Thanks for your response.
Is there any documentation on the web that contains some of the
parameters(already tuned to some extent) that I can try with. For instance I
found couple of examples talking about shake and there is a mention of:
(accelationSquareRoot >= 2) means shake detected,
This is the complete code for this:
public void onSensorChanged(SensorEvent event) {
// TODO
if (event.sensor.getType() == Sensor.TYPE_ACCELEROMETER) {
float[] values = event.values;
// Movement
float x = values[0];
float y = values[1];
float z = values[2];
float accelationSquareRoot = (x * x + y * y + z * z)
/ (SensorManager.GRAVITY_EARTH * SensorManager.GRAVITY_EARTH);
long actualTime = System.currentTimeMillis();
if (accelationSquareRoot >= 2) //
{
if (actualTime - lastUpdate < 200) {
return;
}
lastUpdate = actualTime;
// Shake Detected
// TODO: do something
}
}
}
Thanks in advance.
Regards,
KK
