XE12 Release Notes

On December 17, 2013 Google released a major update for Glass right before the end of the year. Many of the updates that are released with XE12 were requests by many people in the community.

iOS app


MyGlass app is finally available on the App Store for many Glass explorers that use iOS devices. This now allows iOS devices access to many features that Android users have with Google Glass. Some features that this allows are:

  • Set up Glass
  • Get turn-by-turn directions
  • Add new contacts
  • Turn on Glassware

Google Play Music Menu








XE12 now allows you to have more control of your music with the Listen action menu. You can now choose to listen to all of your playlists, and if you are subscribed to All Access you can also choose Im Feeling Lucky Radio to live dangerously when listing to music.

Screen Lock








One of the most requested feature for Glass is a form of secruity. Google has answered this request with the Screen Lock feature that requires to match a pattern designed using swipe or tap combinations. The lock is turned on every time you deactivate your device or whenever the On-Head detection detects you have taken glass off.

Hangouts Glassware








With the recent SMS/MMS integration update for Hangouts, you can now send and receive Hangout chats via Glass. This is a great feature for those who use Hangouts as their main SMS application instead of the default messaging application.

YouTube Glassware









Another new addition to the list of official Glassware is the new YouTube application. Now when you take videos with your Glass you can share directly and upload it to your YouTube channel. Share your world through your eyes now with YouTube.









For those who missed WINK due to the update in XE11 that broke this feature, it is now reborn in XE12. Wink is a great way to take pictures by simply…winking! This application was created by community developer Mike DiGiovanni. I find this feature to be very useful to take pictures if your hands are busy and to skips the voice command to take a picture. Do not forget to check out Jeremy Sciarappa overview video on Wink.

Smart Talk with Glass

Google has updated the glass communication with a larger sense of questions. Now you can say “Ok Glass, Google How far to Brooklyn” and Glass will tell your the distance from your current location. Another great feature is Glass can be your nutritionist! Try, “Ok Glass, Google How many calories in a banana” and it will give you your answer! This is a very nice addition to glass as I can see a lot more updates similar to this in the future.

No more “Sent Through Glass”

This was one of the most brought up topic in the community that most explorers disliked the most. When you would normally send a text message it would display at the bottom “Sent Through Glass” and many users did not like this feature at all. Google listened to everyone’s opinion and decided to remove it, but not completely. If you send an email the lovely quote will still show up near the bottom of your signature (which is not all that bad).

Guest Mode?

Google decided to remove Guest Mode in XE12 and not for a silly reason. Google stated in their  release notes

“Why’d we get rid of Guest Mode? Maintaining features in Guest Mode was an extra burden on developers. That’s time we’d rather spend getting out new features.”

I agree with this remark as I personally never really used Guest Mode and would rather screen cast glass on my phone and take control of glass if the user would mess up or not know what to do. For those who would still rather not have anyone messing with their account, Google still allows you to create a new demo account here.

Wall Street Journal


You can now read and listen to the news you need with the Wall Street Journal glassware application. WSJ will update your glassware with Breaking News, Politics, Technology, Business and more!

Weather Alert


The new Weather Alert  glassware keeps you informed about approaching severe weather by sending updates to your glass in real time. You can choose from over 120 alerts to customize which alerts you would like to be alerted by.



No this is not another feature to take a picture. Winkfeed lets you stay up to date with all of your favorite news sites and RSS feeds. You can choose which feesds Winkfeed will directly update to your glass and easily tap and save to Pocket.

GDK Updates

Last but not least, Google has made some changes to the GDK and Mirror API in the latest XE12 release. You can find all the detailed release notes here. If you have yet to develop any Glassware take a quick look at the GDK documentation.

XE12 has brought a lot of new changes to Google Glass. What makes this update very special is that Google has listened to many of the requests made by those who speak up and give their opinions on Google+ and on the Glass community page. Looking forward to see what future updates are to come!

Enable Debug Mode on your Google Glass

To allow full control of your Google Glass you must first turn on Debug Mode. This will allow you to connect ADB to your Glass as well begin to code and utilize Glass to your machine. First make sure that you have your Glass turned on. Once it is fully powered on make sure you are at the “ok glass” screen.

