2. Proprietary + Confidential Proprietary + Confidential Proprietary + Confidential Agenda History & Background Nearby.Messages Nearby.Notifications Nearby.Connections
3. Proprietary + Confidential Proprietary + Confidential Proprietary + Confidential History & Background
5. What Technology?
6. What Technology?
8. Big Cloud Hashmap for the win! “AE123” “AE123” =
9. A wild usecase appears!
10. Over to you... Nearby Messages API for Android & iOS
11. … and the cool things you build FIND SHARE PLAY
12. Proprietary + Confidential Proprietary + Confidential Proprietary + Confidential Let's (finally) write some code!
13. Publishing a message Nearby.Messages.publish(mClient, new Message(bytes));
14. Subscribing for messages MessageListener listener = new MessageListener() { void onFound(Message m) { byte[] bytes = m.getContent(); } }; Nearby.Messages.subscribe(mClient, listener);
15. Doing cool things with beacons Nearby.Messages: Google's recommended beacon scanning API Easy permissions Free scans Background wakeup
16. Subscribing for beacons in the background private void backgroundSubscribe() { SubscribeOptions options = new SubscribeOptions.Builder() .setStrategy(Strategy.BLE_ONLY) .build(); Nearby.Messages.subscribe(mClient, getPendingIntent(), options); } private PendingIntent getPendingIntent() { return PendingIntent.getBroadcast( this, 0, new Intent(this, BeaconMessageReceiver.class), PendingIntent.FLAG_UPDATE_CURRENT); }
17. Subscribing for beacons in the background private void backgroundSubscribe() { SubscribeOptions options = new SubscribeOptions.Builder() .setStrategy(Strategy.BLE_ONLY) .build(); Nearby.Messages.subscribe(mClient, getPendingIntent(), options); } private PendingIntent getPendingIntent() { return PendingIntent.getBroadcast( this, 0, new Intent(this, BeaconMessageReceiver.class), PendingIntent.FLAG_UPDATE_CURRENT); }
18. Receiving beacon messages @Override public void onReceive(Context context, Intent intent) { Nearby.Messages.handleIntent(intent, new MessageListener() { @Override public void onFound(Message message) { // do something with message.getBytes() } @Override public void onLost(Message message) { // Oh noes! My beacon is out of range. } }); }
19. Advanced beacon features MessageFilter lets you scan for: • PUBLIC namespaced attachments in other namespaces • Raw BLE beacon IDs Special beacon callbacks: • onDistanceChanged • onBleSignalChanged
20. Example: Scan for iBeacons MessageFilter messageFilter = new MessageFilter.Builder() .includeIBeaconIds(PROXIMITY_UUID, major, minor) .build(); SubscribeOptions options = new SubscribeOptions.Builder() .setStrategy(Strategy.BLE_ONLY) .setFilter(messageFilter) .build(); @Override public void onFound(Message message) { IBeaconId ibeacon = IBeaconId.from(message); }
21. Proprietary + Confidential Proprietary + Confidential Proprietary + Confidential Nearby Notifications
22. Notifications about nearby things
23. Notifications about nearby things Attach URLs, or app intents We'll send users to Play Store if app not installed Notifications can be targeted Notifications are a reward for "good behavior", not a guarantee
24. Example: App Attachment { "title": "Get the app!", "url": "intent://host/path#Intent;scheme=scheme;package=com.yourapp.ui;end;", "targeting":[{ "anyOfAppInstallStates": ["NOT_INSTALLED"], "startTimeOfDay": "9:00", "endTimeOfDay": "17:00" }] }
25. Nearby Connections
26. Help! Let us know what you're building Let us know what works & doesn't work Let us know what you'd like to see in the future
