Mike DiGiovanni, creator of Glass apps like Launchy, Winky, and Bulletproof, will guide you through what it takes to create a native Glass app, style it to look Glassy, and get it running on a plain old Android emulator/hardware. You will learn the some of the APIs that work best on Glass, along with a list of APIs to avoid. If the GDK remains unavailable by the time of the presentation, there will be a section on future proofing your software. Mike will be available afterwards to give attendees the opportunity to experience Glass and get some 1-on-1 Q&A time. This is a presentation aimed at beginners to native Glass development. Some Android development experience is a plus.

1. Developing native Glass applications without the hardware

2. About Mike DiGiovanni
 Mobile developer
 Why me?
 Native Glassware Leader
○ Winky
○ Launchy
○ Bulletproof
○ GlassAuth
○ Research into audio and sensor APIs
 Participated in original Glass hackathon
 Extensive Android experience
 Wearables Gold Rush

3. A short look at Glass

4. Why native?
 Low latency
 Control over the user experience
 Keep data away from Google

5. Pre-requisites
 Android SDK - http://developer.android.com/sdk/
 Good understanding of Android development

6. Glassless
 A sample app
 Plain old Android SDK
 Basic sensor usage – Google sample
 Basic interaction usage - Google sample
 Basic TTS
 Example of maps static API and location – Jenny
Murphy of Google
 Examples of menu
 Examples of theming

7. Emulator Setup

8. Menus
 XE7 - Google made a change to the underlying
platform to present menus in a very Glassy way
 Pulls from HDPI bucket
 Mostly white, subtle shading, hard to describe
 70x70 icons

9. Themes

10. Touch management – Stop Watch
 Touchpad on the side
 Translate to keystrokes
 tab, dpad left – swipe backward
 shift+tab, dpad right – swipe forward
 back – swipe down
 dpad center - tap
 Generic Motion Events

11. Sensors - Compass
 Not the greatest
 Typical
registration
 Typical events

12. More sensors - Level
 Can be used to balance it
on your head straight
 Gaming functions
 Typical registration
 Typical events

13. Location – Sugar Glider
 Short confusing history
 NOW Standard location
provider registration
and listening
 Need maps?

14. Audio Recording – Wave form
 Mono
 AudioSource mic
 AudioRecord
class

15. What APIs don’t work
 Location API
 Voice Recognition
 Face detection
 Google APIs (Maps, +, Play Store)

16. Final conversion
 Remove any usage of non hdpi bitmap based
drawables
 Likely that a menu will automatically show up and we
wont have to do a dance
 Evaluate Battery life
 Final GDK

17. LIVE DEMO!

18. Tips
 Screen off = App exit
 Don’t go out of your way
 Evaluate whether it’s really worth going native
 Think inside a timeline
 Make friends in the community
 XE10
 Limit text, limit depth, limit functionality
 How can my company's software for Glass change our
customers lives?
 How can Glass hardware change my company?

19. Ideas
 Second screen for gaming – HUD, Hidden info
 Pro camera
 Viewfinder for wifi cameras
 Presentation helper
 Think business specific
 Assistive devices
