Identify if an activity was opened from FCM notification click

Question

I am using the fcm console to send messages to all of devices that have my app installed, the notifications don\'t have any extra payload only the notification message.

Answer 1

if you want to Start any Activity without extending FireBaseMessaging class then you can set this flags with your FCM data payload.

So whenever the user clicked on FCM Notification on System Tray.That defined Activity should open.And if you want to get extra bundle data.you can get it using getIntent().getExtras(); method.

    "message":{
     "token":"bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
     "notification":{
       "title":"Match update",
       "body":"Arsenal goal in added time, score is now 3-0"
     },
"android":{
           "ttl":"86400s",
           "notification"{
             "click_action":"MainActivity.class" // define your activity here
           }
         },
 "payload": {
         "aps": {
           "category": "NEW_MESSAGE_CATEGORY"
         }
       }
     }
