Google GCM을 사용해 보았지만 앱이 닫히면 (작업 관리자에서 스 와이프하거나 지울 때) 푸시 알림을받지 못합니다. 그리고 앱을 다시 열면 알림이 이미 사라져 버렸습니다.앱이 닫혀 있어도 Android 푸시 알림 수신
GCM을 위해 노력하고 있습니다 : - 응용 프로그램이 열려 입니다 - 응용 프로그램이 작동하지
최소화 : 을 - 응용 프로그램은 (작업 관리자에서 슬쩍) 닫혀 - 응용 프로그램은 작업 관리자에서 일반 열려있는 모든 응용 프로그램을 통해 폐쇄
앱이 Facebook이나 인스 타 그램처럼 닫혀 있어도 푸시 알림을 받고 싶습니다. 나는 이것을 어떻게 얻을 수 있을까 ?? GCM에서도 가능합니까? 그렇다면 어떻게? 그렇다면이 것을 달성하는 다른 방법은 무엇입니까 ??

서비스를 사용하거나 가능한 가장 좋은 방법은 알람 관리자가있는 브로드 캐스트 수신기를 사용하는 것입니다. 알림을 위해 시간을 설정하십시오. 클래스에 설정하려는 내용이 있습니다. –
브로드 캐스트 리시버를 작성 했습니까? –
방송 수신기 만 있으면 충분합니다. –
