Question

我有一个Android应用程序，正在其中尝试实现Firebase推送通知。我在firebase控制台中正确安装了项目，并下载并找到了json文件。我的通知代码如下。

public class MyFirebaseMessagingService extends FirebaseMessagingService {
    public static final int MESSAGE_NOTIFICATION_ID = 6545;

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        RemoteMessage.Notification notification = remoteMessage.getNotification();
        assert notification != null;
        String notificaitonTitle = "";
        Map data = null;

        try {
            data = remoteMessage.getData();
            notificaitonTitle = data.get("title").toString();
        } catch (Exception e) {
            e.printStackTrace();
        }

        if (remoteMessage.getData().size() > 0) {
            assert data != null;
            createNotification(notificaitonTitle, data.get("desc").toString());
        }

    }

    private void createNotification(String notificationTitle, String desc) {
        Context context = getBaseContext();

        Intent intent = new Intent(this, SplashActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
                PendingIntent.FLAG_ONE_SHOT);

        String CHANNEL_ID = "channel_01";
        String CHANNEL_NAME = "channel_01";
        int sound_notification = context.getSharedPreferences("setting", MODE_PRIVATE).getInt("sound_notification", 1);
        Uri soundTest = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://" + context.getPackageName() + "/raw/sound" + (sound_notification));

        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
            int notifyID = 1;

            int importance = NotificationManager.IMPORTANCE_HIGH;

            Notification notification =
                    new NotificationCompat.Builder(this)
                            .setSmallIcon(R.drawable.ic_launcher)
                            .setContentTitle(notificationTitle)
                            .setContentIntent(pendingIntent)
                            .setAutoCancel(true)
                            .setChannelId(CHANNEL_ID)
                            .setSound(soundTest)
                            .build();
            NotificationChannel mChannel = new NotificationChannel(CHANNEL_ID, CHANNEL_NAME, importance);

            NotificationManager mNotificationManager =
                    (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

            if (mNotificationManager != null) {
                mNotificationManager.createNotificationChannel(mChannel);
                mNotificationManager.notify(notifyID, notification);
                }


            } 
        else {
                 NotificationCompat.Builder notificationBuilder =
                    new NotificationCompat.Builder(this, CHANNEL_ID);
                     notificationBuilder
                    .setSmallIcon(R.drawable.ic_launcher).setContentTitle(notificationTitle)
                    .setSound(soundTest)
                    .setAutoCancel(true)
                    .setContentIntent(pendingIntent);


            NotificationManager mNotificationManager = (NotificationManager) context
                    .getSystemService(Context.NOTIFICATION_SERVICE);
            if (mNotificationManager != null) {
                mNotificationManager.notify(MESSAGE_NOTIFICATION_ID, notificationBuilder.build());
            }
        }

    }
}

我的构建工具和目标如下所示

compileSdkVersion 27
buildToolsVersion "27.0.3"

我在我的项目中实现了如下所示的firebase库。

implementation 'com.google.firebase:firebase-messaging:17.1.0'
implementation 'com.google.firebase:firebase-core:16.0.1'

让我知道是否有人可以建议我我的代码有什么问题。我从最近四个小时开始尝试，但找不到合适的解决方案。

谢谢
