我已经在我的应用中实现了Onesignal Push通知，但是当我的应用关闭时，我没有收到推送通知。这是我的实施代码。

注意 - 请忽略java文件中不必要的方法调用。我刚刚显示了与OneSignal推送通知相关的代码。 为什么我的应用关闭时无法收到通知？
答案 0 :(得分：2)
如果您通过将应用程序置于“强制停止”状态来关闭应用程序，则不会收到包括推送通知的GCM / FCM消息在内的大多数事件。可以通过以下方式将应用程序置于此状态。
要确认您的应用状态是问题，请发送一些通知并检查以下GCM logcat条目。
W/GCM-DMM: broadcast intent callback: result=CANCELLED forIntent { act=com.google.android.c2dm.intent.RECEIVE pkg=com.onesignal.example (has extras) }
某些设备制造商将白名单应用程序进入强制关闭状态。例如Gmail和Whatsapp。
