24. GEOFENCE INTENT private PendingIntent getGeofencePendingIntent() { if (mGeofencePendingIntent != null) { return mGeofencePendingIntent; } Intent intent = new Intent(this, GeofenceTransitionsIntentService.class); return PendingIntent.getService(this, 0, intent, PendingIntent.

28. NOT BORING AT ALL…
29. SHOW ME HOW IT WORKS !
30. TESTS ▸ Real testing ▸ Mock location apps ▸ Emulator ▸ Mock location provider
31. LIMITATIONS
32. LIMITATIONS 100 geofences par application et par utilisateur (pour un device)
33. BEST PRACTICES ▸ Réduire l’utilisation de la batterie en changeant la ‘réactivité’ des notifications ▸ Optimiser les rayons de geofences ▸ Surveiller seulement quand c’est nécessaire ▸ Utiliser les transitions DWELL plutôt que ENTER
