android - FCM 推送通知在某些设备上不起作用

Question

我们使用 FCM 创建了一个带有通知的聊天应用程序我的代码是正确的我的设备也正在获取推送通知数据但是一些中国制造的设备如 vivo、oppo、一加、小米不允许显示通知，除非我在各自制造商的 protected 应用程序列表中添加应用程序。是他们对此的任何解决方案。

private NotificationManagerCompat notificationManager;

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);

    Log.d("test","call");

    notificationManager = NotificationManagerCompat.from(this);
    sendNotification(remoteMessage.getNotification().getTitle(), remoteMessage.getNotification().getBody());
}

private void sendNotification(String title, String msg) {
    Intent resultIntent = new Intent(this, ActivitySplashScreen.class);

    String channelId = getString(R.string.chc);
    String channelName = "Message Notification";

    TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
    stackBuilder.addNextIntentWithParentStack(resultIntent);

    PendingIntent pendingIntent = stackBuilder.getPendingIntent(99, PendingIntent.FLAG_UPDATE_CURRENT);

    Notification notification = new NotificationCompat.Builder(this, channelId)
            .setSmallIcon(R.mipmap.ic_launcher_round)
            .setContentTitle(title)
            .setContentText(msg)
            .setPriority(NotificationCompat.PRIORITY_HIGH)
            .setCategory(NotificationCompat.CATEGORY_MESSAGE)
            .setContentIntent(pendingIntent)
            .build();

    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
        NotificationManager manager = getSystemService(NotificationManager.class);
        NotificationChannel channel = new NotificationChannel(channelId, channelName, NotificationManager.IMPORTANCE_HIGH);
        manager.createNotificationChannel(channel);
    }

    notificationManager.notify(10, notification);
}

Answer 1

我可以确认此实现适用于 One Plus 和小米设备(我们有大量用户通过这些设备使用我们的应用程序，并且他们没有因 FCM 通知而产生崩溃或问题)。

无法确认 Vivo 或 Oppo 的任何信息(到目前为止，我们确实知道我们没有用户使用此类设备)。

最重要的是，无论应用程序是在前台还是在后台，通知功能都能很好地实现。如果有人想对此事进行放大，this article用简单的方式解释它。

现在，我在 Android 中用于 FCM 实现的代码:

//我的消息服务

public class MyFirebaseMessagingService extends FirebaseMessagingService {

  public static final String TAG = "Firebase Msg";

  @Override
  public void onMessageReceived(RemoteMessage remoteMessage) {
    Map<String, String> data = remoteMessage.getData();
    final LocalNotification localNotification = new LocalNotification();
    //data --> entityId - entityType - pushNotificationType
    // Check if message contains a data payload.
    if (data.size() > 0) {
        localNotification.setEntityId(data.get("entityId"));
        localNotification.setEntityType(data.get("entityType"));
        localNotification.setPushNotificationType(data.get("pushNotificationType"));
        localNotification.setTitle(data.get("title"));
        localNotification.setBody(data.get("body"));
        localNotification.setIcon(data.get("icon"));
        localNotification.setDate(new Date().getTime());
        localNotification.setRead(false);
    }

    if (localNotification.getEntityId() != null) {
        LocalNotification notificationRetrieved = FirebaseNotificationsHelper.insertLocalNotification(localNotification);
        FirebaseNotificationsHelper.createNotificationInStatus(notificationRetrieved);
    }
  }
}

//创建通知状态

static void createNotificationInStatus(LocalNotification localNotification) {

    String notificationChannelId = App.getContext().getString(R.string.default_notification_channel_id);
    String notificationChannelName = App.getContext().getString(R.string.default_notification_channel_name);
    String notificationChannelDescription = App.getContext().getString(R.string.default_notification_channel_description);

    NotificationCompat.Builder notificationBuilder;
    NotificationCompat.Builder notificationBuilderPublicVersion;

    notificationBuilder = new NotificationCompat.Builder(App.getContext(), notificationChannelId);
    notificationBuilderPublicVersion = new NotificationCompat.Builder(App.getContext(), notificationChannelId);

    notificationBuilder.setDefaults(NotificationCompat.DEFAULT_VIBRATE | NotificationCompat.DEFAULT_LIGHTS | NotificationCompat.DEFAULT_SOUND)
            .setWhen(System.currentTimeMillis())
            .setSmallIcon(R.drawable.ic_stat_push_notif)
            .setTicker(localNotification.getTitle())
            .setPriority(NotificationCompat.PRIORITY_HIGH)
            .setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
            .setContentTitle(localNotification.getTitle())
            .setContentText(localNotification.getBody())
            .setStyle(new NotificationCompat.BigTextStyle().bigText(localNotification.getBody()))
            .setPublicVersion(notificationBuilderPublicVersion.setSmallIcon(R.drawable.ic_stat_push_notif).setContentTitle(localNotification.getTitle()).
                    setWhen(System.currentTimeMillis()).setContentText(localNotification.getBody()).build())
            .setGroup(NOTIFICATION_GROUP)
            .setVibrate(new long[]{1000, 1000, 1000, 1000, 1000})
            .setAutoCancel(true);

    int notificationId = SharedPreferencesUtils.getInstance(App.getContext()).getIntValue(PREF_KEY_NOTIFICATION_ID, 0);

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        NotificationManager notificationManager = (NotificationManager) App.getContext().getSystemService(Context.NOTIFICATION_SERVICE);
        NotificationChannel notificationChannel = new NotificationChannel(notificationChannelId, notificationChannelName, NotificationManager.IMPORTANCE_HIGH);
        // Configure the notification channel.
        notificationChannel.setDescription(notificationChannelDescription);
        notificationChannel.enableLights(true);
        notificationChannel.setLightColor(Color.RED);
        notificationChannel.setVibrationPattern(new long[]{0, 1000, 500, 1000});
        notificationChannel.enableVibration(true);
        notificationChannel.setLockscreenVisibility(NotificationCompat.VISIBILITY_PUBLIC);
        notificationChannel.setImportance(NotificationManager.IMPORTANCE_HIGH);
        notificationManager.createNotificationChannel(notificationChannel);
        notificationManager.notify(notificationId, notificationBuilder.build());
    } else {
        /* Kitkat and previous versions don't show notifications using NotificationManagerCompat */
        if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.KITKAT) {
            NotificationManager notificationManager = (NotificationManager) App.getContext().getSystemService(Context.NOTIFICATION_SERVICE);
            notificationManager.notify(notificationId, notificationBuilder.build());
        } else {
            NotificationManagerCompat notificationManager = NotificationManagerCompat.from(App.getContext());
            notificationManager.notify(notificationId, notificationBuilder.build());
        }
    }
    notificationId++;
    SharedPreferencesUtils.getInstance(App.getContext()).setValue(PREF_KEY_NOTIFICATION_ID, notificationId);
}
