Glass w/o Glass: Developing native Glass applications without the hardware with Mike DiGiovanni

GLASS WITHOUT GLASS Developing native Glass applications without the hardware
description
Presented at SCREENS 2013 in Toronto. Details at fitc.ca/screens There are about 10,000 Google Glass devices in the wild, but only a fraction of those are in the hands of developers. 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.

About Mike DiGiovanni Mobile developer Why me?
Native Glassware Leader○ Winky○ Launchy○ Bulletproof○ GlassAuth○ Research into audio and sensor APIs
Participated in original Glass hackathonExtensive Android experienceWearables Gold Rush
A short look at Glass
Why native?
Low latency Control over the user experience Keep data away from Google
Pre-requisites
Android SDK - http://developer.android.com/sdk/ Good understanding of Android development
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
Emulator Setup
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
Themes
Touch management – Stop Watch
Touchpad on the side Translate to keystrokes
tab, dpad left – swipe backwardshift+tab, dpad right – swipe forwardback – swipe downdpad center - tap
Generic Motion Events
Sensors - Compass
Not the greatest Typical
registration Typical events
More sensors - Level
Can be used to balance it on your head straight
Gaming functions Typical registration Typical events
Location – Sugar Glider
Short confusing history NOW Standard location
provider registration and listening
Need maps?
Audio Recording – Wave form
Mono AudioSource mic AudioRecord
class
What APIs don’t work
Location API Voice Recognition Face detection Google APIs (Maps, +, Play Store)
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
Comparison app on Device vs Glass
LIVE DEMO!
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?
Ideas
Second screen for gaming – HUD, Hidden info Pro camera Viewfinder for wifi cameras Presentation helper Think business specific Assistive devices
