My app uses geofences to notify the user when the enter a location, a notification gets displayed when the user enters the location. what im trying to to is get the triggering geofences convert them to a string, then send them to another activity so that they can be displayed in a list view. Ive watched tutorials online on how to makes list views and how to send data using intents but what im trying to do just doesn't seem to work.
EDIT I'm starting the list view PageActivity using a intent with startActivity from another class the MainActivity.
Goals
If the user clicks on the notification from anywhere especially from outside the application it will open the app with the list view being filled with the geofence details. If the user opens the app just opens the app the from the launcher, then the same to happen. The list to be filled with any geofences that were triggered.

Any Help would be Greatly Appreciated, Thank you.
You have to change this :
Intent i = new Intent(this, listPageActivty.class);
i.putExtra("intentKey",geofenceTransitionDetails);
to this :
Intent i = new Intent(this, listPageActivty.class);
i.putExtra("intentKey",geofenceTransitionDetails);
this.startActivity(i);
I think you just left the startActivity()
And in the other Activity you get the value like this :
String GeoTransitionDetails = getIntent().getExtras().getString("intentKey");
