Google Glass? What is that?

GDK - Glass Development Kit, is very similar to building android apps. This apps run directly on Glass.Mirror API - Is just a series of web services that are delivered to the device as HTML cards. This does not require to install anything on the device.You can communicate with the mirror API using your language of choice.Currently available:● Go● Java● .Net● PHP● Python● Ruby

Mirror API or GDK?

How does the Mirror API work?

Source code and instructions are here:

https://developers.google.com/glass/develop/mirror/quickstart/index

How do I get started?

Mirror API apps do not get deploy on the Glass device. The app should leave on a webserver and communicate to the Glasses via the API.

I deployed my “hello world” app to Heroku. All I had to do is make a few changes to the Maven POM file to generate the war file.

Three simple commands:● mvn package● mvn war:war● heroku deploy:war --war target/[appName].war --app appName

Where can I deploy this app?

Google Playground:https://developers.google.com/glass/tools-downloads/playground?hl=en

Q: Can you test all features?A: Not really but enough to get started.

● You can test how your HTML cards look● You cannot reply● Does not support bundles

But how do I test without glasses?

Not much :)

It’s the “Quick Start” plus some basic functionality I added to test my own webservice.

DEMO

So what does your app do?

index.jsp

MainServlet.java

Can we see some code now?

But where is your code?

Can we see it now on Glass?

Sure, find this guy ->
