About Google Glass
Overview
Google Glass is a wearable computer with
an optical head-mounted display (OHMD)
that is being developed by Google in the
Project Glass research and development
project, with a mission of producing a
mass-market ubiquitous computer.
Google Glass displays information in a
smartphone-like hands-free format, that
can communicate with the Internet via
natural language voice commands.

Location and Sensors
LocationManager locationManager; // initialized elsewhere
// This example requests fine accuracy and requires altitude, but
// these criteria could be whatever you want.
Criteria criteria = new Criteria();
criteria.setAccuracy(Criteria.ACCURACY_FINE);
criteria.setAltitudeRequired(true);
List<String> providers = locationManager.getProviders(
criteria, true /* enabledOnly */);
for (String provider : providers) {
locationManager.requestLocationUpdates(provider, minTime,
minDistance, listener);
}

Location and Sensors
The following Android API sensors are supported on Glass:
Sensor.TYPE_ACCELEROMETER
Sensor.TYPE_GRAVITY
Sensor.TYPE_GYROSCOPE
Sensor.TYPE_LIGHT
Sensor.TYPE_LINEAR_ACCELERATION
Sensor.TYPE_MAGNETIC_FIELD
Sensor.TYPE_ORIENTATION (Deprecated, use SensorManager.getOrientation() instead.)
Sensor.TYPE_ROTATION_VECTOR
Source: https://developers.google.com/glass/develop/gdk/location-sensors
Camera
You have two options for capturing images or video:
 Calling the built-in camera activity with startActivityForResult().
Use this option when possible.
 Building your own logic with the Android Camera API.
Follow these guidelines if you are using this method:
 Take a picture on a camera button click and a video on a long click, just like
Glass does.
 Indicate to the user whether a picture was taken or a video was recorded.
 Keep the screen on during capture.

Camera Issues
Scrambled Embedded Preview
Camera.Parameters params = camera.getParameters();
params.setPreviewFpsRange(30000, 30000);
camera.setParameters(params);
