CODE:

Introductions

  • What are we going to do?

Repo Urls:

Glass aside

  • "timeline"

Goals

  • Consume a REST service
  • Display info on a device
  • More interesting things!

Goals

CODE

CODE

Wear Remote Input

  • Similar to what we've done

More Interesting Things

  • App running on Wear
  • Communication
  • Example

Wear app

  • Wear is its own Android OS
  • App distributed within phone app
  • Uses phone for networking
  • No keyboard!

Device Communication

Phone <=> Watch

  • Data Items
    • Asynchronous
    • Guaranteed
    • Suggested Size limit (~100KB)
      • Circumventable
    • Callbacks to implement
    • State to maintain
  • Messages
    • Synchronous
    • Not Guaranteed
    • Hard Size limit (~100KB)
    • Service to receive messages
    • State to maintain

Important Considerations

  • Be stingy with your network usage
  • Be stingy with your battery usage
    • Network
    • Sensors
    • Display Updates

Help me choose

  • Runs entirely on watch
  • Input is quick and easy
  • Stops itself when it's done
