How to record and save a video using Google Glass

Question

I am fairly new to android studio and developing with android. I have been trying this for months now, I need to record and save a video using Google Glass. The code that I currently have follows. This is code inspired from https://developers.google.com/glass/develop/gdk/camera#images

When I run this process, the video will start recording and then when the recording is stopped, it will give me the option "tap to accept" When I tap, nothing happens. I understand this is because my method "processVideoWhenReady" does absolutely nothing.

I would like to know if anyone could help me with what I should include in that method to save the video and allow it to be viewed by the user within my application.

Any literature or websites that have useful information about developing for Google Glass would also be a huge help if possible. Google's documentation doesn't seem very helpful to me and very limited.

                    }
                }

            }
        };

        observer.startWatching();
    }
}
