这是我有趣的问题.当应用未运行时,来自GCM的Android通知未显示标题和内容(仅显示应用名称,并在单击时打开MainActivity).

但是当应用程序打开时,它会成功显示标题和内容.可能是什么问题？它运行没有问题,我没有改变任何东西.

我有迁移gcm to fcm推送通知消息.但我如何从RemoteMessage获取捆绑数据收到onMesssageReceived方法.

Old GCM give bundle data onMessageReceiced method but in FCM there is RemoteMessage data.

所以请告诉我如何解析remotemessage获取所有通知值.

我在通知栏上发送了一些通知,我希望在点击其中一个通知时清除所有通知.现在我通过使用Flag逐个清除.我知道notificationManager.cancelAll()可以清除所有通知但我应该放在哪里,以便一旦点击通知之一我就可以触发.

 private static void generateNotification(Context context, String message) {
    int icon = R.drawable.ic_launcher;
    long when = System.currentTimeMillis();
    NotificationManager notificationManager = (NotificationManager)
            context.getSystemService(Context.NOTIFICATION_SERVICE);
    Notification notification = new Notification(icon, message, when);
    String title = context.getString(R.string.app_name); 
    Intent notificationIntent = new Intent(context, MainActivity.class);

    // set intent so it does not start a new activity
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
            Intent.FLAG_ACTIVITY_SINGLE_TOP);
    PendingIntent intent =
            PendingIntent.getActivity(context, 0, notificationIntent, 0);
    notification.setLatestEventInfo(context, title, message, intent);
    notification.flags |= Notification.FLAG_AUTO_CANCEL;

    notificationManager.notify(msgid, notification);  
    //notificationManager.cancelAll(); //i wan to clear all when the notification …

我已经用这个问题撞了桌子3天了,请告诉我我误入歧途的地方.

当我收到传入的VoIP电话时,我正在尝试显示全屏通知,就像PhoneApp那样.如果用户处于身临其境的活动中,我可以抬起头来.但是,我只收到抬头通知,并且从未获得全屏.我也需要通知忽略锁定屏幕.

这是我在做的事情:

    String callJson = call.toJson(uber).toString();
    uber.requestWakeState(UberVoice.WAKE_STATE_FULL);

    final Notification.Builder builder = new Notification.Builder(uber);
    builder.setSmallIcon(R.drawable.switch_notification);
    if (image != null) {
        builder.setLargeIcon(image);
    }
    builder.setOngoing(true);

    PendingIntent inCallPendingIntent =
            PendingIntent.getActivity(uber, 234,
                    UberVoice.createInCallIntent(), 0);
    builder.setContentIntent(inCallPendingIntent);

    builder.setContentText(body);
    builder.setUsesChronometer(false);

    builder.setContentTitle(title);

    builder.setCategory(Notification.CATEGORY_CALL);
    builder.setVisibility(Notification.VISIBILITY_PUBLIC);

    builder.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_RINGTONE), AudioManager.STREAM_RING);
    builder.setVibrate(new long[]{500, 500, 500, 500, 500, 500, 500, 500, 500, 500, 500, 500, 500, 500});

    builder.setPriority(Notification.PRIORITY_MAX);
    builder.setTicker(title);
    builder.setFullScreenIntent(inCallPendingIntent, true);

    builder.addAction(R.drawable.hangup_action, "Reject", CallService.getPendingIntent(uber, callJson, CallService.REJECT));
    builder.addAction(R.drawable.answer_action, "Answer", CallService.getPendingIntent(uber, callJson, CallService.ANSWER));

    NotificationManager notificationManager = (NotificationManager) uber.getSystemService(Context.NOTIFICATION_SERVICE);
    Notification notification = builder.build();
    notificationManager.notify(INCOMING_CALL_NOTIFICATION_ID, notification);

这是creatCallIntent代码:

我注意到我的一些用户正在获得此异常.我不知道如何重现它,我只有关于Crashlytics的报告.似乎深入Google的代码.在使用此代码的数千人中,只有39人有例外.

知道什么可能是错的吗？

谢谢.

我研究了这个,发现它addAction (int icon, CharSequence title, PendingIntent intent)已被弃用,所以我用过addAction (Notification.Action action).在这两种情况下,都无法看到图标.

NotificationCompat.Action action = new NotificationCompat.Action.Builder(R.drawable.ic_share, "", pendingIntent).build();

notificationBuilder.addAction(action);

文本似乎工作,但我把它留空了,因此在主图像下面有一个空的空间,其中应该显示图标

我们的应用程序现在有 targetSdkVersion 26 ( Android 8 ) 并且应用程序使用 FCM 推送通知。当应用程序处于前台状态时，推送通知运行良好。当应用程序不在前台状态时单击通知时会出现此问题。我刚刚在清单中添加了元数据，但仍然出现相同的错误。
