MIUI上无声推送通知

MIUI上无声推送通知

11

我的应用程序的主要功能是从远程服务器发送推送通知消息。我正在使用 FCM 作为消息传递服务。但是，在小米 Mi 9 Lite（Android 9/MIUI 11）上，通知没有任何声音。然而，在小米红米 Note 5（Android 9/MIUI 10）上声音正常工作，在三星 Galaxy S7 Edge（Android 8）上也一样。根据文档，我创建了扩展 FirebaseMessagingService 的 MessagingService 和通知频道。

这是我的代码：

public class MessagingService extends FirebaseMessagingService {

    private static String channelId;
    private NotificationManager notificationManager;
    private NotificationChannel notificationChannel;
    private NotificationCompat.Builder notificationBuilder;

    private MessagesViewModel viewModel;

    public MessagingService() { }

    @Override
    public void onCreate() {
        super.onCreate();
        channelId = getResources().getString(R.string.default_notification_channel_id);
        notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);

        final Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

        notificationBuilder = new NotificationCompat.Builder(this, channelId);
        notificationBuilder.setSmallIcon(R.raw.metrial_message_icon);
        notificationBuilder.setAutoCancel(false);
        notificationBuilder.setSound(soundUri);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            final AudioAttributes audioAttributes = new AudioAttributes.Builder()
                    .setUsage(AudioAttributes.USAGE_NOTIFICATION)
                    .build();

            String name = getString(R.string.channel_name);
            String description = getString(R.string.channel_description);
            int importance = NotificationManager.IMPORTANCE_HIGH;
            notificationChannel = new NotificationChannel(channelId, name, importance);
            notificationChannel.setDescription(description);
            notificationChannel.enableLights(true);
            notificationChannel.setShowBadge(true);
            notificationChannel.setSound(soundUri, audioAttributes);
            notificationManager.createNotificationChannel(notificationChannel);
            notificationBuilder.setChannelId(channelId);
        }
        else {
            notificationBuilder.setPriority(NotificationCompat.PRIORITY_HIGH);
            notificationBuilder.setBadgeIconType(NotificationCompat.BADGE_ICON_SMALL);
            notificationBuilder.setLights(Color.WHITE, 500, 5000);
        }

        viewModel = new MessagesViewModel(getApplication());
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
    }

    @Override
    public void onNewToken(@NonNull String s) {
        super.onNewToken(s);
        logger.info("onNewToken()");
        ConnectionParameters.getInstance().setToken(s);
        MyPrefs.getInstance(getApplicationContext()).putString(Constants.TOKEN, s);
    }

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

        final String messageId = remoteMessage.getData().get("message_id");
        final String title = remoteMessage.getData().get("title");
        final String body = remoteMessage.getData().get("body");

        if (messageId != null && title != null && body != null) {

            final Message message = new Message();
            message.setMessageId(messageId);
            message.setTitle(title);
            message.setContent(body);
            message.setTimestamp(new Date());

            try {
                message.setNotificationId((int)viewModel.insert(message));
            } catch (ExecutionException | InterruptedException e) {
                e.printStackTrace();
            }

            logger.info("onMessageReceived(): notificationId=" + message);

            if (MyPrefs.getInstance(getApplicationContext()).getBoolean(Constants.ENABLE_PUSH)) {
                notificationBuilder.setContentTitle(title);
                notificationBuilder.setContentText(body);

                final Intent notifyIntent = new Intent(this, MessageInfoActivity.class);
                notifyIntent.putExtra(Constants.ARG_MESSAGE_OBJECT, message);
                TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
                stackBuilder.addNextIntentWithParentStack(notifyIntent);
                PendingIntent pendingActivityIntent =
                        stackBuilder.getPendingIntent(message.getNotificationId(), PendingIntent.FLAG_UPDATE_CURRENT);
                notificationBuilder.setContentIntent(pendingActivityIntent);

                final Notification notification = notificationBuilder.build();
                notification.defaults = Notification.DEFAULT_SOUND|Notification.DEFAULT_LIGHTS;
                notificationManager.notify(message.getNotificationId(), notification);
            }
        }
    }

    private final Logger logger = LoggerFactory.getLogger(getClass());
}

在“设置->通知”中，我有以下参数：

。在我的“推送通知通道”内，声音是启用的，但每当有一条消息时，似乎应用程序通知设置会覆盖通知通道中的参数。

。希望有解决方法，因为在流行的应用程序（如WhatsApp、Telegram等）中，这些开关在安装后是默认启用的。希望有人能帮助！

由于没有提供更好的解决方案，我猜测在MIUI（以及大多数其他中国OEM厂商）上无法通过编程方式允许声音/徽章计数器/浮动通知。手动打开这些设置是用户的特权。因此，为了增强用户体验，尽可能减少“点击”数量非常重要。因此，我们可以提供一个对话框，描述如何启用上述功能，并提供指向应用程序设置的按钮。即要通过Intent打开通知设置页面，请执行以下操作：

final Intent notificationSettingsIntent = new Intent();
notificationSettingsIntent
        .setAction("android.settings.APP_NOTIFICATION_SETTINGS");
notificationSettingsIntent
        .setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    notificationSettingsIntent.putExtra(
            "android.provider.extra.APP_PACKAGE",
            activity.getPackageName());
}
else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        notificationSettingsIntent.putExtra(
                "app_package",
                activity.getPackageName());
        notificationSettingsIntent.putExtra(
                "app_uid", 
                activity.getApplicationInfo().uid);
}
activity.startActivityForResult(
        notificationSettingsIntent, 
        NOTIFICATIONS_SETTINGS_REQUEST_CODE);

你可以通过点击“打开通知设置”按钮来打开对话框，点击此按钮将触发上面的代码片段。
