- 2. Developing Glass Apps Using GDK (XE12 Update) Follow me @chuazy About myself Chua Zi Yong Developing Android for about 5 years Founder of Stream Media Founder of CodeAndroid Singapore https://www.facebook.com/groups/codeandroid/
- 3. Developing Glass Apps Using GDK (XE12 Update) Follow me @chuazy What we will cover today on Glass Introduction Framework Constraints and Possibility Resources This session will cover more on high level development consideration – less emphasis on design and technical discussions
- 4. Developing Glass Apps Using GDK (XE12 Update) Follow me @chuazy Basics of Google Glass What is Glass? Introduction Framework How to use Glass? Constraints and Possibility Resources
- 5. Developing Glass Apps Using GDK (XE12 Update) Follow me @chuazy Getting Started: https://developers.google.com/glass/ 1) Take note of the design principles (very small screen!) 2) Choose your poison: Mirror API or GDK 3) Check out the samples and demos Introduction Framework Constraints and Possibility Resources
- 6. Developing Glass Apps Using GDK (XE12 Update) Follow me @chuazy Developing with GDK 1) Run from Glass itself (offline!) unlike Mirror API 2) Based on Android 4.0.2, apps compiled as APK 3) Download using ADT (GDK Sneak Peak) Introduction Framework Constraints and Possibility Resources
- 7. Developing Glass Apps Using GDK (XE12 Update) Follow me @chuazy How is GDK related to Android development? You can port your Android code and redesign the interface for Glass, supposedly - At this stage, not everything works, e.g. Play Services, default Share API Introduction Framework Constraints and Possibility Resources
- 8. Developing Glass Apps Using GDK (XE12 Update) Follow me @chuazy How is your app triggered? - Command line (that’s how it was done in XE11) - Voice trigger Introduction Framework Constraints and Possibility Resources
- 9. Developing Glass Apps Using GDK (XE12 Update) Follow me @chuazy Voice trigger - Voice trigger is used to launch your app - You can use any commands during development - Glassware only support standard set of voice commands (https://developers.google.com/glass/develop/gdk/input/voice) - You can submit new commands for approval (which you will hear back in around 2 weeks) Introduction Framework Constraints and Possibility Resources
- 10. Developing Glass Apps Using GDK (XE12 Update) Follow me @chuazy Contextual voice commands - Sometimes, voice commands is more than “Take a Picture” - Add voice prompt in voicetrigger.xml (“Ok glass, get directions to, home”) <?xml version="1.0" encoding="utf-8"?> <trigger keyword="@string/glass_voice_trigger"> <input prompt="@string/glass_voice_prompt" /> </trigger> Introduction Framework Constraints and Possibility Resources
- 11. Developing Glass Apps Using GDK (XE12 Update) Follow me @chuazy 3 types of interfaces Introduction Framework Constraints and Possibility Resources
- 12. Developing Glass Apps Using GDK (XE12 Update) Follow me @chuazy Static Cards – appear to the right of Timeline Static cards Right now it does nothing except “show you something” - Please help upvote issue 320 https://code.google.com/p/google-glass-api/issues/detail?id=320 Introduction Framework Constraints and Possibility Resources
- 13. Developing Glass Apps Using GDK (XE12 Update) Follow me @chuazy Live Cards – appear to the left of Timeline - “live” interaction and card can update itself - User can interact with other cards while active Live cards Introduction Framework Constraints and Possibility Resources
- 14. Developing Glass Apps Using GDK (XE12 Update) Follow me @chuazy Immersions – takes over the whole screen - Like a normal Android app - Outside of Timeline - User cannot interact with cards unless they close your app Introduction Framework Constraints and Possibility Resources
- 15. Developing Glass Apps Using GDK (XE12 Update) Follow me @chuazy How to use the Interfaces - Immersion – standard Android app architecture - Static Card – use TimelineManager from either running app or service (insert, update, query, delete) - Live Card – will talk more next slide Introduction Framework Constraints and Possibility Resources
- 16. Developing Glass Apps Using GDK (XE12 Update) Follow me @chuazy Live Card Architecture - Unlike an app, your default launch is a Live Card Service - Keeps on running - Need to create pendingintent to launch menu activity to close the live card - 2 types of rendering – Low and Hi Frequency Introduction Framework Constraints and Possibility Resources
- 17. Developing Glass Apps Using GDK (XE12 Update) Follow me @chuazy Live Card Architecture – Low Frequency Rendering - Small set of views and low update rate - For example, match score User says “Ok Glass, <trigger> Launch live card service Remote View Introduction Framework Constraints and Possibility Resources Live Card
- 18. Developing Glass Apps Using GDK (XE12 Update) Follow me @chuazy Live Card Architecture – High Frequency Rendering - Dynamic rendering - For example, timer User says “Ok Glass, <trigger> Launch live card service Drawing Logic, other services Introduction Framework Constraints and Possibility Resources SurfaceView Live Card
- 19. Developing Glass Apps Using GDK (XE12 Update) Follow me @chuazy Other things to take note of - You can specify touch gestures (like a D-Pad) - Sensors: Voice Input, GPS, Accelerometer,, Camera - Glass heats up very fast and have low battery life - Design your app to be as light weight as possible to reduce load - Continuous video recording is about 45-60 minutes Introduction Framework Constraints and Possibility Resources
- 20. Developing Glass Apps Using GDK (XE12 Update) Follow me @chuazy See some code? Introduction Framework Constraints and Possibility Resources
- 21. Developing Glass Apps Using GDK (XE12 Update) Follow me @chuazy What is available by default - Google Search - Call/SMS/Hangout - Get Directions/POI Searches - Take Picture/Video - Google Music - Gmail - Google Now …. Introduction Framework Constraints and Possibility Resources
- 22. Developing Glass Apps Using GDK (XE12 Update) Follow me @chuazy What interesting apps developers are building - Wolframalpha - “OK Glass, Compute, Population of Finland” Introduction Framework Constraints and Possibility Resources
- 23. Developing Glass Apps Using GDK (XE12 Update) Follow me @chuazy What interesting apps developers are building - DriveSafe – Detects if you are dozing while driving and give directions to nearest rest area Introduction Framework Constraints and Possibility Resources
- 24. Developing Glass Apps Using GDK (XE12 Update) Follow me @chuazy What interesting apps developers are building - WeMoGlass – Control Belkin WeMo devices at home Introduction Framework Constraints and Possibility Resources
- 25. Developing Glass Apps Using GDK (XE12 Update) Follow me @chuazy What limits developers right now? - Band-Aid everywhere – check issues often on the project page, may take time to fix - E.g. mediascanner only works on reboot, share not working, no GCM - Certain features are Mirror API only, notification, action for static cards - No emulator Introduction Framework Constraints and Possibility Resources
- 26.
