使用 FCM 的 Android 通知

Question

当应用程序被终止时，我遇到通知中的数据问题，数据从意图发送的数据将变为空，否则如果应用程序运行时我能够看到数据。

    Intent intent = new Intent(getApplicationContext(), SplashActivity.class);
//you can use your launcher Activity insted of SplashActivity, But if the Activity you used here is not launcher Activty than its not work when App is in background.
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
//Add Any key-value to pass extras to intent
        intent.putExtra("pushnotification", "yes");
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);

        Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationManager mNotifyManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
//For Android Version Orio and greater than orio.
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
            int importance = NotificationManager.IMPORTANCE_LOW;
            NotificationChannel mChannel = new NotificationChannel("Sesame", "Sesame", importance);
            mChannel.setDescription(messageBody);
            mChannel.enableLights(true);
            mChannel.setLightColor(Color.RED);
            mChannel.enableVibration(true);
            mChannel.setVibrationPattern(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});

            mNotifyManager.createNotificationChannel(mChannel);
        }
//For Android Version lower than oreo.
        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this, "Seasame");
        mBuilder.setContentTitle(title)
                .setContentText(messageBody)
                .setSmallIcon(R.mipmap.ic_custom_notification)
                .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher))
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setColor(Color.parseColor("#FFD600"))
                .setContentIntent(pendingIntent)
                .setChannelId("Sesame")
                .setPriority(NotificationCompat.PRIORITY_LOW);

        mNotifyManager.notify(getRandomId(), mBuilder.build());

像这样更改您的请求正文：

{ 
"data":{
    "title" : "your_title",
    "body" : "your_body" 
}, 
  "to": "device_token",
  "priority": "high" 
}

和 onMessageReceived：

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    if (remoteMessage.getData().size() > 0) {
        Log.d(TAG, "Message data payload: " + remoteMessage.getData());

        String title = remoteMessage.getData().get("title");
        String body = remoteMessage.getData().get("body");
        sendNotification(title,body); // edit for your self
    }
}

现在它在应用程序被杀死，背景和前景时起作用
