我正在构建一个具有通话功能的应用程序。因此，我从服务器收到通知，并且建立了一个活动来显示呼叫屏幕，其中有应答和挂断按钮。
现在我有一个问题，当应用程序处于后台/死机状态或手机被锁定时，应该使用什么来启动活动？
我试图在FirebaseMessagingService的onMessageRecieved函数中启动活动，但是我认为当应用程序在后台运行时不会调用该函数。因为当我在后台运行应用程序时尝试调试相同的对象时，不会触发调试指针并且活动也不会打开。
该活动在收到通知时在前台打开，但在应用程序在后台时打开。
这是我的服务

if(!myCustomKey?.length?.equals(0)!!)

createNotification(remoteMessage.data)

在显示通知之前添加此行
notificationBuilder.setFullScreenIntent(pendingIntent, true);
