FCM：当应用程序处于前台状态时处理其应用程序的不同数据通知

Question

I am sending 2 different data notifications in my app using cloud functions.

when I received the 1st notification in app and taps on notification it redirects to the my intended page using pendingIntent.

Now when I received the 2nd notification in app and taps on notification how to redirects to another activity(sent Invitation page). How to implement this .

    }

Answer 1

here is the simple snippet use a flag in the notification you push from the server.

when you receive notification in onMessageRecevied function extract that flag and pass it to sendNotification

    private void sendNotification(int flag, String title,String messageBody ) {
NotificationManager    mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    long notificatioId = System.currentTimeMillis();


Intent intent=null;
   if(flag==1){
        intent = new Intent(getApplicationContext(), activity1.class);
   }
   else{
         intent = new Intent(getApplicationContext(), activity2.class);
   }

    intent.putExtra("fromItem",false);
    intent.putExtra("title", title);; // Here pass your activity where you want to redirect.

    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
    PendingIntent contentIntent = PendingIntent.getActivity(this, (int) (Math.random() * 100), intent, 0);

    int currentapiVersion = android.os.Build.VERSION.SDK_INT;
    if (currentapiVersion >= android.os.Build.VERSION_CODES.LOLLIPOP){
        currentapiVersion = R.mipmap.ic_launcher;
    } else{
        currentapiVersion = R.mipmap.ic_launcher;
    }

    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
            .setSmallIcon(currentapiVersion)
            .setContentTitle(this.getResources().getString(R.string.app_name))
            .setStyle(new NotificationCompat.BigTextStyle().bigText(messageBody))
            .setContentText(title)
            .setAutoCancel(true)
            .setPriority(Notification.PRIORITY_HIGH)
            .setDefaults(Notification.FLAG_AUTO_CANCEL | Notification.DEFAULT_LIGHTS | Notification.DEFAULT_VIBRATE | Notification.DEFAULT_SOUND)
            .setContentIntent(contentIntent);
    mNotificationManager.notify((int) notificatioId, notificationBuilder.build());
}

In the server side code add the flag in the JSON message

 var data = new
            {

                to=deviceId,
                    notification = new
                    {
                        body = "\""+notificationMessage +"\"",
                        title = "\""+_title+"\"",
                        sound = "Enabled\""
                    }
                    ,
                    data=new {

                        flag= "\"" + _flag+"\"",
                        message= "\""+notificationMessage+"\"",
                        additional = "\"" + addtional+"\""

                    }




            };

this is the simple snippet for json packet

Answer 2

You can't predefined it in NotificationBuilder , but you can do one thing you can create one common activity and route all notifications to this activity with some flag/type to recognise the notification type. From this activity you can redirect to your desired activity by checking the notification type you passed.

Answer 3

Inside this function, change Intent according to messageBody,

private void createNotification(String messageBody, String FirstName, String amount,String docId) {

    Intent intent=null;
    if(messageBody.contains(“xyz”))
            intent = new Intent( this, ReceivedNotification.class );
    else
            intent = new Intent( this, SecondReceivedNotification.class );

    — — —

    PendingIntent resultIntent = PendingIntent.getActivity( this , 0, intent,
            PendingIntent.FLAG_UPDATE_CURRENT);
}

and pass it over to Pending Intent.
