for this you have to set a boolean variable in shared preference

for example isActivityOpened = true

set value false when you destroy "TrackinActivity" and set value true in onCreate of this activity

 @Override
 public void onMessageReceived(RemoteMessage remoteMessage) {
        super.onMessageReceived(remoteMessage);
        if(isActivityOpened){//check sharedpreference

           //here send local broadcast message and receive in "TrackinActivity"
           //on receive method of local broadcast update some values in activity

        }else{

           //here start activity as usual 

        }
 }

for getting details about local broadcast
