S-View cover detection [magnetic sensor]

Question

I want to write an app for the Samsung S-View cover. To find out if the cover is closed I want to use the magnet which is in the cover and not the light sensor. I tried for my own with the deafult Android magnetic API:

SensorManager manager = (SensorManager) getSystemService(SENSOR_SERVICE);
Sensor s = manager.getDefaultSensor(Sensor.TYPE_MAGNETIC_FIELD);
manager.registerListener(this, s, SensorManager.SENSOR_DELAY_NORMAL);

tv.setText(event.values[2]);

but I do not know how to interpret the numbers. Of course I tried with the x-axis and y-axis too. They depends on the axis how I hold my phone and there is not a big difference if I have the Flip cover behind or in front of my phone. Do you have any ideas how I can find out if the cover is in front of my phone using the magnetic sensor? Do I have to use the uncalibrated sensor or did I do something else wrong?

Answer 1

I do believe this feature is made by the magnetic sersor, available in standard android API. Anyway, run an experiment with the smart cover to see if you can use that data.
