless there are pending intents to deliver. This is the 
    safest option to avoid running your service when not necessary and when your application 
    can simply restart any unfinished jobs.
    START_STICKY
    Recreate the service and call onStartCommand(), but do not redeliver the last intent. 
    Instead, the system calls onStartCommand() with a null intent, unless there were pending 
    intents to start the service, in which case, those intents are delivered. This is suitable 
    for media players (or similar services) that are not executing commands, but running 
    indefinitely and waiting for a job.
    START_REDELIVER_INTENT
    Recreate the service and call onStartCommand() with the last intent that was delivered 
    to the service. Any pending intents are delivered in turn. This is suitable for services 
    that are actively performing a job that should be immediately resumed, such as downloading a file.
