1. Developer Day

2. All About Push
Thomas Bouldin
Software Engineer, Parse

3. How BIG is Your App?
Think outside the 4” box
The cloud has no home button
DAU are like butterflies
Focus on engaging moments
Your App Here

4. The Power of Parse Push
Easy to get started*
Parse Powered
Cross platform
Scale without skipping a beat
Keep it simple or turn it up to 11
*We couldn’t Parse-ify 3rd party services, but we have guides for them

5. Push 101: Hello, World!
Cast a wide net for broadly-applicable notifications
Simple setup, all code available in quick start guides
Create pushes visually

6. Push 101: Hello, World!
Setting up Android Push
PushService.subscribe(this, "", MyActivity.class);
PushService.setDefaultPushCallback(this, MyActivity.class);

7. DEMO: iOS “Hello, World!”

8. Push 201: Advanced Targeting
Focused messages for selective audiences
Pro features of WYSIWYG push console
Target by arbitrary features
Scheduled pushes

9. Push 201: Advanced Targeting
Demystifying SubscribeAsync
// Actual code from Parse’s .NET implementation of ParsePush
public static Task SubscribeAsync(IEnumerable<string> channels,
CancellationToken cancellationToken) {
var installation = ParseInstallation.CurrentInstallation;
installation.AddRangeUniqueToList("channels", channels);
return installation.SaveAsync(cancellationToken);
}

10. Push 201: Advanced Targeting
The Current Installation
Installations are Parse Objects
The Current Installation is your app on this phone
Save any data you wish
Automatic feature tracking
Can create queries for them*

11. DEMO: Advanced Targeting

12. Push 301: Push from Code
Push for life (and code) hackers
Automate everything
Send more precise info to fewer people
Break platform boundaries
Push from Cloud Code

13. Push 301: Push from Code
Pushing to Everyone
// Send “Hello, World!” to everyone
await ParsePush.SendAlertAsync("Hello, World!");

14. Push 301: Push from Code
Using Advanced Targeting
// Invite all iOS users who are over 21 to get an Apple-Tini
await ParsePush.SendAlertAsync(
"Windows fan to Apple fan, let’s grab a drink",
from installation in ParseInstallation.Query
where installation.DeviceType == "ios"
where installation.Get<int>("age") > 21
select installation
);

15. Push 401: Psychic Apps
Push as an RPC
Cheaper and faster than polling
Don’t be a drag to refresh
Draw them in or light up

16. Wrap Up
Think big and build an app that never sleeps
Use this bigness for good
Get started with our Push Quickstart Guide
Push to channels for easy but powerful setup
Advanced targeting for dynamic flexibility
Automate frequent pushes
Automatically update when new info is discovered
