我想在收到FCM的通知后开始一项活动。它在应用程序的前台运行良好，但当我在android中移动活动时，我只会在系统托盘中收到通知。
正如我所做的调试一样，onMessagereceived在应用程序处于前台时被调用，但在应用程序位于后台时不会被调用。
class MyFirebaseMessagingService : FirebaseMessagingService() {
// [START receive_message]
private var mRemoteMessage: Map<String, String>? = null
override fun onMessageReceived(remoteMessage: RemoteMessage) {
// Check if message contains a data payload.
if (!remoteMessage.data.equals("")) {
Log.d(TAG, "Message data payload: " + remoteMessage.getData());
}
// Check if message contains a notification payload.
if (remoteMessage.getNotification() != null) {
Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification()!!.getBody());
remoteMessage.data.get("notification_data")?.let { sendNotification(it) };
val broadcast = Intent();
broadcast.setAction("OPEN_NEW_ACTIVITY")
sendBroadcast(broadcast)
}
}
private fun sendNotification(messageBody: String) {
val intent = Intent(this, NotificationActivity::class.java)
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)
val pendingIntent = PendingIntent.getActivity(
this, 0, intent,
PendingIntent.FLAG_ONE_SHOT
)
val channelId = getString(R.string.default_notification_channel_id)
val defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)
val notificationLayoutExpanded = RemoteViews(packageName, R.layout.activity_notify)
val notificationBuilder = NotificationCompat.Builder(this, channelId)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle(getString(R.string.fcm_message))
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent)
.setFullScreenIntent(pendingIntent,true)
.setCustomBigContentView(notificationLayoutExpanded)
.setStyle(NotificationCompat.DecoratedCustomViewStyle())
val notificationManager = getSystemService(Context.NOTIFICATION_SERVICE)
as NotificationManager
// Since android Oreo notification channel is needed.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val channel = NotificationChannel(
channelId,
"Channel human readable title",
NotificationManager.IMPORTANCE_HIGH
)
notificationManager.createNotificationChannel(channel)
}
notificationManager.notify(0, notificationBuilder.build())
}

当在后台收到通知时，请建议我可以做些什么来启动活动。？
您在通知中发送了数据。通知只处理应用程序的前台，而不是您在有效负载中发送数据的通知。以及基于有效载荷消息的开放活动
override fun onMessageReceived(remoteMessage: RemoteMessage) {
super.onMessageReceived(remoteMessage)
val data = remoteMessage.data
if (remoteMessage.data.isNotEmpty()) {
Log.d(TAG_FIREBASE, "Message data payload: ${remoteMessage.data}")
//open activity
}}
而且这取决于你的设备你测试这个服务
