I think what you're after is the difference in values between X (left
and right), Y (up and down), Z (toward you and away).
My code looks something like this:
public void onSensorChanged(SensorEvent event) {
long curTime = System.currentTimeMillis();
x = Math.abs(event.values[0]);
y = Math.abs(event.values[1]);
z = Math.abs(event.values[2]);
if((x+y+z) > ACCEL_THRESHOLD){
shakeCount++;
shakeLevel += (x+y+z);
if(shakeCount >= 3){
shakeCount = 0;
shakeLevel = 0;
}
if(shakeLevel > SHAKE_THRESHOLD){
// Do something because the phone has been shaken.
}
}
}
What I'm doing is looking for repetitive amounts of movement in any
direction, over a certain threshold, over time. You could break this
down into counts for X, Y, and Z rather then adding them all together
like I am. Then, just play with different thresholds that trigger when
you expect.
