Когда я использую Intent вне onStartCommand () службы, чтобы показать уведомление о конкретном событии, он показывает getApplicationContext на нулевой ссылке на объект.Сервис позволяет только использовать getApplcationContext / this / context внутри метода onStartCommand ().Как я могу использовать его вне метода onStartCommand ()?Ниже мой сервис.Может ли кто-нибудь помочь мне с этим?
