37. message types
38. notification • Max Size of 2KB • User defined title / message • Creates item in system tray • Actionable
39. data • Max Size of 4KB • Ideal to trigger events / sync commands • Invisibly sent to app
40. notification + data
41. device / topic / segment
42. TOPICS FirebaseMessaging m = FirebaseMessaging.getInstance(); m.subscribeToTopic("myTopic"); m.unsubscribeFromTopic("myTopic");
43. TOPICS FirebaseMessaging m = FirebaseMessaging.getInstance(); m.subscribeToTopic("myTopic"); m.unsubscribeFromTopic("myTopic");
44. priority levels
45. normal • Perfect for non-time sensitive apps like Email • Does not open network connections on sleeping phones • Conserves battery
46. high • Perfect for apps that need immediate interaction from user - chat / voice alerts etc • Wakes device and opens network connections • Drains a bit more battery