Now swipe your finger toward the back of your head (Cards to the left) until you reach your “Settings” card.


Tap the side of your Glass to enter the settings sub-menu. Swipe toward the front of your glass (Cards to the right) until your see “Device Info”.


Tap on the this card to pull up additional information on the device. Swipe forward (Cards to the right) until you see “Turn on debug”


Now tap your Glass and you will now have Debug Mode turned on! If you navigate back to the same card, it will say “Turn off debug” in case you want to disable debug mode at a later point. With Debug Mode enabled you now have the power to install third party Glassware, mirror Glass to your computer and other great development features. Keep in mind to only tinker with your Glass at your own risk . If you have any questions or concerns feel free to ask!

Google Glass Drivers – Windows

When developing applications for a device, it is very important to have proper drivers. Installing Google Glass drivers is not so easy as it should be. If you are running MAC OS or Linux you do not have to worry about installing Glass drivers. For the ones running Windows there are a few tweaks we must do to android_winusb.inf
Before you begin, verify that the Google USB Driver is installed through the Android SDK Manager under “Extra”.

SDK Google USB


Next step is only for Windows 8 users. We have to Disable Driver Signature Verification. This is the main issue that prevents Glass drivers to install properly in Windows.

Press Win + I to bring up the Settings side bar. Then press the Change PC Settings link.


When the left side panel opens, select “Update and Recovery”.


Next click on the Recovery link on the left hand side.


On the right hand side, you will see “Advanced startup” and select the link to “Restart now”.


Once your computer fully reboots into Advanced settings, Select the “Troubleshoot” option.


Once in the Advanced Tools section, select “Advanced options”.


Next step you want to change the startup behavior in Windows, to do that select “Start Settings”


Since this will change how Windows will boot, we have to restart the system one more time


Last but not least, you will see a list of settings you can change. We are looking to select #7 “Disable driver signature enforcement”. To select that option we use our F-keys. Press “F7”. Your computer will now boot into Windows and the Driver Signature Verification will now be disabled.

Currently the Android SDK Manager does not have Glass drivers in its updates. So we have to manually add a snippet to the USB driver file. Navigate to your ADT bundle->sdk->extras->google->usb_driver and open android_winusb.inf in any text editor. In the file you will see two sections, [Google.NTx86] and [Google.NTamd64]. At the bottom of each section you will have to add the Google Glass snippet below:

;Google Glass
%SingleAdbInterface% = USB_Install, USB\VID_18D1&PID_4E11&REV_0216
%CompositeAdbInterface% = USB_Install, USB\VID_18D1&PID_4E11&MI_01
%SingleAdbInterface% = USB_Install, USB\VID_18D1&PID_9001&REV_0216
%CompositeAdbInterface% = USB_Install, USB\VID_18D1&PID_9001&MI_01

Once you have added this snippet to the bottom of each section in the android_winusb.inf file make sure you save all changes to the file. 

Now open Device Manager and right click on Glass1 under “Other devices” and select “Update Driver Software”. When prompted on how to search for driver software, select “Browse my computer for driver software” and navigate to ADT bundle->sdk->extras->google->usb_driver. Once the driver will be installing, you will be prompted by a Windows Security warning, this warning occurs because we have disabled driver signature verification.


Select “Install this driver software anyway”. Once the installation is complete, your Google Glass will be recognized as an Android Composite ADB Interface.

To verify that our Google Glass is working now with the correct USB drivers we will use ADB – Android Debug Bridge to communicate with Glass. Navigate to ADT bundle->sdk->plaform-tools and in the folder you will see adb.exe which is what we need to test with Glass. Hold down SHIFT and right-click to select “Open command window here”. This will pull up a command window that is already pointed to the path we need to run ADB commands. The command we will run is adb devices. Once the command has finished starting, you will see “List of devices attached”. If all is done correctly you will see a device listed; if no device are listed then that means the installation of the drivers were not successful or incomplete.
