 <p>Instead of opening the Google Glass camera app, you could take the picture yourself: <a href="http://developer.android.com/training/camera/cameradirect.html" rel="nofollow">http://developer.android.com/training/camera/cameradirect.html</a></p> <p>This is even mentioned in the GDK reference:</p> <blockquote> <p>Building your own logic with the Android Camera API. Follow these guidelines if you are using this method:</p> <ul> <li>Take a picture on a camera button click and a video on a long click, just like Glass does.</li> <li>Indicate to the user whether a picture was taken or a video was recorded.</li> <li>Keep the screen on during capture.</li> </ul> </blockquote>
