Previous concepts

Timeline is a carousel of cards which are supposed to be around your head.

New gestures for the touchpad like: One finger: swipe left, swipe right, swipe down and tap Two fingers: swipe left, swipe right and tap Three fingers: tap

Cards are the unit of information in Google Glass. They can be categorized depending on where are the cars in the timeline, and how interactive they are.

New concepts for Google Glass

Live cards appear in the present section of the timeline and display information that is relevant at the current time.

Immersions give you more ways to consume user input and create user interfaces. This allows you to create the most custom experience, but involves the most work.

Static cards appear in the past section of the timeline. They show information as pictures, notes, videos, etc.

Types of Cards for Google Glass

Tools you need to develop apps for Google Glass

Tools to develop apps

GDK The Glass Development Kit (GDK) is an add-on to the Android SDK, that lets you build Glassware that runs directly on Glass.

In general, use the GDK if you need the following features:

The Mirror API

Setting the Developer Environment

Configuring environment Get the Android 4.4.2 (API 19) SDK and Glass Development Kit Preview add-on from the Android SDK Manager

Configuring environment On Glass, turn on USB debugging (Settings > Device Info > Turn on debug)

Configuring environment

In Linux and Mac systems the detection of the glasses are automatic. In Windows systems you must install the driver by your own. In fact, you must modify the driver provided by Google for this system in order to make it work. Besides, to install the driver in a Windows 8 system you must disable the driver signature enforcement feature. The driver is in the folder: ..\sdk\extras\google\usb_driver

Configuring environment Before your system detects the glasses, one message is sent to your glasses. It asks you to confirm whether you trust the computer that your glasses are connected to, or not. Once you confirm. The next step is to check out if your device is accesible, by typing: adb devices

Making a simple helloworld app

Helloworld app

1. Create a new Android project

Helloworld app

2. Set the values for a new project

Helloworld app

3. Uncheck «Create custom launcher icon»

Helloworld app

4. Click next

Helloworld app

5. Click finish

Helloworld app

1. Delete any source code related with Fragment, in the MainActivity.java file 2. Check the android manifest. It must have this line: <uses-permission android:name="com.google.android.glass.permission.DEVELOPMENT" />

Helloworld app 3. Define a trigger for our app: 3.1. Define the trigger: <trigger keyword="@string/glass_voice_trigger" /> <string name="glass_voice_trigger">Hello world</string> 3.2. Declare the trigger in the android manifest for the main activity:

<intent-filter> <action android:name="com.google.android.glass.action.VOICE_TRIGGER" /> </intent-filter>

<meta-data android:name="com.google.android.glass.VoiceTrigger" android:resource="@xml/voice_trigger" />

Helloworld app

4. Define a style.xml for our app: 4.1. Define a new style in styles.xml file: <style name="MenuTheme" parent="@android:style/Theme.DeviceDefault"> <item name="android:windowBackground">@android:color/transparent </item> <item name="android:colorBackgroundCacheHint">@null </item> <item name="android:windowIsTranslucent">true </item> <item name="android:windowAnimationStyle">@null </item> </style> 4.2. Set the style of your activity to the new one: android:theme="@style/MenuTheme"

Helloworld app

5. Set the content of our main activity to a card view 5.1. Import Card class: import com.google.android.glass.app.Card; 5.2. Declare the contents of the card in string.xml file:

<string name="card_text">Hello Smashtech!!!</string> <string name="card_footnote">Thanks for comming</string>

5.3. Set the card view to the content of the main activity:

Card card = new Card(this); card.setText(R.string.card_text); card.setFootnote(R.string.card_footnote); setContentView(card.getView());

Helloworld app 6. Run the app as an Android application 7. You will see the Android Device Chooser window, that will allow us to pick up the glasses where we want to run the app:

Helloworld app

8. And there you have it:
