You can probably safely assume that most devices will have an accelerometer, which measures gravity on 3 axes, as well as a compass. Newer devices may have gyroscopes which can be more helpful for detecting different types of motion. Here's a very helpful link which may describe more of what goes on with the sensors in phones, and which to use when, when available: Sensor Fusion on Android Devices: http://www.youtube.com/watch?v=C7JQ7Rpwn2k -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
