			<description><![CDATA[Hi. Do you know how to do this same thing using the SensorManager.getOrientation( ) method. This is working really well, but the Sensor.TYPE_ORIENTATIO N is deprecated now.]]></description>

			<description><![CDATA[Hi Sebastian - thanks for the feedback! This tutorial went through a total rewrite recently because when it was first written (i.e. the version you saw) the sensor simulator was aimed at Android 1.5. Versions 1.6+ were incompatible. No longer! It now uses the current OI simulator and is aimed at Android 1.6+. The app was enhanced to support both hardware and software sensors using a proxy class, and during this work your points were addressed.]]></description>

			<description><![CDATA[Greetings I've been following this tutorial and I think is totally great, bu t I have a couple of questions that make me get confused about sensor programming. According to http://developer.android.com/reference/android/hardware/SensorEvent.html, all sensor values are returned as angles in degrees, but here, in your tutorial, you are using them as rectangle co-ordinates... and as far as I know they are not the same.. are they? Why can you use angles as co-ordinates? I don't know if i explain myself correctly or i'm too dumb to understand it.... but i don't really get it Thank you very much]]></description>

			<description><![CDATA[2 things that should / could be changed. a) No need to register SensorListener (deprecated as of now) in both onCreate and onResume as onResume always gets called after starting the app. Registering in onResume and unregister in onPause is what most applications should do. b) Math.atan() + many if/then clauses can be simplified to Math.atan2(x,y) which does the same thing in 1 command - if I got your math right :) and c) why do you register for Magnetic Field + Acceleration Sensors? The Data is just ignored.]]></description>
