Has anyone tried testing SensorEvents on Nexus S with gingerbread 2.3 What all SensorEvents does it support ? Specifically I am looking for these :
Sensor.TYPE_GRAVITY
Sensor.TYPE_LINEAR_ACCELERATION
and
Sensor.TYPE_ROTATION_VECTOR
Sensor.TYPE_GYROSCOPE
Can someone provide output of these events ? Does it support all of them ? This question is related to my old post for separating gravity from accelerometer readings found here.
Using the latest SDK downloaded a couple days ago (Android 2.3 API level 9) I see all the types you list. On a Nexus S a sensor listener for TYPE_GYROSCOPE and SENSOR_DELAY_UI generates a sensor changed event about every 10 msec:
e SensorEvent (id=830009808440)
accuracy 0
sensor Sensor (id=830009014296)
mHandle 5
mLegacyType 0
mMaxRange 34.906586
mMinDelay 1200

For TYPE_ROTATION_VECTOR I get an event about every 60 msec:
e SensorEvent (id=830009257568)
accuracy 3
sensor Sensor (id=830009236640)

For TYPE_LINEAR_ACCELERATION events also come in around every 60 msec:
e SensorEvent (id=830009389592)
accuracy 3
sensor Sensor (id=830009013408)

For TYPE_GRAVITY events come in around every 60 msec:
e SensorEvent (id=830009037864)

sensor Sensor (id=830009017880)
mHandle 1600615030
